UIlabel text alignment for ipad and iphone

Question

I am working on a universal app which has one label. When I rotate the screen, the label text alignment becomes different.

Answer 1

- (void) handleRotations:(UIRotationGestureRecognizer *)paramSender{
 if (self.helloWorldLabel == nil){
}
return;
/* Take the previous rotation and add the current rotation to it */
self.helloWorldLabel.transform = CGAffineTransformMakeRotation(self.rotationAngleInRadians +
paramSender.rotation);
/* At the end of the rotation, keep the angle for later use */ if (paramSender.state == UIGestureRecognizerStateEnded){
}
self.rotationAngleInRadians += paramSender.rotation;
