如何在objective-c中访问UITapGesture中的子视图控件？

Question

朋友你好，请帮我，我 添加UITapGesture上的UIWindow，但我不能在屏幕上能够访问父控件

UIRotationGestureRecognizer *rot =[[UIRotationGestureRecognizer alloc] initWithTarget:self action:@selector(handleRotation:)]; 

rot.cancelsTouchesInView = NO; 
rot.delegate = self; 
UIPinchGestureRecognizer *pinch =[[UIPinchGestureRecognizer alloc] initWithTarget:self 
action:@selector(handlePinch:)]; 
pinch.cancelsTouchesInView = NO; 
pinch.delegate = self; 
/* UIPanGestureRecognizer *pan = [[UIPanGestureRecognizer alloc] initWithTarget:self 
action:@selector(handlePan:)]; 
pan.cancelsTouchesInView = NO; 
pan.delegate = self;*/ 


//circle gesture 
gr = [[MDCircleGestureRecognizer alloc] init]; 
[gr addTarget:self action:@selector(handleGesture:)]; 
//[self.view addGestureRecognizer:gr]; 
//gr.delegate = (id<MDCircleGestureFailureDelegate>)self.view; 
gr.delegate = self; 
gr.cancelsTouchesInView = NO; 

////Z gesture 
cg = [[CharGesture alloc] initWithTarget:self action:@selector(zLetterMade:)]; 
cg.delegate=self; 
cg.cancelsTouchesInView = NO; 
//Add on window - RR 
[[[UIApplication sharedApplication]delegate]window].gestureRecognizers = @[gr,cg,pinch,rot];

请确认你已经给UIGestureRecognizerDelegate并启用互动[[[UIApplication sharedApplication]delegate]window].userInteractionEnabled=YES;
