uiscrollview 子类检测触摸不起作用

Question

我使用这段代码来检测位于 uiview

子类

.h 文件

@interface AppScrollView : UIScrollView 
{
}

@end

.m 文件

#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

之上的 uiscrollview 的触摸，然后在我添加的另一个类上

#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

我还使用了 scroll1.delegate=self; 但没有任何反应！ !!

谁能帮助我吗？

使用手势识别器< /a>.具体来说UITapGestureRecognizer。
