Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

Fig. 1 shows a flow diagram of a communication method in an iOS system according to an embodiment of the invention. As shown in fig. 1, the method includes:

step S110, determining a local port designated by the first APP.

Communication of the APP needs to be achieved through a port, for example, the APP achieves data communication with a corresponding server through a software port. The present invention needs to solve the problem of communication between different APPs in the iOS system or between an APP and other products, so that a local port of the APP needs to be determined, so that the APP receives or sends a request through the local port to implement communication. The first APP is an APP that needs to communicate, and may be any APP. Taking a music playing APP as an example, determining that a local port designated by the music playing APP is 8001, and the music playing APP sends a request to the outside or receives requests of other APPs through the 8001 port.

And step S120, establishing socket connection with the first APP through the local port specified by the first APP.

Before communication is effected, a connection needs to be established. Establishing a socket connection is establishing a long connection. After the local port of the first APP is determined, the first APP monitors the local port, that is, monitors the network state in real time. And other products send a socket connection request to the local port, and indicate the address and the port of the socket of the first APP. And when monitoring the connection request, the first APP responds to the socket connection request, establishes a new thread, and returns the socket description so as to enable other products to formally establish a socket connection with the first APP. Socket connection established through the local port is higher in reliability, one-to-many communication can be achieved, and communication efficiency can be effectively improved.

Using music playing APP and video playing APP as examples, the local port of music playing APP is 8001, the video playing APP sends the socket connection request to the 8001 port, the music playing APP monitors the socket connection request, a description of the socket is returned to the video playing APP, and after the video playing APP confirms the description, the video playing APP formally establishes socket connection with the music playing APP.

Step S130, communication is carried out based on socket connection.

After the Socket connection is established, the first APP can communicate with other products on the thread established by the Socket connection. For example, after the socket connection is established between the music playing APP and the video playing APP, the music playing APP sends data of a certain music to the video playing APP through a thread established by the socket connection, so as to obtain a related video of the music, such as the music MV or the playing video. Communication is simple and convenient based on socket connection, both sides of connection can send data to each other, and communication efficiency is higher.

According to the communication method in the iOS system, a local port specified by a first APP is determined, socket connection is established with the first APP through the local port specified by the first APP, and communication is carried out based on the socket connection. Socket connects can realize the communication between other independent products and the first APP, and Socket connection reliability through the local port of first APP is established is higher, can realize the communication of a pair of many moreover, and a plurality of independent products are connected communication with first APP, and the both sides of connecting all can send data to the other side, and communication is simple convenient, can improve communication efficiency effectively.

In an embodiment of the present invention, in the method shown in fig. 1, the determining of the local port specified by the first APP in step S110 includes one or more of the following: determining a port number of a local port appointed by a first APP according to preset configuration information; receiving a port number of a local port designated by a first APP issued by a server; and extracting the port number of the local port specified by the first APP from the scheme link sent by the first APP.

The embodiment provides various specific implementation methods for determining the local port specified by the first APP. Each port needs a port number to realize connection and communication, the port number of the local port of the APP is configuration information of the APP, the port number can be defined and modified in a configuration file of the APP, and when the port number is determined in the configuration file of the APP, a request is directly sent to the port number to realize connection establishment with the APP, communication and the like. For example, in the configuration file of the music playing APP, the port number of the local port is determined to be 8001. When the port number of the local port needs to be modified, the port number needs to be modified in the configuration file. The method for determining the port number in the configuration file of the APP can directly determine a fixed port number, is convenient for other APPs to send connection requests, and is helpful for improving accuracy and working efficiency. The port number of the APP local port is preset, and the phenomenon that the port number is repeated to influence normal communication can be avoided.

If the port number of the local port is not set in the configuration file of the APP, the port number of the local port of the APP can be determined through the server. In particular, the second APP needs to establish connection and communication with the first APP. The first APP and the second APP are both connected to the same server, the server determines the port number of the local port of the first APP, and then the port number is issued to the second APP. And the second APP sends a connection request to the port number to establish connection with the first APP so as to realize communication. The method for issuing the port number by the server is adopted, and the connection is established through the dynamic port number, so that the problem of insufficient port numbers caused by excessive connection can be effectively solved, and the connection communication with the first APP is realized.

in the iOS system, different APPs are also called mutually through scheme links. Referring to this manner, the port number of the local port specified by the first APP may be inserted into the scheme link sent by the first APP. When the second APP is called through the scheme link, the second APP extracts the port number of the local port specified by the first APP from the scheme link, and connection and communication with the first APP are achieved. The reliability of this mode is higher, realizes more easily.

The three manners for determining the port number of the local port specified by the first APP may be one of the manners, or may be multiple manners combined, and the determination is specifically performed according to a use requirement.

In an embodiment of the present invention, in the method shown in fig. 1, the establishing a socket connection with the first APP through the local port specified by the first APP in step S120 includes: and sending a request to a local port appointed by the first APP, and if the request is not responded within appointed time, informing the first APP to start the local socket service through a scheme link.

The embodiment provides a specific way for establishing socket connection with the first APP. Usually, the first APP monitors the local port, and responds to the transmitted socket connection request, so that establishment of the socket connection can be realized. Generally, in order to improve the work efficiency, the first APP is required to respond to the socket connection request within a specified time. If the first APP does not respond to the socket connection request within the specified time, there may be a case where the first APP does not start the local socket service, resulting in a failure to respond in time. At this time, the first APP may be notified through the scheme link to start the local socket service. The Scheme link generally provides a path for jumping or opening the APP, and inserts information for starting the local socket service of the first APP into the Scheme link and sends the information to the user. Clicking on the scheme link by the user can enable the first APP to start a local socket service, so that a socket connection request can be responded.

In one embodiment of the present invention, as in the method shown in fig. 1, the method further comprises: and starting a local socket service, and establishing socket connection with the webpage or the second APP through a specified local port to perform communication.

The above embodiment provides that other independent products send a connection request to the first APP through the local port of the first APP, and the first APP passively establishes a connection. In order to improve the initiative of the first APP, the embodiment provides a specific way that the first APP actively sends the connection request to other independent products. For example, the first APP needs to communicate with the second APP, starts a local socket service, and actively sends a connection request to a local port specified by the second APP, so that the second APP responds and establishes a socket connection for communication. The first APP and the second APP can be any APPs, the first APP and the second APP are only used for distinguishing different APPs, and names of the APPs are not limited. This embodiment can realize that first APP initiatively establishes with other products and is connected, effectively improves the initiative of first APP. That is, the APP may receive a connection request and respond to establishing a connection; or actively sending a connection request outwards to establish connection.

Still take above-mentioned music broadcast APP and video broadcast APP as an example, the local port of video broadcast APP is 8001, and music broadcast APP starts the socket service of self, initiatively sends socket connection request to video broadcast APP's 8001 port, and this socket connection request is monitored to video broadcast APP, returns the socket description to music broadcast APP, and after music broadcast APP confirms this description, formally establishes socket connection with video broadcast APP and communicates.

Of course, the first APP may also implement connection communication with the web page by sending a connection request to the local port of the web page, and the specific implementation method is the same as the implementation method of the second APP. By adopting the mode, the connection communication between any two independent products can be realized, and the problem that the independent products cannot communicate with each other is effectively solved.

In one embodiment of the present invention, as in the method shown in fig. 1, the method is applied to a web page and/or a second APP.

As can be seen from the above, the communication method can be applied to any product in the iOS system. The webpage can specify a local port, and other products send a socket connection request to the local port, for example, the first APP sends the socket connection request to the local port, so that the socket connection with the webpage is established for communication. The webpage can also send a connection request to the outside through the local port to realize communication with other products. The second APP can also designate a local port, the first APP sends a socket connection request to the local port, and the socket connection is established with the second APP for communication.

In an embodiment of the present invention, as in the method shown in fig. 1, when applied to the second APP, the method further includes: declaring for the second APP an authority to run a specified function; after the second APP is started, applying for a background task running a specified function; and when the second APP is switched to the background, the background resident is realized according to the background task.

Known from the above embodiment, after the second APP establishes the socket connection with the first APP, if communication is performed, the second APP needs to keep the running state to receive the communication data sent by the first APP. However, in general, when the second APP exits from the foreground task and is suspended by the system for more than the limit time, the system may end the process of the second APP in the background task. The second APP is therefore not in an operational state and cannot receive communication data of the first APP. The embodiment provides a mode for implementing the second APP to be resident in the background task, so that the second APP can keep a running state in the background task and receive the communication data of the first APP.

The designated function is any function that can be run after the APP is started, and in a general case, the operating system does not end all processes of the APP in the background task when the designated function is running. That is, after the specified function is run, the APP can execute the relevant operation in the background task without time constraint. For example, after the music playing APP starts playing music, even if the device locks the screen or switches to other APPs, the operating system does not forcibly end the music playing APP, so that the music playing APP can always execute the music playing operation, wherein the function of playing music by using multimedia is a specific function. The right to run the specified function is declared in the second APP, i.e. the second APP is given the right to use the specified function.

After the second APP is started, the background task of the specified function is applied to be run, namely, the specified function is run in the background task. When the second APP is finished from the foreground task and is suspended by the operating system, the specified function can still continue to run in the background task. And moreover, the appointed function can reduce occupied resources in background tasks, and other APPs can be ensured to normally run. The second APP is switched to the background, namely the second APP is suspended, at the moment, the specified function is still operated in the background task, so that the operating system cannot forcibly end the specified function, the APP cannot be completely ended, the allowed operation is continuously executed in the background task, and the background resident is realized.

The embodiment declares the authority to run the specified function for the second APP; after the second APP is started, applying for a background task running a specified function; and when the second APP is switched to the background, the background resident is realized according to the background task. The appointed function can realize that under general condition, operating system can not force the operation of automatic end APP, makes APP can be unrestricted time's restraint, and is hung and changes into the backstage operation, realizes that the backstage is resident. The appointed function runs in the background task, so that occupied resources can be reduced, and sufficient resources are ensured to be supplied to other APPs for normal running.

In an embodiment of the present invention, in the method for implementing background resident of the second APP, declaring, for the second APP, a right to run a specified function includes: the right to run the specified function is declared in the attribute list of the second APP.

The attribute list of the APP manages functions which the APP can run, and the declaration of the authority is to define new function authority in the attribute list of the APP. Only the function declared successful in the attribute list can be run by the operating system at APP start-up. Therefore, the authority of the specified function is declared in the attribute list of the APP, the specified function can be automatically operated when the APP is started, and therefore the APP can be ensured to reside in the background.

In an embodiment of the present invention, in the method for implementing background resident of the second APP, after the second APP is started, applying for a background task running a specified function includes: and applying for a background task in an AppDelegate of a second APP.

The embodiment provides a specific implementation method for applying for running a background task with a specified function. AppDelegate is a class file in APP development, and is used for processing events at the APP level, such as OpenURL, handoff, intent and the like of APP. Accordingly, the application of the background task is also implemented in appdelete. That is to say, a background task for running a specified function is written in the APP delete, and when the APP is started, the task in the APP delete is correspondingly run. And the application of the background task with the specified function is carried out in the AppDelegate, and the method is simple and is easier to realize.

In an embodiment of the present invention, in the method for implementing background resident of the second APP, applying for a background task running a specified function includes: and setting the designated priority for the background task so that the background task does not influence the designated functions of other applications when running in the background.

A given function is a function that can be executed, and there may be cases where it can be executed by a plurality of different APPs. For example, the specific function in the above example is a multimedia playing function, the music APP may run the function, and the video APP may also run the function. In order to avoid conflict between different APPs when the same appointed function is operated, the priority of the APP which can operate the same appointed function is set in the background task, and the background task operates the appointed function according to the priority.

Or, taking the above multimedia playing function as an example, the priority of the multimedia playing function of the music APP is set to be the highest, and the priority of the multimedia playing function of the video APP is set to be the next. The user opens music APP at first and plays the music, has switched over to video APP and watches the video for a period of time, and video APP moves in the foreground task this moment, uses the multimedia playing function, and music APP withdraws from to the unable use of backstage task. After a while, the user quits the video APP, at the moment, the video APP and the music APP are in background tasks, and the music APP plays music by using the multimedia playing function due to the fact that the multimedia playing function of the music APP is highest in priority.

In an embodiment of the present invention, in the method for implementing background resident of the second APP, the designated function is a music playing function and/or a positioning function.

The present embodiment provides a specific implementation of the specified function. The designated function is a music playing function or a positioning function, or both functions can be realized. The multimedia of music instant music calling equipment realizes the music broadcast, consequently is hung up when the APP, and the music instant music shifts into background task operation back, and operating system judges this APP still need operate in the background task, can not end the APP by force, makes APP unrestricted time's restraint, and realizes resident in the background task.

The positioning function calls a positioning system of the device, for example, a GPS positioning system is needed to realize positioning. When the APP is suspended, the positioning function used by the APP still runs in the background task, the operating system judges that the APP still needs to perform certain operation, the APP cannot be forcibly ended, the APP is enabled to be resident in the background task without being limited by time.

The music playing function is adopted to realize APP background resident, and the specific realization mode can be as follows: and continuously playing preset silent music through the background task.

The APP can be judged by the operating system to still need to run in the background task only if the APP needs to run music playing. However, the music playing function is to realize that the APP is resident in the background task of the operating system, and does not need to actually play music. By adopting the mode of playing a section of silent music, the method can realize that the APP is resident in background tasks and can also avoid influencing normal use of equipment or other APPs of users. For example, when a game APP is suspended in a background task, the normal music playing function of the music playing APP is not affected because silent music is played. The music playing function needs to be operated all the time, namely, silent music needs to be played continuously, the APP can be made to reside in the background, and a mode of playing a single silent music in a circulating mode can be adopted, namely, after the current silent music playing is finished, timing is started again and then the silent music is played again. Of course, the interval time may also be set, for example, after delaying for 2min after the end of playing the current silent music, the playing is resumed.

When the positioning function is adopted to realize APP background resident, the specific realization method can be as follows: and refreshing the position according to a preset strategy.

The positioning function requires a positioning operation, and can be determined by the operating system to execute a certain operation. Therefore, the positioning function in the APP needs to perform positioning operation at variable time. And refreshing the position by using a preset strategy, namely enabling the positioning function of the APP to perform positioning operation by using the preset strategy. For example, the positioning function performs a positioning operation at an interval of 2min to update the current position of the APP. Or setting a fixed position refreshing time, such as positioning operation by the positioning function at the integral point and the half point.
