问题描述
我正在编写一些单元测试，并且由于这个特定应用程序的性质，重要的是我要在 UI 链中尽可能高.所以，我想做的是以编程方式触发按钮按下，就好像用户按下了 GUI 中的按钮一样.
I'm writing some unit tests and, because of the nature of this particular app, it's important that I get as high up the UI chain as possible. So, what I'd like to do is programmatically trigger a button-press, as if the user had pressed the button in the GUI.
(是的，是的——我可以只调用 IBAction 选择器，但同样，这个特定应用程序的性质使得我假装实际按下按钮很重要，以便从按钮本身调用 IBAction.)
(Yes, yes -- I could just call the IBAction selector but, again, the nature of this particular app makes it important that I fake the actual button press, such that the IBAction be called from the button, itself.)
这样做的首选方法是什么?
What's the preferred method of doing this?
推荐答案
原来如此
[buttonObj sendActionsForControlEvents:UIControlEventTouchUpInside];
在这种情况下，我得到了我需要的东西.
got me exactly what I needed, in this case.
不要忘记在主线程中执行此操作，以获得类似于用户按下的结果.
Don't forget to do this in the main thread, to get results similar to a user-press.
对于 Swift 3:
buttonObj.sendActions(for: .touchUpInside)
