iOS Pan手势

Question

我试图在平移时不要让我的平移手势垃圾邮件功能，它只在平移完成时播放一次功能，我已经在线看了所有并且找不到这样做的方法。有人有任何解决方案吗？

以下当前代码：

UIPanGestureRecognizer *panRecognizer = [[UIPanGestureRecognizer alloc] initWithTarget: self  action:@selector(didPan:)];
self.mapView.gestureRecognizers = @[panRecognizer];

- (void) didPan:(UIPanGestureRecognizer*) gestureRecognizer
{
    NSLog(@"DID PAN");
}

Answer 1

- (void)panGestureDetected:(UIPanGestureRecognizer*)panGesture {

    if(panGesture.state == UIGestureRecognizerStateEnded){
        //do whatever
    }
}

Answer 2

ViewController.h

@property（强，非原子）IBOutlet UIImageView * img;

ViewController.m

viewDidLoad

UIPanGestureRecognizer *panRecognizer = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(panDetected:)];

[_img addGestureRecognizer:panRecognizer];
