UILabel 在应用捏合手势时的文字模糊

Question

我正在使用 UIPinchGestureRecognizer 调整 UILabel 的大小，但也使用带有标签模糊的文本和捏合。 请帮忙。我正在使用以下代码来捏标签。

-(void)handlePinchGesture:(UIPinchGestureRecognizer *)pinchGesture
{
    float scale = pinchGesture.scale;
    UIView *view = (UIView *)pinchGesture.view;
    if ([view isMemberOfClass:[UILabel class]]) 
    {
         if (([pinchGesture state] == UIGestureRecognizerStateBegan || [pinchGesture state] == UIGestureRecognizerStateChanged))
         {           
                   [pinchGesture view].transform = CGAffineTransformScale([lbl transform],scale, scale);
                   [pinchGesture setScale:1];
         }
    }
}

看 iOS: Scaling UITextView with pinching?

- (void)scaleTextView:(UIPinchGestureRecognizer *)pinchGestRecognizer{
     CGFloat scale = pinchGestRecognizer.scale;

    createTextView.font = [UIFont fontWithName:createTextView.font.fontName size:createTextView.font.pointSize*scale];

    [self textViewDidChange:createTextView];       
}

希望对您有所帮助！让我知道这是否是您正在寻找的。​​p>

试试这个：

-(void)pinchLabel:(UIPinchGestureRecognizer *)recognizer{
CGFloat pinchScale = recognizer.scale;
_lblDouble.font = [UIFont systemFontOfSize:14.0*pinchScale];

}
