UITableViewCell 中的 XCUIElement 层次结构 [英] XCUIElement hierarchy within UITableViewCell

问题描述

我在 UI 测试中遇到了一个奇怪的行为.当我将自定义视图添加到 UITableViewCell 时，它的某些子视图无法访问.但是，在 Xcode 的 Debug View Hierarchy 中是可以的.

I encountered a strange behaviour in UI-tests. When I add a custom view into UITableViewCell, some of it's subviews are not accessible. However, it's OK in Xcode's Debug View Hierarchy.

是的，我知道 UIAccessibilityContainer 但这不是解决方案的原因:1.我的自定义视图中有常规的子视图(视图、标签、图像)，而不是绘制的内容.2. 我不能为 containerView 禁用 isAccessibilityElement 并为 ImageView 启用它，因为我同时需要两者.

Yes, I know about UIAccessibilityContainer but it's not a solution cause of: 1. there are regular subviews in my custom view (views, labels, images), not a drawn content. 2. I can't disable isAccessibilityElement for containerView and enable it for ImageView cause of I need both in the same time.

因此，当我按原样将视图添加到 TableViewCell 时，我只能访问 UI 测试中的几个元素:

So, when I add my view to TableViewCell as-is, I can access only few elements from UI-tests:

Table, 0x604000196da0, traits: 35192962023424, {{5.0, 108.0}, {404.0, 586.0}}
  Cell, 0x604000384b90, traits: 8589934592, {{5.0, 132.0}, {365.0, 329.0}}
    StaticText, 0x6040003849f0, traits: 8589934656, {{9.0, 135.7}, {25.0, 12.7}}, identifier: 'myLabel', label: '123'
    StaticText, 0x604000384780, traits: 8589934656, {{73.0, 154.3}, {293.0, 18.7}}, identifier: 'titleLabel', label: 'Title'

如果我为图像启用 isAccessibilityElement，我也可以看到它:

If I enable isAccessibilityElement for images, I can see it as well:

Table, 0x604000196da0, traits: 35192962023424, {{5.0, 108.0}, {404.0, 586.0}}
  Cell, 0x604000384b90, traits: 8589934592, {{5.0, 132.0}, {365.0, 329.0}}
    Image, 0x604000384ac0, traits: 8589934596, {{9.0, 235.7}, {357.0, 174.3}}, identifier: 'myImage'
    StaticText, 0x6040003849f0, traits: 8589934656, {{9.0, 135.7}, {25.0, 12.7}}, identifier: 'myLabel', label: '123'
    StaticText, 0x604000384780, traits: 8589934656, {{73.0, 154.3}, {293.0, 18.7}}, identifier: 'titleLabel', label: 'Title'
    Image, 0x604000384370, traits: 8589934596, {{9.0, 156.3}, {56.0, 56.0}}, identifier: 'myIcon'

但是，在这两种情况下，Cell 内的层次结构都很简单，并且没有容器视图.

But, in both cases a hierarchy within Cell is plain and there are no container views.

推荐答案

解决方案是:使用 UICollectionView 而不是 UITableView.

这是一个正确的层次结构(isAccessibilityElement 对每个元素都有默认值).

Here is a correct hierarchy (isAccessibilityElement has default value for each element).
