popViewControllerAnimated 动画在 iOS5 中不起作用

Question

尝试返回到之前的 viewController，但 iOS5 中的动画不起作用。

- (IBAction)backToPreviousController
{
    [self.navigationController popViewControllerAnimated:YES];
}

有人可以帮助我吗？

通过手动添加动画解决了问题

CATransition *transition = [CATransition animation]; 
transition.duration = 0.5; 
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionDefault]; 
transition.type = kCATransitionPush; 
transition.subtype = kCATransitionFromLeft; 
[self.navigationController.view.layer addAnimation:transition forKey:nil];
