objective-c - popToRootViewController 前进动画

Question

在我的库中，我有一个加载 View ，它会弹出到输入 View 。当用户完成输入 View 时，它应该返回加载 View 再次执行一些魔术，完成后它应该显示第三个 View 。

现在，从可用性 View 来看，我不想“滑回”到加载 View ，也不想在内存中已有加载 View 时分配新的加载 View 。

有什么方法可以在向前滑动 View 时弹出ToRootViewController？
(是的，我删除了加载 View 中的后退按钮)..

好的 - 也许尝试使用这样的东西

// This goes in whatever view controller you want to pop with
- (void)popToRootWithForwardAnimation
{
    NSMutableArray * viewControllers = [[[self.navigationController viewControllers] mutableCopy] autorelease]
    UIViewController * rootViewController = [viewControllers objectAtIndex:0]
    [viewControllers removeObjectAtIndex:0]; // try using with and without this line?
    [viewControllers addObject:rootViewController];

    [self.navigationController setViewControllers:viewControllers animated:YES];
}

// This goes in the root view controller
- (void)viewDidAppear:(BOOL)animated
{
    [super viewDidAppear:animated]
    NSMutableArray * viewControllers = [[[self.navigationController viewControllers] mutableCopy] autorelease]
    if ([viewControllers count] > 1)
    {
        [viewControllers removeAllObjects];
        [viewControllers addObject:self];

        [self.navigationController setViewControllers:viewControllers animated:NO];
    }

    … 
    …
}
