UI Testing Xcode 7- can't access element within subview
提问by sebradloff
I'm trying to access an element within a subview and I'm finding it impossible to do so.
我正在尝试访问子视图中的元素，但我发现这是不可能的。
The hierarchy being:
层次结构是：
View Controller:
视图控制器：
- View
- tempView
- userEnterView
- zipCodeEntered
- 看法
- 临时视图
- 用户输入视图
- 邮政编码输入
I want to access the zipCodeEntered text field. I have an accessibility label on it named "zipCodeEntered".
我想访问 zipCodeEntered 文本字段。我有一个名为“zipCodeEntered”的可访问性标签。
When I try and record the automation, it only register the superview "userEnterView" and not the actual text field which I can tap into.
当我尝试记录自动化时，它只注册超级视图“userEnterView”，而不是我可以利用的实际文本字段。
I print "app.otherElements[SUPER_VIEW_NAME].debugDescription" to see what elements are in that hierarchy and it prints none.
我打印“app.otherElements[SUPER_VIEW_NAME].debugDescription”以查看该层次结构中的元素，但它不打印任何元素。
Any ideas as to why I can not access these elements/how I can access them?
关于为什么我无法访问这些元素/如何访问它们的任何想法？

The subviews are not accessible because the parent view is not a container view. From the section Making Your iOS App Accessiblefrom the Accessibility Programming Guide:
子视图不可访问，因为父视图不是容器视图。来自可访问性编程指南中的“使您的 iOS 应用程序可访问”部分：
From the perspective of accessibility, a custom view is either an individual view or a container view. An individual view does not contain any other views that need to be accessible.
A container view, on the other hand, contains other elements with which users can interact.
从可访问性的角度来看，自定义视图要么是单个视图，要么是容器视图。单个视图不包含任何其他需要访问的视图。
另一方面，容器视图包含用户可以与之交互的其他元素。
To make the subviews accessible the parent view should tell UIAccessibilitythat it is an accessibility container by returning NO from -isAccessibilityElementand implementing the methods of the UIAccessibilityContainerprotocol.
为了使子视图可访问，父视图应该UIAccessibility通过返回 NO-isAccessibilityElement并实现UIAccessibilityContainer协议的方法来告诉它是一个可访问性容器。

The thing that fixed it for me was to check √ the "Accessibility" box to enabled in Interface Builder.
为我修复它的事情是选中 √ 在 Interface Builder 中启用的“辅助功能”框。
If not working in IB try setting the the view's isAccessibilityElementproperty to true.
如果不在 IB 中工作，请尝试将视图的isAccessibilityElement属性设置为 true。
Hope that helps!
希望有帮助！

I also encountered this problem in my UITableView. My cell has a containerView(UIView) which has subviews(TextView, UIButton...) and a collectionView with its cells.
我在 UITableView 中也遇到过这个问题。我的单元格有一个 containerView(UIView)，它有 subviews(TextView, UIButton...) 和一个带有单元格的 collectionView。
I tried the accepted answer, but it didn't work.(UI Recorder or manual code didn't recognize my sub-elements). But sometimes I found the UITest suddenly recognized my sub-elements when I triggered something to refresh the table.
我尝试了接受的答案，但没有奏效。（UI Recorder 或手动代码无法识别我的子元素）。但有时我发现当我触发某些东西刷新表格时，UITest 会突然识别出我的子元素。
So right now I know if UITest can't find my subviews, I invoke tableView.reloadDatato refresh the view, and then all the problem is gone.
所以现在我知道如果 UITest 找不到我的子视图，我调用tableView.reloadData刷新视图，然后所有问题都消失了。
Anyway, this is just a workaround, I hope Apple can fix it as soon as possible.
无论如何，这只是一种解决方法，我希望苹果能够尽快修复它。
