	- (void)viewDidLoad
	{
	 [super viewDidLoad];
	// Do any additional setup after loading the view.
	 self.flyView = [[UIView alloc] initWithFrame:CGRectMake(0, 200, 120, 60)];
	 self.flyView.layer.anchorPoint = CGPointMake(0.5, 1);
	 self.flyView.layer.position = CGPointMake(160, 200);
	 self.flyView.layer.transform = CATransform3DMakeRotation(M_PI, 0, 0, 1);
	 [self.flyView setBackgroundColor:[UIColor lightGrayColor]];
	 [self.view addSubview:self.flyView];
	
	
	 UIButton *showFly = [UIButton buttonWithType:UIButtonTypeCustom];
	 [showFly setFrame:CGRectMake(130, 300, 60, 40)];
	 [showFly setTitle:@"Fly" forState:UIControlStateNormal];
	 [showFly setBackgroundColor:[UIColor lightGrayColor]];
	 [showFly addTarget:self action:@selector(Fly:) forControlEvents:UIControlEventTouchUpInside];
	 [self.view addSubview:showFly];
	}
	
	- (void)Fly:(UIButton *)button
	{
	 switch (button.tag) {
	 case 0: {
	 [self showRoundMenu];
	 }
	 break;
	 case 1: {
	 [self hideRoundMenu];
	 }
	 break;
	 default:
	 break;
	 }
	
	 button.tag = button.tag == 0 ? 1 : 0;
	
	}
	
	- (void)showRoundMenu {
	 CABasicAnimation* ani = [CABasicAnimation animationWithKeyPath:@"transform"];
	 ani.duration = 0.6;
	 ani.autoreverses = NO;
	 ani.fillMode = kCAFillModeForwards;
	 ani.removedOnCompletion= NO;
	 ani.toValue = [NSValue valueWithCATransform3D:CATransform3DRotate(self.flyView.layer.transform, -M_PI, 0, 0, 1)];
	 [self.flyView.layer addAnimation:ani forKey:nil];
	}
	
	- (void)hideRoundMenu {
	 CABasicAnimation* ani = [CABasicAnimation animationWithKeyPath:@"transform"];
	 ani.duration = 0.6;
	 ani.autoreverses = NO;
	 ani.fillMode = kCAFillModeForwards;

	 ani.toValue = [NSValue valueWithCATransform3D:CATransform3DMakeRotation(M_PI, 0, 0, 1)];
	 [self.flyView.layer addAnimation:ani forKey:nil];
	}
