UIImagePickerController custom overlay and focus transition

Question

Is it possible to display the blue square of touching the focus when the user overlay is used in the UIImagePickerView and when the showCameraControl attribute is set to FALSE?

Answer 1

The modal view of the camera already supports touch focus. You must make your overlay look “transparent” for touch.

Subclass a UIView as an OverlayView and add something like this. In my overlay view, I have two buttons that, of course, should not be transparent to the touch.

- (BOOL)pointInside:(CGPoint)point withEvent:(UIEvent *)event {

    if (CGRectContainsPoint(infoButton.frame, point) || CGRectContainsPoint(snapButton.frame, point)) {
        // touched button
        return YES; 
    }

    return NO;
}
