- (BOOL)shouldAutorotate

{

return YES;

}

-(BOOL) shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation

{

return (toInterfaceOrientation == UIInterfaceOrientationPortrait);

}

- (UIInterfaceOrientationMask)supportedInterfaceOrientations

{

return UIInterfaceOrientationMaskPortrait;

}
