tap/click view action Xcode
提问by ph3nx
is there a Touch Up Insidefor views?
I want to call an action when the user tap's or click's a view.
Currently I use a hidden button over this view, but thats not a smart way.
有Touch Up Inside意见吗？我想在用户点击或点击视图时调用一个动作。目前我在这个视图上使用了一个隐藏的按钮，但这不是一个聪明的方法。
Any help is appreciated :)
任何帮助表示赞赏:)

Well you can also use the addGestureRecognizer method on UIView like so:
那么你也可以像这样在 UIView 上使用 addGestureRecognizer 方法：
// In some View controller
UITapGestureRecognizer *tapGR;
tapGR = [[[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTap:)] autorelease];
tapGR.numberOfTapsRequired = 1;
[myUIView addGestureRecognizer:tapGR];
// Add a delegate method to handle the tap and do something with it.
-(void)handleTap:(UITapGestureRecognizer *)sender
{
if (sender.state == UIGestureRecognizerStateEnded) {
// handling code
}
}

I don't understand why using the hidden button would be not a smart way ... It is the suggested way by Apple itself, i think it is smart and the better way at the moment ...
我不明白为什么使用隐藏按钮不是一种聪明的方式......这是Apple本身建议的方式，我认为它是明智的并且目前更好的方式......

Use - (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)eventif you are looking to detect touches anywhere on the screen with no buttons. You can also find the location of the touch like so:
使用- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event，如果你正在寻找任何地方发现没有按钮的触摸屏上。您还可以像这样找到触摸的位置：
- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {
UITouch *touch = [touches anyObject];
CGPoint *tLocation = [touch locationInView:self.view];
}
Note: touchesEndedis called EVERY SINGLE TIMEthe view is tapped, so the above tLocationwill change every time the user touches the screen.
注意：touchesEnded被称为EVERY SINGLE TIME视图被点击，因此tLocation每次用户触摸屏幕时上述内容都会改变。
