Detailed Description

Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

It should be noted that the respective technical features mentioned in each embodiment of the present invention may be combined in any combination without departing from the spirit of the present invention.

In the embodiment of the invention, when the user browses the page by using the navigation function of the navigation control, the page browsed by the user based on the current navigation control is recorded. When a user wants to return to a certain page, the navigation return is triggered through a first trigger event. And at this time, the title of the browsed page is displayed to the user for the user to select. After a user selects a certain title, the user jumps to a page corresponding to the title.

Fig. 1 is a schematic diagram of a main flow of a method for navigating fallback according to an embodiment of the present invention, as shown in fig. 1, the method for navigating fallback includes:

s101, after a navigation control to be tracked is determined, adding the title of each page container which is jumped by a user based on the navigation control into a stack to form a title stack;

step S102, when a preset first trigger event is monitored, visually displaying the title stack, and taking a title selected by a user from the title stack as a title to be backed;

and step S103, acquiring a page container corresponding to the title to be returned, and returning from the current page to the page corresponding to the page container.

Optionally, the first triggering event is a non-button event. The non-button event refers to an operation event which is not based on a button, such as a gesture action performed within a certain distance range on the current page, or shaking the mobile phone, or sliding left and right on the current page, or the like, or an operation event based on an operation button of the navigation control, such as double-clicking or pressing a return button of the navigation control.

The navigation backspacing is triggered through the non-button event, an independent button does not need to be added, the display space of the navigation bar can be saved, and the utilization rate of the navigation function area is improved. In the embodiment of the invention, the title selected by the user from the title stack is used as the title to be backed, so that the user can specifically select which page to back to, and the navigation back is more flexible and convenient.

The navigation backspacing method is realized based on the navigation control of the system. FIG. 2 is a schematic diagram of a technical architecture of a navigation control, in which rectangular boxes represent property elements of the navigation control and circular boxes represent functions provided by the navigation control. As shown in fig. 2, the navigation control mainly consists of a container array and operation buttons (including a return button, various customized function buttons, and the like), and mainly provides a pop method and a push method. And the page container is a unit for displaying an interface and receiving view processing. The navigation control is implemented only for the page container and cannot store other elements that are customized. The pop and push methods provided by the navigation control are as follows:

(1) The push method provides a function of page jump to a new page, and adds a new page container into the container array;

(2) The pop method provides a jump function from the current page back to an old page and removes the containers behind the old page (excluding the old page to which the jump is made) from the container array.

In some embodiments, the navigation backspacing method may be implemented in a singleton mode, that is, each navigation backspacing method manages one navigation control and handles the backspacing operation of the navigation control. The core structure of the singleton schema contains only one special class called singleton. The singleton mode can ensure that one class has only one instance, namely, one class has only one object instance. The navigation backspacing method of the embodiment of the invention has wide application range, namely global access can be realized, so that navigation backspacing can be more conveniently carried out by adopting a single-case mode.

According to the embodiment of the invention, the title of each page container which is jumped by the user based on the navigation control is added into the stack to form a title stack. FIG. 3 is a schematic diagram of the technical architecture of a stack, in which rectangular boxes represent property elements of the stack control and round boxes represent functionality provided by the stack control. As shown in FIG. 3, the stack control is mainly composed of an array of elements and provides pop and push methods. The functions of the stack control are similar to the functions of part of the navigation control, and compared with the realization of the navigation control which is only aiming at a page container and cannot store other self-defined elements, the stack space can store the self-defined elements. The pop and push methods provided by the stack control are as follows:

(1) The push method provides for the sequential addition of elements of any type into an array of elements. For example: the element index of the element array added firstly is 0, the element index added later is 1, the indexes added later are analogized, and 1 is added each time;

(2) The pop method provides two functions:

1) Deleting the element with the largest element index in the element array;

2) The specified element and elements larger than the element index of the element are deleted.

After the navigation control to be tracked is determined, the method further comprises the following steps: and storing the title of each jumped page container and the corresponding page container thereof in a Key-Value form a mapping table of the title and the page container. Acquiring the page container corresponding to the to-be-rolled-back title may include: acquiring a container identifier corresponding to the title to be backed according to the title to be backed and the mapping table; and acquiring a page container corresponding to the title to be returned according to the container identifier.

The mapping table for the header and page container is a dictionary type data stored in Key-Value form. Key is the title, value is the container identification. When a page needs to jump to a certain page, a page container for jumping to the page needs to be provided.

In the embodiment of the invention, the step of adding the title of each page container jumped by the user based on the navigation control into the stack to form the title stack and/or the step of storing the title of each jumped page container and the corresponding page container thereof in the form of Key-Value to form the mapping table of the title and the page container can also be realized by calling a push method. In order to avoid calling the push method of the navigation control after calling the push method, a code obfuscation mechanism may be used to form a title stack and/or form a mapping table of a title and page container.

The code obfuscation mechanism (method-swizzle) reorganizes and processes existing code so that obfuscated code performs the same function as pre-processed code. The obfuscated code still conforms to the original file format and instruction set, and the execution results are the same as before the obfuscation. The push method of the embodiment of the invention is called by adopting a code obfuscation mechanism, namely, when the push method of the navigation control is called, the title of the page container is obtained according to the page container, and the push method of the embodiment of the invention is automatically called.

By adopting a code confusion mechanism, on one hand, a calling code for calling the push method of the embodiment of the invention does not need to be independently set, and developers only call the method of the navigation control as in conventional development, so that the calling is convenient and efficient; on the other hand, the synchronization and the correspondence between the title stack and the mapping table and the container array in the navigation control can be ensured, and the rollback failure caused by the asynchronization of the title stack and the mapping table can be prevented. If the call codes for calling the push method and the pop method of the embodiment of the invention are independently set, the call codes are easy to miss call, which causes the miscall situation, thereby causing data inconsistency and rollback failure.

In the embodiment of the present invention, the step of adding the title of each page container skipped by the user based on the navigation control into the stack to form the title stack and/or the step of storing the title of each skipped page container and the corresponding page container thereof in the form of Key-Value to form the mapping table of the title and the page container may also be implemented by calling a push method. In some optional embodiments, an asynchronous manner is adopted to form a header stack and/or form a mapping table of a header and a page container, that is, invoking the push method of the embodiment of the present invention and invoking the push method of the navigation control are performed asynchronously. By adopting an asynchronous mode, the influence of steps of forming a title stack and/or forming a mapping table on the backspacing can be avoided, so that the efficiency of jumping to a page to be backspaced is not influenced by calling the push method of the embodiment of the invention, and the page is smoother in the backspacing process.

The navigation backspacing method of the embodiment of the invention can also comprise the following steps: when a preset second trigger event is monitored, taking the title with the second largest title index in the title stack as the title to be backed; and the title index of each title in the title stack is set in a self-increment mode. The second trigger event is a return event of the navigation control, that is, an event that can jump from the current page to a page previous to the current page when the page is browsed based on the navigation control, for example, a return button of the navigation control is clicked. When a second trigger event is monitored, the current page is returned to the previous page, and the application range of the navigation backspacing method can be enlarged.

After returning from the current page to the page corresponding to the page container, the method may further include: deleting the title to be rolled back from the title stack; determining a title with a title index larger than that of the title to be backed off, and deleting the title from the title stack; and the title index of each title in the title stack is set in a self-increment mode. And after the rollback, deleting the title to be rolled back and the title with the title index larger than that of the title to be rolled back, and updating the title stack in real time according to the operation behavior of the user to ensure that the title to be rolled back is the stack top element in the title stack.

In the embodiment of the invention, the step of deleting the title to be rolled back and the title with the title index larger than that of the title to be rolled back after rolling back can also be realized by calling a pop method. In order to avoid calling the pop method of the embodiment of the present invention after calling the pop method of the navigation control, a code obfuscation mechanism may be adopted to perform the following steps: deleting the title to be rolled back from the title stack; and determining the title with the title index larger than that of the title to be backed, and deleting the title from the title stack. The pop method of the embodiment of the invention is called by adopting a code obfuscation mechanism, namely, when the pop method of the navigation control is called, the title of the page container is obtained according to the page container, and the pop method of the embodiment of the invention is automatically called. By adopting a code confusion mechanism, on one hand, a calling code for calling the push method of the embodiment of the invention does not need to be independently set, and developers only call the method of the navigation control as in conventional development, so that the calling is convenient and efficient; on the other hand, the synchronization and the correspondence between the title stack and the mapping table and the container array in the navigation control can be ensured, and the rollback failure caused by the asynchronization of the title stack and the mapping table can be prevented. If the call codes for calling the push method and the pop method of the embodiment of the invention are independently set, the call codes are easy to miss call, which causes the miscall situation, thereby causing data inconsistency and rollback failure.

In an alternative embodiment, the navigation control to be tracked is determined by using a weak reference mode. A weak reference refers to a way to reference an element that does not regenerate, take up system space. For example, the navigation control to be tracked is assigned to the execution main body of the method for navigating and backing according to the embodiment of the invention. The navigation backspacing method of the embodiment of the invention is bound with the navigation control to be tracked by adopting a weak reference mode, so that the system space is not occupied. In addition, a trigger event may also be added to the navigation rollback method of the embodiment of the present invention, for example, an event of double-clicking or re-pressing a return button of the navigation control is added as a first trigger event, and after the first trigger event occurs, a title in a title stack is visually displayed; for another example, an event of clicking a return button of the navigation control is added as a second trigger event, and after the second trigger event occurs, the pop method of the embodiment of the present invention is invoked.

After the page corresponding to the page container is returned from the current page, the method may further include: if the title index of the title to be backed is the minimum value of all the title indexes, clearing the title stack, the mapping table and the weak reference; and the title index of each title in the title stack is set in a self-increment mode. The embodiment of the invention can finish the tracking of the navigation control and clear the data generated in the tracking process after returning to the first page browsed by the user, thereby releasing the storage space in time.

In some embodiments, the title stack may be visually displayed by visually displaying the title stack to the uppermost layer of the current page using a modal box. A modal box is a dialog box on which a user mouse point or input cursor stays unless a valid closing means is taken. The modality box may present the titles in the title stack in a horizontal list or a vertical list. When a preset operation is performed on the modal box, for example, an index button in the modal box is clicked, or a peripheral region of the modal box is clicked, the modal box may be eliminated from the current page.

Fig. 4 is a schematic diagram of main modules of an apparatus for navigating a backspace control according to an embodiment of the present invention. As shown in fig. 4, the navigation back control 400 includes:

the pushing module 401 is configured to add a title of each page container skipped by the user based on the navigation control into a stack to form a title stack after determining the navigation control to be tracked;

a display module 402, configured to visually display the title stack when a preset first trigger event is monitored;

a determining module 403, configured to use a title selected by a user from the title stack as a title to be rolled back;

and the skip module 404 acquires a page container corresponding to the title to be backed, and backs to the page corresponding to the page container from the current page.

Optionally, the pushing module is further configured to, after determining the navigation control to be tracked, store the title of each skipped page container and the corresponding page container thereof in a Key-Value form to form a mapping table of the title and the page container;

Optionally, the determining module is further configured to:

Optionally, the press-in module is further configured to:

after the current page is returned to the page corresponding to the page container, deleting the title to be returned from the title stack; determining a title with a title index larger than that of the title to be backed, and deleting the title from the title stack;

Optionally, the navigation backspacing control is implemented in a singleton mode, that is, one navigation backspacing control manages one navigation control to be tracked, and handles the backspacing operation of the navigation control.

Optionally, the first triggering event is a non-button event.

In the practical application process, when the navigation backspacing control is used for the first time, an initialization operation needs to be performed to initialize the attribute elements of the navigation backspacing control.

Fig. 5 is a schematic diagram of a technical architecture of a navigation backspace control according to an alternative embodiment of the present invention, in which a rectangular box represents an attribute element of the navigation backspace control, and a circular box represents a function provided by the navigation backspace control. As shown in fig. 5, the navigation backspace control mainly has references for navigation, a title index view, a mapping table of titles and page containers, a title stack, and various functions shown in the figure.

Introduction of property elements of navigation backspacing control:

(1) Reference to navigation: when a navigation control needs to be tracked, assigning the navigation control as a navigation reference;

(2) Title stack: a stack control for storing headers (each page container is titled, and the headers describe the functions of the page containers);

(3) Title and page container mapping table: is dictionary type data stored in the form of key-Value. Key is a title, and Value is a container identifier;

(4) Title index view: the contents of the title stack are rendered to view elements on the interface.

Introduction of functions of the navigation backspacing control:

(1) The push method comprises the following steps: and adding the title of the newly-jumped page container into the title stack, and adding the title of the newly-jumped page container and the page container into a mapping table of the title and the page container in a key-Value form. The whole operation is executed asynchronously, so that the efficiency of jumping to a new interface is not influenced, and the fluency of the page is improved. The push function is called when the push method of the navigation control is executed. In order to prevent developers using the navigation backspacing control of the embodiment of the invention from calling the push method of the navigation control and then calling the push method of the navigation backspacing control, a code confusion mechanism can be adopted, namely when the push method of the navigation control is called, the title of the page container is obtained according to the page container, and the push method of the navigation backspacing control is automatically called;

(2) The pop method: and calling a pop method of the stack control to delete the last title in the title stack or delete the specified title and the title elements behind the title from the stack. The method is similar to a push method of a navigation backspacing control, and a code confusion mechanism can be adopted to confuse a pop method of the navigation control. Asynchronously executing a pop method of the navigation backspacing control after confusion;

(3) The show method comprises the following steps: displaying the title index view to the uppermost layer of the current page in a mode of a modal frame;

(4) The hide method: when the index on the title index view or the peripheral area of the title index view is clicked, the function of removing the title index view from the current page is achieved;

(5) The bind method comprises the following steps: the navigation control and the navigation backspacing control are bound together, specifically, the navigation control to be tracked is assigned to the navigation reference of the navigation backspacing control, and a single-click gesture event and a double-click gesture event are added to a return button of the navigation control. After a single-click gesture event occurs, calling a pop method of the navigation backspacing control, and after a double-click gesture event occurs, calling a show method of the navigation backspacing control;

(6) clear method: clearing the navigation reference, the title stack and the title and container mapping table;

(7) jump method: when clicking on the index on the title index view, the jump method is triggered. The jump method provides the function of returning to the page container corresponding to the currently clicked title. The jump method maps a currently clicked title in a mapping table of a de-title and a page container to obtain a corresponding page container, takes the corresponding page container as a parameter, transmits the parameter to a pop method of a navigation control through navigation reference, and backs to a page corresponding to the page container. If the title index corresponding to the currently clicked title is 0 (here, 0 represents the minimum value of all title indexes in the title stack), a clear method of the navigation backspace control is called.
