Timestamped Event Matching Error: Failed to find matching element
提问by shay
I'm trying to generate a UItest in Xcode. When I try to swipe UIview I get an error:
我正在尝试在 Xcode 中生成一个 UItest。当我尝试滑动 UIview 时出现错误：
Timestamped Event Matching Error: Failed to find matching element
This also happens if I try to tap UIView.
如果我尝试点击 UIView，也会发生这种情况。

You should verify that the 'Accessibility' option is enabled for the UIView object you are swiping from, for example:
您应该验证是否为您正在滑动的 UIView 对象启用了“辅助功能”选项，例如：

Usually this issue is observed when the parent element of the element yo want to record is set to isAccessibilityElement=true. In general, you have to have the parent element set to false to access the child element. For example: if you have a UILabel inside a view, the accessibility should be set to false for the view and set to true for the UILabel.
通常，当您要记录的元素的父元素设置为 isAccessibilityElement=true 时，会观察到此问题。通常，您必须将父元素设置为 false 才能访问子元素。例如：如果视图中有 UILabel，则视图的可访问性应设置为 false，而 UILabel 的可访问性应设置为 true。

In Xcode 9.3, where this is apparently still a problem, what I did was:
在 Xcode 9.3 中，这显然仍然是一个问题，我所做的是：
- Quit Xcode
- Reset the Simulator's settings (Hardware -> Erase all contents and settings)
- Quit the Simulator
- Delete the derived data for the current app
- Restart Xcode
- Try recording again - it worked this time for me.
- 退出 Xcode
- 重置模拟器的设置（硬件 -> 擦除所有内容和设置）
- 退出模拟器
- 删除当前应用的派生数据
- 重启Xcode
- 再次尝试录制 - 这次对我有用。

I've been occasionally running into this problem. Delete the app's directory from DerivedData seems to help.
我偶尔会遇到这个问题。从 DerivedData 中删除应用程序的目录似乎有帮助。

For recording a new test, I don't think there's a solution yet. But, if you use an extension forcing tap with a test that already exists, works.
对于录制新测试，我认为目前还没有解决方案。但是，如果您将扩展强制点击与已存在的测试一起使用，则有效。
Example of use:
使用示例：
extension XCUIElement {
func forceTapElement() {
if self.hittable {
self.tap()
}
else {
let coordinate: XCUICoordinate = self.coordinateWithNormalizedOffset(CGVectorMake(0.0, 0.0))
coordinate.tap()
}
}
}
func testSomethingWithCells() {
let app = XCUIApplication()
let cells = app.tables.cells
sleep(1)
cells.elementBoundByIndex(0).forceTapElement()
}

A solution that worked for myself was to identify the object differently.
In Xcode 8 I was able to use the following:
一个对我有用的解决方案是以不同的方式识别对象。
在 Xcode 8 中，我能够使用以下内容：
XCUIApplication().tables.cells["Camera Roll"].buttons["Camera Roll"].tap()
With Xcode 9 I got the error mentioned in this question. Ended up using the following, which worked (al beit more flakey than the original option)
使用 Xcode 9 我得到了这个问题中提到的错误。最终使用了以下方法，该方法有效（尽管比原始选项更不稳定）
XCUIApplication().cells.element(boundBy: 1).tap()
