The issue here is that you need to account for orientation when setting the center, so replace the line:

nav.view.superview.center = self.view.center;

with something like

UIDeviceOrientation orientation = ([[UIDevice currentDevice] orientation]);
const CGPoint centerPortait = self.view.center;
const CGPoint centerLandscape = CGPointMake(centerPortait.y, centerPortait.x);
const CGPoint center = (orientation == UIDeviceOrientationPortrait) ? centerPortait : centerLandscape;
nav.view.superview.center = center;

this will correctly center the modal view.
