有没有办法来调用多个UIControlEvents选择？
这并不工作，但itl'll作罢什么，我试图做一个想法。
[self.slider addTarget:self action:@selector(sliderDidStopDragging:) forControlEvents:UIControlEventTouchUpInside, UIControlEventTouchUpOutside];
谢谢！！
Answer 1:
尝试这种方式来代替：
// same selector for different events
[self.button addTarget:self action:@selector(selector0:) forControlEvents:UIControlEventTouchUpInside];
[self.button addTarget:self action:@selector(selector0:) forControlEvents:UIControlEventTouchUpOutside];
// etc...
或者你可以使用这个：
// different selectors for same event
[self.button addTarget:self action:@selector(selector1:) forControlEvents:UIControlEventTouchUpInside];
[self.button addTarget:self action:@selector(selector2:) forControlEvents:UIControlEventTouchUpInside];
// etc...
Answer 2:
只要OR它们：
[self.button addTarget:self action:@selector(selector0:) forControlEvents:(UIControlEventTouchUpInside|UIControlEventTouchUpOutside)];
