我如何在SuperView上獲取touchesBegan事件

Question

在我的程序中有兩個視圖（scrollView-super，view-sub * 2）。

在我的情況下，兩個子視圖在scrollView中被子視圖。 touchesBegan事件在子視圖中調用。

如何在scrollView中獲取事件？？？

@interface MyScrollView:UIScrollView
...
@implement MyScrollView
...
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    //here is my code
    //but I can't get event here
   ...
}
-(id)initWithFrame:(CGRect) frame
{
...
    MyView *view1 = [[MyView alloc] initWithFrame:(0, 0, 320, 240);
    MyView *view2 = [[Myview alloc] initWithFrame:(0, 240, 320,240);
    [self addSubview: view1];
    [self addSibvoew: view2];
...
}

@interface MyView:UIView
...
@implement MyScrollView
...
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
   //break points 
   //here comes event
}

Answer 1

試試這個代碼。

UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(singleTapGestureCaptured:)];

[scroll addGestureRecognizer:singleTap];

- (void)singleTapGestureCaptured:(UITapGestureRecognizer *)touch{
    CGPoint touchPoint=[gesture locationInView:scrollView]; 
    touchPoint = [touch locationInView:self.view];  
}

我建議將您的兩個子視圖設為全局，然后在超級視圖中使用touchesbegan方法將觸摸和事件傳遞給子視圖進行處理。 所以像[view1 touchesBegan：touches event：event]之類的東西； 我沒有測試過，但這應該是一種方法。
