I had a problem with :

CGAffineTransform trans = CGAffineTransformMakeRotation(M_PI_2);
slider.transform = trans;

because I had the code in ViewDidLoad method. Instead, I put the code in ViewDidAppear and it worked fine.

Edit: it doesn't have to be in the ViewDidAppear, ViewDidLoad works fine too (even better). You could disable auto-resize, or set a constraint for the slider you're rotating so the size doesn't change after rotation.
