如何在多UIViews或UIImageViews的

Question

我不使用UIGestureRecognizers用於自來水，捏和旋轉;知道如何處理這個問題： -/

我只需要在圖像上添加標籤。應用程序將confeins貼紙喜歡錶情符號，心（圖像）選擇特定的貼紙它將被添加到主圖像和用戶可以操縱與貼紙，像他旋轉，縮放等，用戶可以選擇多個貼紙，並可以做旋轉縮放等添加貼紙，

請指導如何實現這一點，我能夠執行圖像maniuplation與單貼紙我不怎麼執行它的多個貼紙選擇，用戶可以再次回到任何貼紙，並執行操作。

您可以添加使用此方法的手勢：

- (void) addGestureRecognizers{ 
    UIPanGestureRecognizer *panRecognizer = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(move:)]; 
    [panRecognizer setMinimumNumberOfTouches:1]; 
    [panRecognizer setMaximumNumberOfTouches:1]; 
    [self addGestureRecognizer:panRecognizer]; 

    UIRotationGestureRecognizer *rotateRecognizer = [[UIRotationGestureRecognizer alloc] initWithTarget:self action:@selector(rotate:)]; 
    self.multipleTouchEnabled = YES; 
    [self addGestureRecognizer:rotateRecognizer]; 

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

    UILongPressGestureRecognizer *longPressRecognizer = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(longPressed:)]; 
    longPressRecognizer.minimumPressDuration = 2.0; 
    [self addGestureRecognizer:longPressRecognizer]; 
} 

和執行這些選擇：

- (void) move:(UIPanGestureRecognizer *)recognizer{ 
    CGPoint translation = [recognizer translationInView:self.superview]; 
    recognizer.view.center = CGPointMake(recognizer.view.center.x+translation.x, recognizer.view.center.y+translation.y); 
    [recognizer setTranslation:CGPointMake(0, 0) inView:self.superview]; 
} 

- (void) rotate:(UIRotationGestureRecognizer *)recognizer{ 
    NSLog(@"Rotate"); 
    recognizer.view.transform = CGAffineTransformRotate(
                 recognizer.view.transform, 
                 recognizer.rotation); 
    recognizer.rotation = 0; 
} 

- (void) pinch:(UIPinchGestureRecognizer *)recognizer{ 
    recognizer.view.transform = CGAffineTransformScale(recognizer.view.transform, recognizer.scale, recognizer.scale); 
    recognizer.scale = 1; 
} 

- (void) longPressed:(UILongPressGestureRecognizer *)recognizer{ 
    NSLog(@"Long Pressed"); 
} 

注意：只要你想

我期待當你particuler圖像單擊要執行對particuler肖像權有所行動，然後再嘗試這樣可能it'l幫助你

UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(imageTapped:)]; 

要添加手勢圖像視圖

...

- (void)imageTapped:(UITapGestureRecognizer *)sender 
{ 
    UIView *selectedView = sender.view; 
    //perform action here 

    or 

    sender.view.frame=newFrame;//you can set your frame 
} 

添加這一個用於同時手勢識別。

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer{ 
return YES: 
}
