Question

i used this code to detect touch on an uiscrollview who is on top of uiview

subclass

.h file

@interface AppScrollView : UIScrollView 
{
}

@end

.m file

#import "AppScrollView.h"

@implementation AppScrollView

- (id)initWithFrame:(CGRect)frame 
{
  return [super initWithFrame:frame];
}

- (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

and then on another class i added

#import <UIKit/UIKit.h>

@class AppScrollView;

@interface SomeClass : UIViewController <UIScrollViewDelegate>
{
  AppScrollView *scrollView;
  ...
}

@end

#import "AppScrollView.h"

@implementation SomeClass

...

- (void) touchesEnded: (NSSet *) touches withEvent: (UIEvent *) event 
{
  // Process the single tap here
  ...
}

...

@end

i used also scroll1.delegate=self; but nothing happens!!!

Can anyone help me?

Use Gesture Recognizers. Specifically UITapGestureRecognizer.
