我有两个带"UILongPressGestureRecognizer"的按钮,为此,我这样做:
Fot按钮1:
-(IBAction)seleccionar46:(id)sender{
UILongPressGestureRecognizer *longpressGesture =[[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(longPressHandler:)];
longpressGesture.minimumPressDuration = 3;
[longpressGesture setDelegate:self];
[self.button1 addGestureRecognizer:longpressGesture];}

-(IBAction)seleccionar46:(id)sender{
UILongPressGestureRecognizer *longpressGesture =[[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(longPressHandler:)];
longpressGesture.minimumPressDuration = 3;
[longpressGesture setDelegate:self];
[self.button2 addGestureRecognizer:longpressGesture];}
