多个UIView如何知道touchesBegan监听点击的是哪个View

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)eventViewController中有多个UIView和一个ScrollViewScrollView重新了touchesBegan事件现在我如何知道touche的是uiview还是scrollview呢？

Answer 1

最上层的view首先截获到touchbegan事件。

Answer 2

UITouch *touch = [touches anyObject];UIView *view = [touch view];

Answer 3

uiview有一个方法，可以把触摸强制交给某个view处理- (UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event;
