iOS 自动，手动 屏幕翻转

屏幕翻转方案：

手动翻转：按钮触发：

- (IBAction)totate:(id)sender {

    

    [[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeRight];

    self.view.transform = CGAffineTransformMakeRotation(M_PI/2);

    self.view.bounds = CGRectMake(0, 0, 480, 320);

    

}

- (BOOL)shouldAutorotate

{

    return NO;

}

- (NSUInteger) supportedInterfaceOrientations{

    return  UIInterfaceOrientationMaskLandscapeRight ;

}

自动翻转：

- (BOOL)shouldAutorotate

{

    return YES;

}

- (NSUInteger) supportedInterfaceOrientations{

    return  UIInterfaceOrientationMaskLandscapeRight ;

}
