你尝试过什么来找到它？不过...你可以从这里开始：UILongPressGestureRecognizer类参考。 - holex

点击？你用鼠标吗？ - Fogmeister

Answer 1

请检查这段代码

//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
}

点击？什么是点击？鼠标？ - Fogmeister

点击被视为触摸。我已经修改为触摸。 - ipraba

Answer 2

你可以使用NSTimer来测量按钮的“touch down inside”和“touch up inside”事件之间的持续时间。

然后，您将定义一个“长按”阈值，并在持续时间阈值已过时处理触摸事件作为“长按”。

能否请您将代码放在那里，没有“touch down inside”这个方法，而是“touch down”。 - Nims
