Detailed Description
The following description of the exemplary embodiments of the present application, taken in conjunction with the accompanying drawings, includes various details of the embodiments of the application for the understanding of the same, which are to be considered exemplary only. 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 present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Fig. 1 is a schematic diagram of a main flow of a view processing method according to a first embodiment of the present application, and as shown in fig. 1, the view processing method includes:
step S101, receiving a view processing request, and acquiring a corresponding sub-view identifier.
In this embodiment, an execution main body (for example, a processor of a terminal) of the view processing method may receive a view processing request sent by a user through a wired connection or a wireless connection. Specifically, the view processing request may be a request to acquire a content display state of the sub-view in the scroll view and display content in the sub-view based on the content display state. In particular, the content display state may include content fully visible, partially visible, and invisible; when partially visible, what the visible portion is, and so on. The sub-view identifier may be, for example, a position coordinate of the sub-view, a name of the sub-view, a size of the sub-view, or the like, and the specific content of the sub-view identifier is not limited in the embodiment of the present application.
Step S102, determining a parent view identifier corresponding to the child view identifier, calling a monitoring mechanism according to the child view identifier and the parent view identifier to monitor a parent view target object attribute corresponding to the parent view identifier, and calling a callback mechanism to update a child view target object attribute corresponding to the child view identifier in response to determining that the parent view target object attribute changes.
The child view is a small view in the parent view (i.e., the scroll view). The sub-view is not limited to specific displayed content, a text may be displayed, or a picture or a video may be displayed.
The execution principal may determine a corresponding parent view identification, e.g., a, from the child view identification, e.g., a. The executing agent may invoke a listener corresponding to the child view identification and the corresponding parent view identification to listen for the parent view target object attribute corresponding to the parent view identification based on the listening mechanism of the listener. The target object attribute may be, for example, a contentOffSet, which is an attribute of the uisrolview (i.e., the parent view), and represents a scroll offset of the uisrolview (i.e., the parent view), and when a change in the scroll offset of the parent view is detected (i.e., when the parent view is detected to be scrolled), the execution subject updates a value of the target object attribute.
Specifically, updating the sub-view target object attribute corresponding to the sub-view identifier includes:
determining a coordinate system of a current parent view corresponding to the parent view identification and a rolling direction of the current parent view; determining the position coordinates of the sub-view corresponding to the sub-view identification based on the coordinate system and the rolling direction; and updating the object attribute of the sub-view corresponding to the sub-view identification based on the position coordinate.
For example, the executing agent may first obtain the scroll offset of the latest parent view, that is, the contentOffSet of the latest uiscrilview, by listening to KVO of the contentOffSet attribute of the parent view. Then, the execution subject may convert the coordinates of the current sub-View (i.e. the sub-View) into the uiScrollView coordinate system, and calculate the position of the X or Y of the sub-View in the UIScrollView according to the scrolling direction of the UIScrollView, to obtain the current state (the current state of the sub-View may include content fully visible, partially visible and invisible; when partially visible, how much the visible part is, etc.) and the display size of the sub-View. And transmitting the calculation result to the user through a callback.
Specifically, updating the sub-view target object attribute corresponding to the sub-view identifier based on the position coordinates includes:
based on the position coordinates, the display portion size of the child view in the current parent view is determined. The display portion size, for example, the size of the child view from the top, bottom, left, and right margins of the current parent view. The execution principal may then update the child view in the parent view to identify the corresponding child view target object property based on the display portion size. The child view target object property, i.e., the child view, identifies the scroll offset of the corresponding child view relative to the parent view. Therefore, the content display state of the child view in the parent view and the position of the child view in the parent view can be accurately positioned.
Specifically, based on the size of the display part, updating the attribute of the sub-view target object corresponding to the sub-view identifier includes:
in response to determining that the display portion size is less than the preset threshold, determining that the display state is invisible, otherwise, visible. Specifically, when the size of the display portion of the sub-view is too small to be smaller than a preset threshold, the display state of the content of the sub-view is determined to be invisible, that is, the content of the sub-view is not shown. The preset threshold may be a preset size of a display portion where the corresponding content is visible. That is, the attribute of the sub-view target object corresponding to the sub-view identifier is updated to be invisible, and the sub-view corresponding to the sub-view identifier is not displayed.
Specifically, based on the size of the display part, updating the attribute of the sub-view target object corresponding to the sub-view identifier includes:
and in response to the fact that the size of the display part is larger than the preset threshold value, determining the rolling offset of the sub-view corresponding to the sub-view identifier based on the size of the display part, and further updating the attribute of the target object of the sub-view corresponding to the sub-view identifier. That is, based on the determined scroll offset of the sub-view corresponding to the sub-view identifier, it is determined whether the content display state of the sub-view is completely visible or partially visible or invisible, and if the content is partially visible, the size of the visible portion is determined, and accordingly, the attribute of the target object of the sub-view corresponding to the sub-view identifier at the current time (i.e., the scroll offset of the sub-view) is updated, and further, the content and the position of the corresponding sub-view are updated and displayed.
Step S103, an observation object is created, the observation object is added to serve as the correlation object of the parent view corresponding to the parent view identification based on the correlation object mechanism, and a callback mechanism is called to remove monitoring on the target object attribute of the parent view in response to the destruction of the observation object.
Specifically, the execution subject may add a self-defined AssociatedObject, that is, an observation object, to the parent view uisrolview object, and add the observation object as an association object of the parent view based on an association mechanism, so as to monitor whether a page corresponding to the parent view is closed and whether a page view resource is destroyed. When UIScrollView is destroyed, its associatedObject is also destroyed, and the remove KVO snoop is performed in the dealloc of the associatedObject. For example, the executing agent may add a class to the parent view for observing the destruction of the specified object, and issue a notification or callback when the specified object (i.e., the observed object) is destroyed. For example: the new class name is: jdobjectdeallocatch, where the add method: the WatchObjectDealloc. Calllback. the method contains two parameters: the first parameter WatchObject Delloc is an observed object; the second parameter callback is a callback function, which is the callback processing when the object is destroyed. Dealloc: the method executed when the object is destroyed, wherein the callback transmitted in the watchObjectDealloc callback is executed in the method. When the child view adds monitoring to the uisrolview, a jdobjectdeallocatch object may be created at the same time (this object is the associated object of the aforementioned uisrolview, and is used to obtain a destroy time of the uisrolview, and is used to remove KVO monitoring on the uisrolview when the uisrolview is destroyed, and when the uisrolview is destroyed, the associated object is also destroyed, and when the associated object is destroyed, a dealloc method is executed, and an execution subject may remove KVO monitoring of the uisrolview in the associated object dealloc), and call watchObjectDealloc: callback: the method introduces uisrolview and a callback for executing KVO removal. The execution body adds the created JDObjectDealloC Watcher object as an associated object of UIScrollView and specifies its memory policy as Retain. The Retain represents holding, and when the associated object is added to the uiScrollView, and the policy is used, the uiScrollView (i.e. the parent view) will Retain the holding relationship of the associated object, so as to ensure that the associated object exists during the existence of the UIScrollView.
Specifically, removing the snoops on the parent view target object attributes includes:
the execution subject determines that the parent view corresponding to the parent view identifier is destroyed in response to detecting that the preset callback function corresponding to the associated object is called, further destroys the associated object (for example, jdobjectdeallocatter), and removes the monitoring of the child view on the object attribute of the parent view.
In the embodiment of the application, Objective-C: a programming language is mainly used for developing application programs of an iOS system. KVO: key Value observer is a set of event notification mechanism. In the program it is allowed to listen for changes in a particular property of another object and to receive events when changed. Because of the implementation mechanism of KVO, actions only occur for attributes, and objects that are inherited from NSObject generally support KVO by default. And (4) classification: category, is a property of the Objective-c programming language that adds methods to existing classes. Uiscrillview: is a view that allows the view it contains to be scrolled or zoomed within its scope. Are parent classes of UITableView, UICollectionView, UITextView, etc. that also support scrolled views. ContentOffSet: is an attribute on the uiScrollView that represents the scroll offset of the UIScrollView. UIView: view objects, objects of screen-presented UI elements, manage the presentation of their content. NSObject: is the root class of object types in the Objective-C programming language type system, and all object types inherit the type. Association and object: namely, the related object is the characteristic that a plurality of objects can be related in Objective-C, and the purpose of dynamically adding attributes to the objects can be achieved. method swizzle: a mechanism that can replace the original method. dealloc: the system defaults to a method that executes an object when it is destroyed. The method can be rewritten in development so as to clean up related resources when the object is destroyed. Retain: an object reference management policy in object-C, representing strong references.
In the embodiment, a view processing request is received, and a corresponding sub-view identifier is acquired; determining a parent view identifier corresponding to the child view identifier, calling a monitoring mechanism according to the child view identifier and the parent view identifier to monitor a parent view target object attribute corresponding to the parent view identifier, and calling a callback mechanism to update a child view target object attribute corresponding to the child view identifier in response to determining that the parent view target object attribute changes; creating an observation object, adding the observation object as an association object of the parent view based on an association object mechanism, and calling a callback mechanism to remove monitoring on the target object attribute of the parent view in response to the destruction of the observation object. The child view is used for destroying and observing the target object attribute of the parent view, a wider rolling scene is supported, repeated work is less, code maintenance is simple, the accurate display state and the display part size of the child view can be obtained, and a universal solution capable of accurately acquiring the display state and the information of the list content in real time is provided.
Fig. 2 is a schematic main flow diagram of a view processing method according to a second embodiment of the present application, and as shown in fig. 2, the view processing method includes:
step S201, receiving a view processing request, and acquiring a corresponding sub-view identifier.
The principle of step S201 is similar to that of step S101, and is not described here.
Step S202, determining a parent view identifier corresponding to the child view identifier, calling a monitoring mechanism according to the child view identifier and the parent view identifier to monitor the parent view target object attribute corresponding to the parent view identifier, detecting the rolling offset of the parent view corresponding to the parent view identifier in real time, determining the parent view target object attribute change in response to the determined rolling offset, and calling a callback mechanism to update the child view target object attribute corresponding to the child view identifier in response to the determined parent view target object attribute change.
Specifically, the parent view uiscrillview is the most basic and most common scrolling view from which both UITableView and UICollectionView inherit. The contentOffset attribute in UIScrollView represents the scroll offset of the list. And converting and comparing the X or Y of the sub-view in the UIScrollView with the contentOffset to obtain the accurate display state and the size of the display part of the sub-view. KVO is an observer pattern feature by which the contentOffset attribute of the parent view uisrolview can be snooped, and any change that results in a contentOffset attribute can execute the relevant callback. The implementation manner of the embodiment of the application is divided into two parts: the KVO monitors the list to roll and calculate; KVO is removed. By detecting the rolling offset of the parent view corresponding to the parent view identifier in real time, when the rolling offset of the parent view is detected to be changed, the execution main body can determine that the attribute of the target object of the parent view is changed, so that the rolling offset of the approximate parent view is determined, and then the content display state of the child view and the relative position of the child view are calculated based on the rolling offset of the parent view, so that the child view is correspondingly displayed.
Step S203, an observation object is created, based on the associated object mechanism, the observation object is added to identify the associated object of the corresponding parent view for the parent view, and in response to the destruction of the observation object, a callback mechanism is called to remove the monitoring of the target object attribute of the parent view.
The principle of step S203 is similar to that of step S103, and is not described here.

The handler 302 in the processor creates an observed object 311, adds the observed object 311 to the associated object of the parent view 306 corresponding to the parent view identification 304 based on the associated object mechanism 312, and in response to the destruction of the observed object 311, invokes the callback mechanism 313 to remove the snoop to the parent view target object property 307.
