如何在UIButton中实现两个IBAction而不重叠？

I drag 2 IBA行动 from a UIButton，第一个是 touchDown 事件，第二个是拖动 Inside。

- (IBAction)clickButton:(UIButton *)sender {
    NSLog(@"Click Button");
}

- (IBAction)dragInsideButton:(UIButton *)sender {
    NSLog(@"Drag Button");
}

但是当我向内拖动时，touchDown 操作也会被触发。

如何在拖动时禁用 touchDown 事件。

Thanks!

我已经使用拖动事件解决了这样的问题

在 .xib 文件中或以编程方式将事件添加到按钮。

以编程方式是：

[mybut addTarget:self action:@selector(dragBegan:withEvent: )
  forControlEvents: UIControlEventTouchDown];
    [mybut addTarget:self action:@selector(dragMoving:withEvent: )
  forControlEvents: UIControlEventTouchDragInside];
    [mybut addTarget:self action:@selector(dragEnded:withEvent: )
  forControlEvents: UIControlEventTouchUpInside |
     UIControlEventTouchUpOutside];

事件的定义是：

- (void) dragBegan: (UIButton *) c withEvent:ev
{
    NSLog(@"dragBegan......");
    count=NO;//bool Value to decide the Down Event
    c.tag=0;
  [self performSelector:@selector(DownSelected:) withObject:mybut afterDelay:0.1];
 //user must begin dragging in 0.1 second else touchDownEvent happens

}

- (void) dragMoving: (UIButton *) c withEvent:ev
{
    NSLog(@"dragMoving..............");
    c.tag++;
}

- (void) dragEnded: (UIButton *) c withEvent:ev
{
    NSLog(@"dragEnded..............");
    if (c.tag>0 && !count)
    {

        NSLog(@"make drag events");

    }

}



-(void)DownSelected:(UIButton *)c
{
    if (c.tag==0) {
        NSLog(@"DownEvent");
        count=YES;//count made Yes To interrupt drag event
    }

}
