UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tapTapTap:)];
[self.view1 addGestureRecognizer:tapGesture];
[self.view2 addGestureRecognizer:tapGesture];
[tapGesture release];
在上面的代码中，只能识别view2上的点击。如果我注释掉第三行，那么点击view1会被识别。如果我是对的，你只能使用手势识别器一次，我不确定这是一个错误还是它只是需要一些更多的文档。

每次你添加一个指向相同func的手势识别器时，重写(重新创建)你的gesturerecogize。 在下面的情况下，它是有效的。我正在使用IBOutletCollection
斯威夫特2:
@IBOutlet var topicView: [UIView]!
override func viewDidLoad() {
for view in self.topicView as [UIView] {
view.addGestureRecognizer(UITapGestureRecognizer(target: self, action: "viewClicked:"))
}
}
func viewClicked(recognizer: UITapGestureRecognizer) {
print("tap")
}
其他回答
我们可以做一些像这样的事情，这很简单
1)在控制器中创建如下函数(此函数将返回GestureRecognizer)
-(UITapGestureRecognizer*)setRecognizer{
UITapGestureRecognizer *gestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(openProfile)];
[gestureRecognizer setNumberOfTapsRequired:1];
return gestureRecognizer;
}
2)现在在多个视图中设置这个识别器
[self.view1 addGestureRecognizer:[self setRecognizer]];
[self.view2 addGestureRecognizer:[self setRecognizer]];
对于Swift 3，如果有人需要这个: 基于Bhavik Rathod的回答。
func setGestureRecognizer() -> UIPanGestureRecognizer {
var panRecognizer = UIPanGestureRecognizer()
panRecognizer = UIPanGestureRecognizer (target: self, action: #selector(pan(panGesture:)))
panRecognizer.minimumNumberOfTouches = 1
panRecognizer.maximumNumberOfTouches = 1
return panRecognizer
}
///set the recognize in multiple views
view1.addGestureRecognizer(setGestureRecognizer())
view2.addGestureRecognizer(setGestureRecognizer())
UIGestureRecognizer用于单个视图。我同意文件是参差不齐的。UIGestureRecognizer只有一个视图属性，会泄露信息:
视图 手势识别器附加到的视图。(只读) @property(非原子，只读)UIView *view 你附加(或添加)一个手势识别器到一个UIView对象 使用addGestureRecognizer: 方法。
如果你有固定的视角，我建议你这样做
[self.view1 addGestureRecognizer:[[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tapTapTap:)]];
[self.view2 addGestureRecognizer:[[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tapTapTap:)]];
这样可以减少多个不同的无用变量
我使用下面的方法来解决这个问题。
for (UIButton *aButton in myButtons) {
UILongPressGestureRecognizer *longPress = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(handleLongPress:)];
longPress.minimumPressDuration=1.0;
[aButton addGestureRecognizer:longPress];
[longPress release];
}
然后在我的handleLongPress方法中，我只是设置一个UIButton等于手势识别器的视图，并根据该按钮分支我所做的事情
- (void)handleLongPress:(UILongPressGestureRecognizer*)gesture {
if ( gesture.state == UIGestureRecognizerStateEnded ) {
UIButton *whichButton=(UIButton *)[gesture view];
selectedButton=(UIButton *)[gesture view];
....
}
