ios – UIView动画不起作用

我想在myView显示器上进行setTingView并使用动画消失.
我调用-showSetTingView
if(！self.setTingView)：动画正常工作.
但是,如果(self.myView)：setTingView消失WITHOUT动画.
如何修复它以使setTingView与动画一起消失？

@property (nonatomic,strong) UIView *myView;
@property (nonatomic,strong) UIView *setTingView;

- (void)viewDidLoad
{
    [super viewDidLoad];

    UIBarButtonItem* setTingButton = [[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemAction target:self action:@SELEctor(showSetTingView)];
    self.navigationItem.rightBarButtonItem = setTingButton;
}

- (void)showSetTingView
{
    self.myView = [[UIView alloc]initWithFrame:CGRectMake(0,568,320,480)];
    self.myView.opaque = NO;
    self.myView.BACkgroundColor = [UIColor colorWithWhite:1.0f alpha:0.0f];
    [self.view addSubview:self.myView];

    if (!self.setTingView) {
        self.setTingView = [[UIView alloc]initWithFrame:CGRectMake(0,568)];
        self.setTingView.BACkgroundColor = [UIColor blackColor];
        [self.myView addSubview:self.setTingView];
        [UIView animateWithDuration:0.3f
                              delay:0.0f
                            options:UIViewAnimationOptionTransitionFlipFromBottom
                         animations:^{self.myView.frame = CGRectMake(0,60,480);}
                         completion:^(BOOL finished) {}
         ];
    } else if (self.myView){
        self.myView.frame = CGRectMake(0,480);
        [UIView animateWithDuration:0.3f
                              delay:0.0f
                            options:UIViewAnimationOptionCurveEaseIn
                         animations:^{self.myView.frame = CGRectMake(0,480);}
                         completion:^(BOOL finished) {}
         ];
        [self.setTingView removeFromSuperview];
        self.setTingView = nil;
        [self.myView removeFromSuperview];
    }
}

谢谢.

                     animations:^{self.myView.frame = CGRectMake(0,480);}
                     completion:^(BOOL finished) {
                        [self.setTingView removeFromSuperview];
                        self.setTingView = nil;
                        [self.myView removeFromSuperview];
