使用UIView animateWithDurationanimation时，不能触摸UIButton

我有以下代码： [UIView animateWithDuration:0.3 delay:0.0 options:UIViewAnimationCurveEaseOut | UIViewAnimationOptionAllowUserInteraction animations:^{ CGRect r = [btn frame]; r.origin.y -= 40; [btn setFrame: r]; } completion:^(BOOL done){ if(done){ [UIView animateWithDuration:0.3 delay:1 options:UIViewAnimationOptionCurveEaseIn | UIViewAnimationOptionAllowUserInteraction animations:^{ CGRect r = [btn frame]; r.origin.y += 40; [btn setFrame: r]; } completion:^(BOOL done){if(done) zombiePopping = 0; }]; } }]; 问题是，似乎button没有响应触摸animation时，即使我使用UIViewAnimationOptionAllowInteraction ，这是UIViewAnimationOptionAllowInteraction我。 也许这最核心的animation工作？ 如果是的话，我将如何去呢？
