背景技术
在智能设备的使用过程中，视图界面间的跳转是实现应用程序功能的基础操作。
在iOS系统中，是以导航控制器(Navigation Controller)对视图控制器(ViewController，VC)进行压栈和出栈操作来实现视图界面间的跳转的，其中，导航控制器是以栈的形式管理至少一个VC的控制器，导航控制器最大的作用是控制VC之间的跳转以及返回的层级关系，VC是负责管理视图层次结构的控制器，每个VC管理一个视图层次结构，包括创建视图层级结构中的视图并处理相关用户事件，以及将整个视图层次结构添加到应用窗口。一般的，在导航控制器中，实现从当前显示VC跳转到目标VC的方法为：在导航控制器的VC栈中循环遍历目标VC，通过计算当前显示VC与目标VC间的层级关系以进行出栈操作，实现从当前显示VC跳转到目标VC的操作。
上述方法存在的缺点是：由于VC的复用操作会出现多个目标VC的副本，则在计算当前显示VC与目标VC间的层级关系时，需要增加大量的辅助判断条件，导致计算方式复杂且结果的错误率较高，使最终跳转或者回退的界面并不是目标VC对应的界面。

具体实施方式
下面结合附图和实施例对本公开进行说明。此处所描述的具体实施例仅仅用于解释本公开，而非对本公开的限定。为了便于描述，附图中仅示出了与本公开相关的部分而非全部结构。下述实施例中，每个实施例中同时提供了可选特征和示例，实施例中记载的多个特征可进行组合，形成多个可选方案，不应将每个编号的实施例仅视为一个技术方案。
实施例一
图1为本公开实施例一提供的一种回退显示处理方法的流程图，本实施例可适用于实现界面间跳转或者回退的情况，该方法可以由回退显示处理装置来执行，该装置可以采用软件和/或硬件的方式实现，该装置可以配置于电子设备中，该电子设备为适配iOS操作系统的智能手机、平板电脑等。如图1所示，该方法包括如下步骤：
步骤110、创建与显示任务对应的至少三层任务VC，至少三层任务VC依次包括：初始层VC、至少一个过渡层VC以及结束层VC。
本实施例中，显示任务是指实现一个完整功能时的一系列视图层级对应的界面的显示任务，包括在多级视图层级的显示以及跳转任务。至少三层任务VC是在完成显示任务时，管理所有视图层级结构的控制器，其主要作用是创建多个视图层级结构中的视图并处理相关用户事件，以及将整个视图层级结构添加到应用窗口。至少三层任务VC依次包括：初始层VC、至少一个过渡层VC以及结束层VC，其中，初始层VC管理的是显示任务的第一层视图层级，结束层VC管理的是显示任务的最后一层视图层级，在初始层VC和结束层VC之间，存在至少一个过渡层VC，用于逐级管理显示任务中的其他视图层级，以实现显示任务对应的完整功能。
在一个例子中，上述完整功能为用户在购物应用中，选择购物车界面中的商品，并在结算付款后跳转回购物车界面的功能，其中，初始层VC管理的是购物车视图层级，结束层VC管理的是提示用户付款成功的视图层级，过渡层VC管理的是在付款过程中的结算视图层级和选择付款方式视图层级等。
在本实施例中，当确定要处理一个完整功能对应的显示任务时，首先在导航控制器中建立对应的VC栈，以及与显示任务对应的初始层VC、至少一个过渡层VC以及结束层VC，在显示任务的显示过程中，初始层VC、过渡层VC以及结束层VC会根据用户的实际操作被导航控制器调用，通过在VC栈中进行出栈和入栈操作，实现对VC栈中栈顶的VC对应的视图层级的显示。
步骤120、在对显示任务的显示过程中，将初始层VC的标识信息逐层赋值 至下层VC中，其中，所述下层VC包括至少一个过渡层VC以及结束层VC。本实施例中，初始层VC的标识信息就是关联初始层VC的一个名称，用于和初始层VC形成对应关系，即在后续操作中一旦出现该标识信息，就可以执行对应的调用初始层VC的操作，例如，将初始层VC的标识信息定义为VC1。
在本实施例中，当在显示任务的显示过程中，用户的实际操作触发导航控制器对多层VC进行调用显示时，所述初始层VC的标识信息会随着显示任务的不断进行而被逐层赋值至下层VC中，即初始层VC的标识信息会在下层VC显示的同时，被赋值到下层VC中，形成下层VC与初始层VC的关联关系。
步骤130、在检测到针对结束层VC的结束任务响应的情况下，根据结束任务响应触发的在结束层VC中预先配置的完成时回调属性，从结束层VC中获取逐层赋值的初始层VC的标识信息，将界面回退至初始层VC进行显示。
本实施例中，结束层VC的结束任务响应一般由事件触发，例如，将在付款成功界面停留5秒作为触发结束任务响应的事件，当结束层VC对应的付款成功界面停留5秒后，会发出针对结束层VC的结束任务响应，该结束任务响应用于触发在结束层VC中预先配置的完成时回调属性。完成时回调属性是预先配置在结束层VC中的，用于在任务结束时，触发执行指定操作的属性信息，在本实施例中，所述指定操作为：界面回退至目标层VC进行显示，在所述指定操作执行过程中，会通过参数调用等手段从结束层VC中获取逐层赋值的初始层VC的标识信息，使所述指定操作中的目标层VC被定义为初始层VC，最终执行将界面回退至初始层VC进行显示的操作。
本实施例通过创建与显示任务对应的初始层VC、至少一个过渡层VC以及结束层VC，并在对显示任务的显示过程中，将初始层VC的标识信息逐层赋值至下层VC中，在检测到针对结束层VC的结束任务响应，根据结束任务响应触发的在结束层VC中预先配置的完成时回调属性，从结束层VC中获取逐层赋值的初始层VC的标识信息，实现将界面回退至初始层VC进行显示的操作，即本实施例通过将初始层VC的标识信息逐层赋值至下层VC中，使结束层VC在回退到初始层VC时无需进行复杂的层级计算，仅需要通过预先配置的完成时回调属性，触发执行与初始层VC的标识信息相关联的指定操作，即可将界面回退至初始层VC进行显示。解决了相关技术中，在计算结束层VC与初始层VC间的层级关系时，辅助判断条件过多，导致计算方式复杂且结果的错误率较高，使最终跳转或者回退的界面并不是初始层VC对应的界面的问题，实现了提高回退过程的准确性和便利性的效果。
实施例二
图2为本公开实施例二提供的一种回退显示处理方法的流程图。本实施例可以与上述一个或者多个实施例中可选方案结合，提供了在对显示任务的显示过程中，将初始层VC的标识信息逐层赋值至下层VC中的执行步骤。其中，在对显示任务的显示过程中，将初始层VC的标识信息逐层赋值至下层VC中，可以为：在检测到从初始层VC进入至下一级的过渡层VC的视图切换指令的情况下，对下一级的过渡层VC进行显示；获取初始层VC的标识信息并将初始层VC的标识信息赋值给下一级的过渡层VC中的目标参数。
或者，还可以为：在检测到从第一过渡层VC进入至下一级的第二过渡层VC的视图切换指令的情况下，对第二过渡层VC进行显示；获取第一过渡层VC中目标参数的参数值，其中，第一过渡层VC中目标参数的参数值为初始层VC的标识信息；将第一过渡层VC中目标参数的参数值赋值给第二过渡层VC中的目标参数。
或者，还可以为：在检测到从第三过渡层VC进入至下一级的结束层VC的视图切换指令的情况下，对结束层VC进行显示；获取第三过渡层VC中目标参数的参数值，其中，所述第三过渡层VC中目标参数的参数值为初始层VC的标识信息；将第三过渡层VC中目标参数的参数值赋值给结束层VC中的目标参数。
如图2所示，该方法包括如下步骤：
步骤210、创建与显示任务对应的至少三层任务VC，至少三层任务VC依次包括：初始层VC、至少一个过渡层VC以及结束层VC。
在本实施例中，以在云端应用中上传数据为例，说明本实施例的全部技术方案。在云端应用中，显示任务为：用户从当前可上传数据列表界面中选择待上传的数据，并在存储文件夹列表界面中选择数据上传的位置，当上传进度界面中的进度为100％后，跳转至提示用户上传成功界面，并在上传成功界面停留5秒后，回退至当前可上传数据列表界面，供用户继续上传数据。其中，初始层VC对应可上传数据列表视图层级，过渡层VC对应存储文件夹列表视图层级以及上传进度视图层级，结束层VC对应提示用户上传成功视图层级。
步骤220、在检测到从初始层VC进入至下一级的过渡层VC的视图切换指令的情况下，对下一级的过渡层VC进行显示。
本实施例中，视图切换指令即为用户的实际操作触发导航控制器对每层VC进行调用显示的指令。
延续上述步骤中的举例，在云端应用中，当用户通过当前可上传数据列表界面选择待上传的数据后，点击与选择存储位置功能对应的图标，该操作会触发导航控制器发出从初始层VC进入下一级的过渡层VC的视图切换指令，通过 入栈操作，将存储文件夹列表视图层级压入VC栈中，进行显示。
步骤230、获取初始层VC的标识信息并将初始层VC的标识信息赋值给下一级的过渡层VC中的目标参数。
延续上述步骤中的举例，当存储文件夹列表界面显示后，导航控制器获取可上传数据列表视图层级的标识信息，并将该标识信息赋值给存储文件夹列表视图层级的目标参数，其中，目标参数为存储初始层VC的标识信息的变量参数，目标参数存在于除初始层VC外的其他多层VC中。
步骤240、在检测到从第一过渡层VC进入至下一级的第二过渡层VC的视图切换指令的情况下，对第二过渡层VC进行显示。
本实施例中，第一过渡层VC和第二过渡层VC是对相邻的两个过渡层VC的统称，在上述步骤的举例中，第一过渡层VC对应存储文件夹列表视图层级，第二过渡层VC对应上传进度视图层级。
延续上述步骤中的举例，在云端应用中，当用户在存储文件夹列表界面中选择数据上传的位置后，点击与数据上传功能对应的图标，该操作会触发导航控制器发出从第一过渡层VC进入至第二过渡层VC的视图切换指令，通过入栈操作，将上传进度视图层级压入VC栈中，进行显示。
步骤250、获取第一过渡层VC中目标参数的参数值，其中，第一过渡层VC中目标参数的参数值为初始层VC的标识信息。
延续上述步骤中的举例，当上传进度界面显示后，导航控制器获取存储文件夹列表视图层级中目标参数的参数值，该参数值即为初始层VC的标识信息。
步骤260、将第一过渡层VC中目标参数的参数值赋值给第二过渡层VC中的目标参数。
至此，实现了初始层VC的标识信息从初始层VC赋值至第一过渡层VC，再从第一过渡层VC赋值至第二过渡层VC的过程。
步骤270、在检测到从第三过渡层VC进入至下一级的结束层VC的视图切换指令的情况下，对结束层VC进行显示。
本实施例中，第三过渡层VC是对临近结束层VC的过渡层VC的统称，在上述步骤的举例中，第三过渡层VC对应上传进度视图层级。
延续上述步骤中的举例，在云端应用中，当上传进度界面中的进度为100％后，触发导航控制器发出从第三过渡层VC进入至结束层VC的视图切换指令，通过入栈操作，将提示用户上传成功视图层级压入VC栈中，进行显示。
步骤280、获取第三过渡层VC中目标参数的参数值，其中，第三过渡层 VC中目标参数的参数值为初始层VC的标识信息。
步骤290、将第三过渡层VC中目标参数的参数值赋值给结束层VC中的目标参数。
至此，实现了将初始层VC的标识信息逐层赋值至结束层VC的过程。
步骤2100、在检测到针对结束层VC的结束任务响应的情况下，根据结束任务响应触发的在结束层VC中预先配置的完成时回调属性，从结束层VC中获取逐层赋值的初始层VC的标识信息，将界面回退至初始层VC进行显示。
延续上述步骤中的举例，在云端应用中，将在上传成功界面停留5秒作为触发结束任务响应的事件，当结束层VC对应的提示用户上传成功视图层级停留5秒后，会发出针对结束层VC的结束任务响应，该结束任务响应用于触发界面回退至可上传数据列表视图层级进行显示的操作。
可选的，根据结束任务响应触发的在结束层VC中预先配置的完成时回调属性，从结束层VC中获取逐层赋值的初始层VC的标识信息，将界面回退至初始层VC进行显示，包括：根据完成时回调属性，执行结束层VC中预先配置的回退至目标VC的方法，以将界面回退至初始层VC进行显示；其中，回退至目标VC的方法中的需要回退至的目标VC，与结束层VC中目标参数的参数值关联。
一实施例中，从结束层VC中获取逐层赋值的初始层VC的标识信息，将界面回退至初始层VC进行显示，包括：获取结束层VC中参数值为初始层VC的标识信息的目标参数，根据获取的初始层VC的标识信息将界面回退至初始层VC进行显示。
回退至目标VC的方法是可以在导航控制器中预先封装的，用于实现层级跳转的方法，也可以是程序开发人员编程实现的，用于实现层级跳转的方法。
在本可选的技术方案中，通过完成时回调属性触发执行回退至目标VC的方法，在该方法执行时，需要调用确定目标VC的参数，将该参数与结束层VC中目标参数的参数值关联，达到目标VC与初始层VC对应的目的，从而实现了将界面回退至初始层VC进行显示的操作，改进了相关技术通过计算层级关系实现回退至目标VC的方法，大大减少了回退显示过程中的运算量，并提高了回退结果的正确性。
本实施未解释之处，请参见前述实施例，在此不再赘述。
在上述技术方案中，提供了在对显示任务的显示过程中，将初始层VC的标识信息逐层赋值至下层VC中的执行步骤，保证了初始层VC的标识信息可以准确无误的被赋值至下层VC，直至结束层VC中，使界面可以准确的回退至初始层VC进行显示。
实施例三

可选的，赋值模块320，包括：第一显示单元，设置为在检测到从初始层VC进入至下一级的过渡层VC的视图切换指令的情况下，对下一级的过渡层VC进行显示；第一赋值单元，设置为获取初始层VC的标识信息并将初始层VC的标识信息赋值给下一级的过渡层VC中的目标参数。
可选的，赋值模块320，还包括：第二显示单元，设置为在检测到从第一过渡层VC进入至下一级的第二过渡层VC的视图切换指令的情况下，对第二过渡层VC进行显示；第一获取单元，设置为获取第一过渡层VC中目标参数的参数值，其中，第一过渡层VC中目标参数的参数值为初始层VC的标识信息；第二赋值单元，设置为将第一过渡层VC中目标参数的参数值赋值给第二过渡层VC中的目标参数。
可选的，赋值模块320，还包括：第三显示单元，设置为在检测到从第三过渡层VC进入至下一级的结束层VC的视图切换指令的情况下，对结束层VC进行显示；第二获取单元，设置为获取第三过渡层VC中目标参数的参数值，其中，第三过渡层VC中目标参数的参数值为初始层VC的标识信息；第三赋值单元，设置为将第三过渡层VC中目标参数的参数值赋值给结束层VC中的目标参数。
可选的，回退模块330，包括：回退单元，是设置为根据完成时回调属性，执行结束层VC中预先配置的回退至目标VC的方法，以将界面回退至初始层VC进行显示；其中，回退至目标VC的方法中的需要回退至的目标VC，与结束层VC中目标参数的参数值关联。
本实施例通过创建与显示任务对应的初始层VC、至少一个过渡层VC以及结束层VC，并在对显示任务的显示过程中，将初始层VC的标识信息逐层赋值至下层VC中，在检测到针对结束层VC的结束任务响应，根据结束任务响应触发的在结束层VC中预先配置的完成时回调属性，从结束层VC中获取逐层赋值的初始层VC的标识信息，实现将界面回退至初始层VC进行显示的操作，即本实施例通过将初始层VC的标识信息逐层赋值至下层VC中，使结束层VC在回退到初始层VC时无需进行复杂的层级计算，仅需要通过预先配置的完成时回调属性，触发执行与初始层VC的标识信息相关联的指定操作，即可将界面回退至初始层VC进行显示。解决了相关技术中，在计算结束层VC与初始层VC间的层级关系时，辅助判断条件过多，导致计算方式复杂且结果的错误率较高，使最终跳转或者回退的界面并不是初始层VC对应的界面的问题，实现了提高回退过程的准确性和便利性的效果。
