获取滚动视图内的视图

Question

我有一个父滚动视图来显示pdf.Inside有视图。在视图中有另一个滚动视图进行缩放。在该滚动视图中有覆盖视图。我需要了解覆盖视图。我怎么才能得到它？

Answer 1

添加一个UIGestureRecognizer到覆盖视图。不要忘记确保视图的userActionEnabled属性设置为YES。

Answer 2

Make a new NSObject Class ScrollWithTouch and write following method inside .h and .m file: 
Code for .h file: 

@interface ScrollWithTouch : UIScrollView { 
} 
- (void) touchesEnded: (NSSet *) touches withEvent: (UIEvent *) event; 
-(id)initWithCustomScrollView; 
@end 

Code for .m file: 
#import "ScrollWithTouch.h" 


@implementation ScrollWithTouch 

-(id)initWithCustomScrollView{ 
    if (self = [super init]) { 

    } 
    return self; 
} 


- (void) touchesEnded: (NSSet *) touches withEvent: (UIEvent *) event 
{ 
    // If not dragging, send event to next responder 
    if (!self.dragging) 
     [self.nextResponder touchesEnded: touches withEvent:event]; 
    else 
     [super touchesEnded: touches withEvent: event]; 
} 
@end 

Now make a instance : 
ScrollWithTouch *tmpScrollView; 
tmpScrollView = [[ScrollWithTouch alloc] initWithCustomScrollView]; 

Add this new created object with your self.view; 
Now write touch related method within self.view. 
Assign tag for scroll view or assign tag for sub views on scroll view. 
Now you are ready to getting touch tag on tapping over scroll view.
