UILongPressGestureRecognizer有不同的按钮

Question

我有2个按钮与 “UILongPressGestureRecognizer”，要做到这一点，我做的：

Fot的按钮1：

-(IBAction)seleccionar46:(id)sender{ 
UILongPressGestureRecognizer *longpressGesture =[[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(longPressHandler:)]; 
longpressGesture.minimumPressDuration = 3; 
[longpressGesture setDelegate:self]; 
[self.button1 addGestureRecognizer:longpressGesture];} 

对于按钮2：

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

而且在“longpressGesture”我需要区分button1和button2，但我不能这样做...

- (void)longPressHandler:(UILongPressGestureRecognizer *)gestureRecognizer{//Here i need do the differentation} 

谢谢大家！

此致敬礼。

你可以做的是使用UIGestureRecognizer的view属性，所以如果你保存对两个按钮的引用，你可以检查是否相等。

所以，如果你有

@interface blah 
{ 
    UIButton *buttonOne; 
    UIButton *buttonTwo; 
} 

那么你识别器添加到您可以在处理程序

if(gestureRecognizer.view==buttonOne) 
{ 
    //do stuff for button one 
} 
else if(gestureRecognizer.view==buttonTwo) 
{ 
    //do stuff for button two 
} 

希望它有助于
