如何使这个复杂的动画重复和自动反转？有没有办法添加选项UIViewAnimationOptionAutoreverse | UIViewAnimationOptionRepeat到这个动画序列？

   [UIView animateWithDuration:1.0f animations:^{

        someView.frame = someFrame1;

    } completion:^(BOOL finished) {

        [UIView animateWithDuration:0.5f animations:^{

            someView.frame = someFrame2;

        } completion:nil];

    }];
