UIScrollView的子類來檢測觸摸不靈

Question

我用這個代碼來檢測上的UIScrollView誰是UIView的

子

.h文件中

@interface AppScrollView : UIScrollView 
{ 
} 

@end 

.m文件

的頂部觸摸

#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 

然後在另一個班級我加

#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 

我也用過scroll1.delegate=self;但沒有任何反應！

任何人都可以幫助我嗎？

使用Gesture Recognizers。具體爲UITapGestureRecognizer。
