Turn off Zooming in UIScrollView

If you want to disable the user's ability to zoom through gestures then in iOS 5 and above you can disable the pinch gesture. This still allows you to control the scroll view from code...

scrollView.pinchGestureRecognizer.enabled = NO;

similarly for pan...

scrollView.panGestureRecognizer.enabled = NO;

This must be called in - (void)viewDidAppear:(BOOL)animated or later as otherwise the system resets it to enabled.

Swift 4.x and above:

imageZoomView.pinchGestureRecognizer?.isEnabled = false / true

Following fbrereto's advice above, I created two functions lockZoom and unlockZoom. When locking Zoom i copied my max and min zoom scales to variables then set the max and min zoom scale to 1.0. Unlocking zoom just reverses the process.

-(void)lockZoom{    maximumZoomScale = self.scrollView.maximumZoomScale;    minimumZoomScale = self.scrollView.minimumZoomScale;    self.scrollView.maximumZoomScale = 1.0;    self.scrollView.minimumZoomScale = 1.0;}-(void)unlockZoom{    self.scrollView.maximumZoomScale = maximumZoomScale;    self.scrollView.minimumZoomScale = minimumZoomScale;}

Also you can return "nil" as zooming view in UIScrollViewDelegate:

- (UIView *) viewForZoomingInScrollView:(UIScrollView *) scrollView{    return canZoom?view:nil;}
