Question

I want to open camera with animation effect, so that it should appear that camera is opening in the parent screen only.
I am using camera overlay screen and on click event of button in parent screen,camera overlay screen is opening,in camera overlay screen there is a cancel button to close the camera,so while closing the camera again I need to show the animation effect that it should appear that now camera is closed in the same parent scree.
I have tried kCATransitionMoveIn but not fully satisfied,if any once has better solution please help me.

CATransition * contentAnimation = [CATransition animation];
    contentAnimation.type = kCATransitionMoveIn;
    contentAnimation.subtype = kCATransitionFromBottom;
    contentAnimation.duration = 1.0;
    contentAnimation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseOut];
    [[self.view layer] addAnimation:contentAnimation forKey:kCATransition];
    //self.view.hidden = YES;
    [CATransaction commit];
    // Show the scanner overlay
    [self presentModalViewController:overlayController.parentPicker animated:TRUE];
