objective-c - 响应UIControlEventTouchUpInside并触摸方法的按钮

我创建了一个按钮：

button = [StretchableButton new];
[button addTarget:mainViewController action:@selector(addNumberFromButton:) forControlEvents:UIControlEventTouchUpInside];

在StretchableButton类中，我具有：

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    [self.nextResponder touchesBegan:touches withEvent:event];
}

- (void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event {
    [self.nextResponder touchesMoved:touches withEvent:event];
}

- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {
    [self.nextResponder touchesEnded:touches withEvent:event];
}

调用了触摸方法，但是button不会对单击做出反应。

有谁能够帮助我？

最佳答案

添加手势识别器，代码示例：

    UIPanGestureRecognizer *gesturePan = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(pan:)];
    gesturePan.maximumNumberOfTouches = 1;
    gesturePan.minimumNumberOfTouches = 1;
    gesturePan.delegate = self;
    [myButton addGestureRecognizer:gesturePan];
    [gesturePan release];

....

- (void)pan:(UIPanGestureRecognizer *)gesture
{
    if ((gesture.state == UIGestureRecognizerStateChanged) ||
        (gesture.state == UIGestureRecognizerStateEnded)) {


    CGPoint location = [gesture locationInView:[gesture.view superView]];
//add calculation view location on it superview
    [gesture.view superView] setCenter:newLocation];

}
