如何以编程方式假冒触摸事件到UIButton? [英] how to programmatically fake a touch event to a UIButton?
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,我必须尽可能高地获得 UI
链。所以,我想要做的是以编程方式触发按钮按下,就像用户按下 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 - 我可以只是调用 IBAction
选择器,但同样,这个特定应用程序的性质重要的是我伪造实际按钮按下,这样就可以从按钮本身调用 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
事实证明
[buttonObj sendActionsForControlEvents: UIControlEventTouchUpInside];
在这种情况下,我得到了我所需要的。
got me exactly what I needed, in this case.
编辑: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)
