iOS - pop动画效果设置成类似push

为了防止重复跳转同个界面

CATransition *transition = [CATransition animation];
    transition.duration = 0.3f;
    transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseOut];
    transition.type = kCATransitionPush;
    transition.subtype = kCATransitionFromRight;
    [self.navigationController.view.layer addAnimation:transition forKey:nil];
    [self.navigationController popViewControllerAnimated:YES];
