How to disable zoom and keep controls on UIImagePickerController?

I would like to use UIImagePickerController to take pictures and disabling the use of the zoom pinch function while not blocking the camera controls when I do a [picker addSubView:myOverlay]. So I create the following "myOverlayView" class with the hope of intercepting all touches so that my UIImagePickerController camera controls are not affected.

(per this tutorial: https://josee.me/2011/02/16/overlaying-the-iphone-camera-without-blocking-its-controls/)

// implement UIView Class...
@implementation myOverlayView : UIView

- (id)initWithFrame:(CGRect)frame {
    if (self = [super initWithFrame:frame]) {
        self.opaque = NO;
        self.backgroundColor = [UIColor clearColor];
    }
    return self;
}

- (BOOL)hitTest:(CGPoint)point withEvent:(UIEvent *)event {
    NSLog(@"hitTest....hit");
    return nil;
}

@end

// Call Camera...
picker.delegate = self;
picker.allowsEditing = NO;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;

myOverlayView *myOverlayView1 = [[myOverlayView alloc]init];

[picker.view addSubview:myOverlayView1];


[self presentViewController:picker animated:YES completion:NULL];

The hitTest:Event method gets hit and the zoom pinch still works after the overlay has been added. What am I missing?

Why don't you try the following: Add a UIPinchGestureRecognizer to your overlay, and set the *pinchGesture.cancelsTouchesInView = YES? Haven't tried this, but should be able to intercept the pinching of the picker.
