Ios 如何在objective-c中访问UITAPPostation中的子视图控件？

朋友们好，请帮帮我， 我已经在UIWindow上添加了UIAPT手势，但我无法访问屏幕中的父控件

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];

uiRotationGestureRecognitzer*rot=[[uiRotationGestureRecognitzer alloc]initWithTarget:self action:@selector（HandlerRotation:）]；
rot.cancelsTouchesInView=否；
rot.delegate=self；
UIPinchGestureRecognizer*pinch=[[UIPinchGestureRecognizer alloc]initWithTarget:self
操作：@选择器（handlePinch:）]；
pinch.cancelsTouchesInView=否；
代表=自我；
/*UIPangestureRecognitor*pan=[[UIPangestureRecognitor alloc]initWithTarget:self
操作：@selector（handlePan:）]；
pan.cancelsTouchesInView=否；
pan.delegate=self*/
//圆圈手势
gr=[[MDCirclegestureRecognitor alloc]init]；
[gr addTarget:self action:@selector（HandleTesture:）]；
//[self.view addgestureRecognitor:gr]；
//gr.delegate=（id）self.view；
gr.代表=自我；
gr.cancelsTouchesInView=否；
////Z手势
cg=[[CharGesture alloc]initWithTarget:自我操作：@selector（zLetterMade:）]；
cg.代表=自我；
cg.cancelsTouchesInView=否；
//附加窗口-RR
[[[UIApplication sharedApplication]delegate]窗口]。手势识别器=@[gr、cg、pinch、rot]；

请确认您已给出

UIgestureRecognitizerDelegate

并启用交互

[[UIApplication sharedApplication]delegate]窗口].userInteractionEnabled=YES
