ios - iPad からのズームアウトとズームインの問題はありますか?

Question

iPadでズームアウトとズームイン機能を試してみる必要がありますが、うまく機能していますが、ズームの明瞭度は良くありません。それを知りませんでした。私を助けてください。

前もって感謝します

// This method will handle the PINCH / ZOOM gesture 
- (void)pinchZoom:(UIPinchGestureRecognizer *)gestureRecognizer
{
    if ([gestureRecognizer state] == UIGestureRecognizerStateBegan || [gestureRecognizer state] == UIGestureRecognizerStateChanged) {

        if (!zoomActive) {
            zoomActive = YES;

            UIPanGestureRecognizer *panGesture = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(panMove:)];
            [panGesture setMaximumNumberOfTouches:2];
            [panGesture setDelegate:self];
            [self addGestureRecognizer:panGesture];
            [panGesture release];

        }

        [gestureRecognizer view].transform = CGAffineTransformScale([[gestureRecognizer view] transform], [gestureRecognizer scale], [gestureRecognizer scale]);

        [delegate leavesView:self zoomingCurrentView:[gestureRecognizer scale]];            

        [gestureRecognizer setScale:1];


    }
