TouchesBegan 仅在特定的 UIView 中开始
我有三个 UIView 实例：
UIView *view1;
UIView *view2;
UIView *view3;
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
UITouch *touch =[touches anyObject];
CGPoint startPoint =[touch locationInView:self.view];
}
但我希望 toch-action 只出现在 view2 中。如果我制作： locationInView:view2 则不起作用，
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
UITouch *touch =[touches anyObject];
CGPoint startPoint =[touch locationInView:view2];
}
我做错了什么？我如何检查哪个视图是我在 iPhone 上实际可以看到的视图？
I have three UIView instances:

UIView *view3;
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
UITouch *touch =[touches anyObject];
CGPoint startPoint =[touch locationInView:self.view];
}
But i want that the toch-action only go in view2. It doesnt work if i make: locationInView:view2
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
UITouch *touch =[touches anyObject];
CGPoint startPoint =[touch locationInView:view2];
}
What do I wrong? How can i check, which view is the view i actually can see on my iphone?

在您不希望处理触摸的视图中将 userInteractionEnabled 设置为 false。
set userInteractionEnabled to false in the view in which you don't want your touch to be handled.
