Background
In the use process of the intelligent device, jumping among view interfaces is basic operation for realizing the functions of the application program.
Currently, in the iOS system, jumping between view interfaces is implemented by stacking and popping View Controllers (VCs) by a Navigation Controller (Navigation Controller), wherein the Navigation Controller is a Controller that manages at least one VC in the form of a stack, the Navigation Controller is the Controller that controls the hierarchical relationship of jumping and returning between VCs, and the VC is the Controller responsible for managing the view hierarchy, and each VC manages one view hierarchy, including creating views in the view hierarchy and processing related user events, and adding the entire view hierarchy to an application window. Generally, in a navigation controller, a method for implementing a jump from a currently displayed VC to a target VC is as follows: and circularly traversing the target VC in the VC stack of the navigation controller, and realizing the operation of jumping from the current display VC to the target VC by calculating the hierarchical relationship between the current display VC and the target VC and performing pop-up operation.

The present disclosure is described in further detail below with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the disclosure and are not limiting of the disclosure. It should be further noted that, for the convenience of description, only some of the structures relevant to the present disclosure are shown in the drawings, not all of them. In the following embodiments, optional features and examples are provided in each embodiment, and various features described in the embodiments may be combined to form a plurality of alternatives, and each numbered embodiment should not be regarded as only one technical solution.
Example one
Fig. 1 is a flowchart of a rollback display processing method according to an embodiment of the present disclosure, where the present embodiment is applicable to a case of implementing interface skip or rollback, the method may be executed by a rollback display processing apparatus, the apparatus may be implemented in a software and/or hardware manner, and the apparatus may be configured in an electronic device, and typically, the electronic device is a smart phone, a tablet computer, and the like that are adapted to an iOS operating system. As shown in fig. 1, the method specifically includes the following steps:
The display task refers to a display task of an interface corresponding to a series of view levels when a complete function is realized, and comprises display and jump tasks at each level of view level. The task VC is a controller that manages all view hierarchies upon completion of the display task, and its main role is to create views in each view hierarchy and handle related user events, as well as to add the entire view hierarchy to the application window. The task VC comprises the following steps: the system comprises an initial layer VC, at least one transition layer VC and an end layer VC, wherein the initial layer VC manages a first layer view level of a display task, the end layer VC manages a last layer view level of the display task, and the at least one transition layer VC is arranged between the initial layer VC and the end layer VC and used for managing other view levels in the display task step by step so as to realize a complete function corresponding to the display task.
In a specific example, the complete function is a function that a user selects a commodity in a shopping cart interface in a shopping application and jumps back to the shopping cart interface after settlement payment, wherein an initial layer VC manages a shopping cart view level, an end layer VC manages a view level for prompting the user of successful payment, and a transition layer VC manages a settlement view level and a payment mode selection view level in the payment process.
In this embodiment, when it is determined that a display task corresponding to a complete function is to be processed, a corresponding VC stack, and an initial layer VC, at least one transition layer VC, and an end layer VC corresponding to the display task are first established in a navigation controller, and in a display process of the display task, the initial layer VC, the transition layer VC, and the end layer VC are called by the navigation controller according to an actual operation of a user, and display of a view level corresponding to a VC at the top of a stack in the VC stack is achieved by performing pop-up and pop-up operations in the VC stack.
And 120, assigning the identification information of the initial layer VC to the lower layer VC layer by layer in the display process of the display task.
The identification information of the initial layer VC is a name associated with the initial layer VC, and is used to form a corresponding relationship with the initial layer VC, that is, once the identification information appears in subsequent operations, a corresponding operation of calling the initial layer VC may be performed, for example, the identification information of the initial layer VC is defined as VC 1.
In this embodiment, when the navigation controller is triggered by actual operation of a user to call and display each layer of VC in the display process of the display task, the identification information of the initial layer of VC is assigned to the lower layer of VC layer by layer as the display task continues, that is, the identification information of the initial layer of VC is assigned to the lower layer of VC while the lower layer of VC is displayed, so as to form an association relationship between the lower layer of VC and the initial layer of VC.
The task ending response of the end layer VC is generally triggered by an event, for example, 5 seconds of stopping on the payment success interface is used as an event for triggering task ending response, and when the payment success interface corresponding to the end layer VC stops for 5 seconds, a task ending response for the end layer VC is sent out, where the task ending response is used to trigger a completion time callback attribute preconfigured in the end layer VC. The callback attribute is attribute information that is pre-configured in the end layer VC and used for triggering execution of a specified operation when a task ends, in this embodiment, the specified operation is: and in the execution process of the specified operation, acquiring identification information of the initial layer VC assigned layer by layer from the end layer VC by means of parameter calling and the like, specifically defining the target layer VC in the specified operation as the end layer VC, and finally executing the operation of returning the interface to the initial layer VC for display.
The present embodiment creates an initial layer VC corresponding to a display task, at least one transition layer VC and an end layer VC, and assigning the identification information of the initial layer VC to the lower layer VC layer by layer in the display process of the display task, when detecting the end task response aiming at the end layer VC, calling back the attribute when the end task response is configured in advance in the end layer VC, acquiring the identification information of the initial layer VC assigned layer by layer from the end layer VC, realizing the operation of returning the interface to the initial layer VC for displaying, that is, in this embodiment, the identification information of the initial layer VC is assigned to the lower layer VC layer by layer, so that the end layer VC does not need to perform complex hierarchical computation when returning to the initial layer VC, and only needs to trigger execution of the specified operation associated with the identification information of the initial layer VC through the preconfigured callback-on-completion attribute, so as to return the interface to the initial layer VC for display. The problem that in the prior art, when the hierarchical relationship between the end layer VC and the initial layer VC is calculated, the auxiliary judgment conditions are too many, the calculation mode is complex, the error rate of the result is high, and the final jump or rollback interface is not the interface corresponding to the initial layer VC is solved, and the effects of improving the accuracy and convenience of the rollback process are achieved.
Example two
Fig. 2 is a flowchart of a rollback display processing method according to a second embodiment of the present disclosure. This embodiment may be combined with each alternative in one or more of the above embodiments, and provides a specific execution step of assigning the identification information of the initial layer VC to the lower layer VC layer by layer in the display process of the display task. In the display process of the display task, the identification information of the initial layer VC is assigned to the lower layer VC layer by layer, which may be: if a view switching instruction entering a next-stage transition layer VC from an initial layer VC is detected, displaying the next-stage transition layer VC; and obtaining the identification information of the initial layer VC and assigning the identification information to the target parameter in the next-stage transition layer VC.
Alternatively, it may be: if a view switching instruction entering a next-stage second transition layer VC from the first transition layer VC is detected, displaying the second transition layer VC; acquiring a parameter value of a target parameter in a first transition layer VC as identification information of an initial layer VC; the parameter values are assigned to target parameters in the second transition layer VC.
Alternatively, it may be: if a view switching instruction for entering a next-level ending layer VC from a third transition layer VC is detected, displaying the ending layer VC; acquiring a parameter value of a target parameter in a third transition layer VC as identification information of an initial layer VC; the parameter values are assigned to target parameters in the end layer VC.
As shown in fig. 2, the method specifically includes the following steps:
In this embodiment, taking the example of uploading data in the cloud application, all technical solutions of this embodiment are described. In the cloud application, the display task is as follows: and when the progress in the uploading progress interface is 100%, skipping to an interface prompting the user to upload successfully, staying on the uploading successful interface for 5 seconds, and returning to the current uploading data list interface for the user to continuously upload data. The VC at the initial layer corresponds to a view level of an uploadable data list, the VC at the transition layer corresponds to a view level of a storage folder list and a view level of an uploading progress, and the VC at the ending layer corresponds to a view level for prompting a user to upload a view successfully.
And step 220, if a view switching instruction for entering the next-level transition layer VC from the initial layer VC is detected, displaying the next-level transition layer VC.
The view switching instruction is an instruction for triggering the navigation controller to call and display each layer of VC by actual operation of a user.
Continuing the specific example in the above steps, in the cloud application, after a user selects data to be uploaded through a current data list interface capable of uploading, clicking an icon corresponding to a function of selecting a storage position, triggering the navigation controller to send a view switching instruction for entering a next-level transition layer VC from an initial layer VC, and pressing a list view hierarchy of a storage folder into a VC stack for display through a stacking operation.
And step 230, obtaining the identification information of the initial layer VC and assigning the identification information to the target parameter in the next-stage transition layer VC.
Continuing the specific example in the above step, after the storage folder list interface is displayed, the navigation controller obtains identification information of the view level of the uploadable data list, and assigns the identification information to a target parameter of the view level of the storage folder list, where the target parameter is a variable parameter storing the identification information of the initial layer VC, and the target parameter exists in other layers of VCs except the initial layer VC.
And 240, if a view switching instruction for entering a next-level second transition layer VC from the first transition layer VC is detected, displaying the second transition layer VC.
In the above example, the first transition layer VC corresponds to a storage folder list view level, and the second transition layer VC corresponds to an upload progress view level.
Continuing the specific example in the above steps, in the cloud application, after a user selects a specific position for data uploading in the storage folder list interface, clicking an icon corresponding to the data uploading function, which triggers the navigation controller to send a view switching instruction for entering the second transition layer VC from the first transition layer VC, and through a stacking operation, pressing the uploading progress view level into the VC stack for display.
And step 250, acquiring a parameter value of a target parameter in the first transition layer VC as identification information of the initial layer VC.
Continuing the specific example in the above step, after the uploading progress interface is displayed, the navigation controller obtains the parameter value of the target parameter in the view level of the storage folder list, where the parameter value is the identification information of the initial layer VC.
And step 260, assigning the parameter value to the target parameter in the second transition layer VC.
Therefore, the identification information of the initial layer VC is assigned to the first transition layer VC from the initial layer VC, and then assigned to the second transition layer VC from the first transition layer VC.
In the above example, the third transition layer VC corresponds to an upload progress view level.
Continuing the specific example in the above steps, in the cloud application, when the progress in the uploading progress interface is 100%, triggering the navigation controller to send a view switching instruction entering from the third transition layer VC to the end layer VC, and pushing the view level prompting the user to successfully upload into the VC stack for display through the stacking operation.
And step 280, acquiring a parameter value of a target parameter in the third transition layer VC as the identification information of the initial layer VC.
Therefore, the process of assigning the identification information of the initial layer VC to the end layer VC layer by layer is realized.
In step 2100, if a task ending response for the end layer VC is detected, according to a pre-configured completion callback attribute in the end layer VC, acquiring identification information of the initial layer VC with value assigned layer by layer from the end layer VC, and returning the interface to the initial layer VC for display.
Continuing the specific example in the above step, in the cloud application, staying 5 seconds in the upload success interface as an event for triggering an end task response, and sending an end task response for the end layer VC after a prompt user corresponding to the end layer VC stays 5 seconds in the upload success view level, where the end task response is used for triggering an operation of returning the interface to the upload data list view level for display.
Optionally, obtaining, from the end layer VC, identification information of the initial layer VC that is assigned layer by layer according to a pre-configured post-completion callback attribute in the end layer VC, and returning the interface to the initial layer VC for display includes:
according to the attribute of callback when the interface is finished, executing a method for returning to a target VC, which is configured in advance in an end layer VC, so as to return the interface to an initial layer VC for display;
the target VC to be rolled back in the method for rolling back to the target VC is associated with the parameter value of the target parameter in the end layer VC.
The method for returning to the target VC may be a method for implementing the level jump, which is pre-packaged in the navigation controller, or a method for implementing the level jump, which is implemented by programming of a program developer.
In the optional technical scheme, the method for executing the fallback to the target VC is triggered by calling back the attribute when the method is completed, and when the method is executed, a specific parameter for determining the target VC needs to be called, and the specific parameter is associated with a parameter value of a target parameter in an end layer VC, so that the purpose that the target VC corresponds to an initial layer VC is achieved, thereby realizing the operation of displaying the interface fallback to the initial layer VC, improving the method for realizing the fallback to the target VC by calculating a hierarchical relationship in the prior art, greatly reducing the operation amount in the fallback display process, and improving the correctness of the fallback result.
For details, please refer to the foregoing embodiments, which are not described herein.
In the technical scheme, a specific execution step of assigning the identification information of the initial layer VC to the lower layer VC layer by layer in the display process of the display task is provided, so that the identification information of the initial layer VC can be accurately assigned to the lower layer VC until the identification information of the initial layer VC reaches the end layer VC, and an interface can be accurately returned to the initial layer VC for display.
