[英]Long press and single click on button
如何获得按钮单击一次或长按它点击事件?
检查此代码
//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来测量按钮上的“内部触摸”和“内部触摸”事件之间的持续时间。
然后,您将为“长按”定义阈值,并在持续时间阈值已通过时将触摸事件处理为“长按”。
