长按并单击按钮

Question

如何获取按钮单击单击或长按它点击事件？

Answer 1

检查这个代码

//Add Long Press Gesture Reconizer 
UILongPressGestureRecognizer *longPress = [[UILongPressGestureRecognizer alloc] 
             initWithTarget:self action:@selector(handleLongPress:)]; 
longPress.minimumPressDuration = 3; //seconds 
longPress.delegate = self; 
[yourButton addGestureRecognizer:longPress]; 

//Add button touch 
UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tapDetected:)]; 
tapGesture.numberOfTapsRequired = 1; 
tapGesture.numberOfTouchesRequired = 1; 
[yourButton addGestureRecognizer:tapGesture]; 
//For touch you can also set selector for button event with Controlevent touchupinside 


-(void) handleLongPress : (id)sender 
{ 
    //Long Press done by the user 
} 

-(void) tapDetected : (id) sender 
{ 
    //Button Tapped by user 
}

您可以使用NSTimer测量按钮上的“触摸内部”和“触摸内部”事件之间的持续时间。

然后，您将定义“长按”的阈值，并在长时间阈值已过时处理触摸事件作为“长按”。
