您必须

在 initWithFrame 中使用 UIGestures （如果您使用 Interface Builder，则必须在 initWithCoder 中使用）

   UITapGestureRecognizer *doubleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(doubleTap:)];
    doubleTap.numberOfTapsRequired = 2;
    [self addGestureRecognizer:doubleTap];

    UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(singleTap:)];
    singleTap.numberOfTapsRequired = 1;
    [self addGestureRecognizer:singleTap];
    [singleTap requireGestureRecognizerToFail:doubleTap];

    [doubleTap release];
    [singleTap release];

然后添加方法

- (void) doubleTap: (UITapGestureRecognizer *) sender
{

     do whatever
}

- (void) singleTap:(UITapGestureRecognizer *)sender
{

}

You have to use UIGestures

In the initWithFrame (or initWithCoder if you're using Interface Builder)

   UITapGestureRecognizer *doubleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(doubleTap:)];
    doubleTap.numberOfTapsRequired = 2;
    [self addGestureRecognizer:doubleTap];

    UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(singleTap:)];
    singleTap.numberOfTapsRequired = 1;
    [self addGestureRecognizer:singleTap];
    [singleTap requireGestureRecognizerToFail:doubleTap];

    [doubleTap release];
    [singleTap release];

Then add the methods

- (void) doubleTap: (UITapGestureRecognizer *) sender
{

     do whatever
}

- (void) singleTap:(UITapGestureRecognizer *)sender
{

}

你需要使用手势，试试这个 -

UITapGestureRecognizer *doubleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(doubleTap:)];
    [doubleTap setNumberOfTapsRequired:2];
    [doubleTap setNumberOfTouchesRequired:1];
    [yourView addGestureRecognizer:doubleTap];
    [doubleTap release];

You need to use gestures, Try this -

UITapGestureRecognizer *doubleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(doubleTap:)];
    [doubleTap setNumberOfTapsRequired:2];
    [doubleTap setNumberOfTouchesRequired:1];
    [yourView addGestureRecognizer:doubleTap];
    [doubleTap release];

尝试在按钮定义中添加以下内容：-

[button addTarget:self action:@selector(buttontappedtwice)     forControlEvents:UIControlEventTouchDownRepeat];

其中，buttontappedtwice 是一个方法，当您点击此特定按钮两次时将调用该方法...干杯

Try adding following to button defination :-

[button addTarget:self action:@selector(buttontappedtwice)     forControlEvents:UIControlEventTouchDownRepeat];

where buttontappedtwice is a method which will be called when u tap this particular button twice... Cheers

试试这个。

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
     UITouch *touch = [[event allTouches] anyObject];
     if (touch.tapCount == 2) {
     }
}

Try this.

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
     UITouch *touch = [[event allTouches] anyObject];
     if (touch.tapCount == 2) {
     }
}
