1.1 點(diǎn)擊手勢

//輕觸 彩蛋
UITapGestureRecognizer* tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tap:)];

//觸摸次數(shù)
tap.numberOfTapsRequired = 2;

//觸摸點(diǎn)數(shù)量 
//tap.numberOfTouchesRequired = 2;

[imageView addGestureRecognizer:tap];

1.2 長按手勢

UILongPressGestureRecognizer* longPress = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(longPress:)];

[imageView addGestureRecognizer:longPress];


//長按事件
- (void)longPress:(UILongPressGestureRecognizer*)longPress{
    
    if (longPress.state == UIGestureRecognizerStateBegan) {
        
        NSLog(@"開始長按");
        
    }
    
    if (longPress.state == UIGestureRecognizerStateChanged) {
        
        NSLog(@"長按中");
        
    }
    
    if (longPress.state == UIGestureRecognizerStateEnded) {
        
        NSLog(@"長按結(jié)束");
        
    }
    
}

1.3 移動手勢

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

[imageView addGestureRecognizer:pan];


//移動事件
- (void)pan:(UIPanGestureRecognizer*)pan{
    
    CGPoint point = [pan translationInView:self.view];
    
    imageView.center = CGPointMake(imageView.center.x + point.x, imageView.center.y + point.y);
    
    //以當(dāng)前點(diǎn)為原點(diǎn)計(jì)算
    
    [pan setTranslation:CGPointZero inView:self.view];
    
}

1.4 旋轉(zhuǎn)手勢

UIRotationGestureRecognizer* rotation = [[UIRotationGestureRecognizer alloc] initWithTarget:self action:@selector(rotation:)];

rotation.delegate=self;

[imageView addGestureRecognizer:rotation];


- (void)rotation:(UIRotationGestureRecognizer*)rotation{
    
    _imageView.transform = CGAffineTransformMakeRotation(_rotation + rotation.rotation);
    
    if (rotation.state == UIGestureRecognizerStateEnded) {
        
        _rotation += rotation.rotation;
        
    }
    
}

1.5 縮放手勢

UIPinchGestureRecognizer* pinch = [[UIPinchGestureRecognizer alloc] initWithTarget:self action:@selector(pinch:)];

pinch.delegate=self;

[imageView addGestureRecognizer:pinch];


- (void)pinch:(UIPinchGestureRecognizer*)pinch{
    
    //1.1 1.1
    _imageView.bounds = CGRectMake(0, 0, _imageView.bounds.size.width * pinch.scale, _imageView.bounds.size.height * pinch.scale);
    
    [pinch setScale:1];
    
}

1.6 方向滑動手勢

需要分開寫
self.leftSwipeGestureRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipes:)];
self.rightSwipeGestureRecognizer = [[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(handleSwipes:)];

self.leftSwipeGestureRecognizer.direction = UISwipeGestureRecognizerDirectionLeft;
self.rightSwipeGestureRecognizer.direction = UISwipeGestureRecognizerDirectionRight;

[self.view addGestureRecognizer:self.leftSwipeGestureRecognizer];
[self.view addGestureRecognizer:self.rightSwipeGestureRecognizer];


- (void)handleSwipes:(UISwipeGestureRecognizer *)sender
{
    if (sender.direction == UISwipeGestureRecognizerDirectionLeft) {
        
    }
    
    if (sender.direction == UISwipeGestureRecognizerDirectionRight) {
        
    }
}
