I do the following to a loading animation, to place it at the bottom center of the screen.
CGPoint bottomCenter = CGPointMake((self.imageView.bounds.size.width / 2), (self.imageView.bounds.size.height * 0.8));
self.activityView.center = bottomCenter;
(imageView is the full screen splash image)
If the orientation is portrait, it is positioned perfectly, however turning on its side, in landscape or upside down portrait and the animation ends up miles away :S
Does anyone know the correct way to position this loading animation, its for the splash screen.
