Question

我有一个带ScrollView SubView的ViewController，那些子视图中有一个子视图，下面是层次结构：

AppDelegate - MyViewController - ScrollView（来自xib） - MyScrollViewSubClass

// MyViewController： // .h

@interface MyViewController : UIViewController<MyScrollViewSubClassDelegate,UIScrollViewDelegate> {
    UIScrollView            *scrollView; // Loaded from xib 
}

@property(nonatomic,retain) IBOutlet UIScrollView *scrollView;

@end

// .m

@implementation MyViewController

@synthesize scrollView;

- (void)viewDidLoad {
    [super viewDidLoad];

    scrollView.delegate = self;

    MyScrollViewSubClass *myScrollView = [[MapScrollView alloc] init];
    myScrollView.delegate = self;
    myScrollView.myDelegate = self;

    scrollView addSubview:mapScrollView];
}

// The MyScrollViewSubClassDelegate @required method

- (void) onDoubleTapLocation: (CGPoint)tapPoint
{
    // Working,,,NSLog shown that this line is Working... 
}

// MyScrollViewSubClass + Delegate // .h

// Protocol
@protocol MyScrollViewSubClasswDelegate <NSObject>
@required
- (void) onDoubleTapLocation: (CGPoint)tapPoint;
@end

//Interface

@protocol MyScrollViewSubClass;

@interface MyScrollViewSubClass : UIScrollView <UIScrollViewDelegate> {
    id <MyScrollViewSubClasswDelegate> myDelegate;

    // Another vars..   
}

@property (nonatomic,assign) id<MyScrollViewSubClasswDelegate> myDelegate;

- (void)handleDoubleTap;

@end

// .m

@implementation MyScrollViewSubClass
@synthesize myDelegate;

- (id)initWithFrame:(CGRect)frame
{
    if ((self = [super initWithFrame:frame])) {

        // Another Code Here...

        self.delegate = self; // delegate for UIScrollView
        self.myDelegate = self;

        //Another Code Here...

    }
    return self;
}

- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
   if(isDoubleTap)
   {
      //Call handle double tap
      [self handleDoubleTap];
   }
}

- (void)handleDoubleTap {
    [self.myDelegate onDoubleTapLocation: tapLocation];
}

Happen是双击是在MyViewController上工作，但现在我无法从MyViewController滚动和捏缩我的MyScrollViewSubClass，欢迎任何评论家，评论或更好的方法..

已解决：

我在 MyViewController 上分配了两次委托

是：

myScrollView.delegate = self;
myScrollView.myDelegate = self;

应该是：

myScrollView.myDelegate = self;

问候，

其他一切运行良好......谢谢你们......

当我将触摸事件传递给superview时，MyScrollView不响应触摸
