在视图控制器之间移动时动画不会重新启动

Question

我有许多动画在加载我的根视图控制器时自动启动.这些动画包括在内viewDidLoad.当我导航到我的下一个视图控制器并返回到根视图控制器时,所有动画都已停止.当我按下"主页"按钮然后返回到视图时,会出现相同的行为.

我敢肯定我在这里遗漏了一些非常基本的东西但是会感激任何帮助.谢谢.

编辑1:

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    [self beeBobbing];
    //animate the butterfly oscillating
    [self butterflyOscillate];

}

-(void) beeBobbing
{
    [UIView animateWithDuration:1.0f delay:0 options:(UIViewAnimationOptionCurveEaseInOut | UIViewAnimationOptionRepeat | UIViewAnimationOptionAutoreverse | UIViewAnimationOptionAllowUserInteraction ) animations:^{
        CGPoint bottomPoint = CGPointMake(215.0, 380.0);
        imgBee.center = bottomPoint;
    } completion:^(BOOL finished) {

    }];

}

编辑2:在视图之间切换时,这种类型的动画似乎重新启动:

-(void) animateClouds
{
    [UIView animateWithDuration:30.0f delay:0 options:UIViewAnimationOptionCurveLinear animations:^{
        CGPoint leftScreenCenter = CGPointMake(-420.0, 119.0);
        imgClouds.center = leftScreenCenter;
    } completion:^(BOOL finished) {
        CGPoint rightScreenCenter = CGPointMake(1450.0, 119.0);
        imgClouds.center = rightScreenCenter;
        [UIView animateWithDuration:40.0f delay:0 options: (UIViewAnimationOptionCurveLinear | UIViewAnimationOptionRepeat) animations:^{
            CGPoint leftScreenCenter = CGPointMake(-420.0, 119.0);
            imgClouds.center = leftScreenCenter;
        } completion:^(BOOL finished) {

        }];

    }];

}

我想如果你把所有的动画都给viewWillAppear:它的工作很好......就是这样...... :)
