Question

我希望在两个导航控制器之间进行自定义转换。我们先拨打sourceController，另一个detailNavController。

这是我的代码：

NewEntryViewController *viewController = [[NewEntryViewController alloc] 
                                                                  initWithStyle:UITableViewStyleGrouped];
viewController.parentController = self;

UINavigationController *detailNavController = [[UINavigationController alloc]
                                                                  initWithRootViewController:viewController];

[UIView beginAnimations:nil context:NULL];
[self.navigationController presentModalViewController:detailNavController animated:NO];

[UIView setAnimationDuration:0.4];
[UIView setAnimationTransition:UIViewAnimationTransitionCurlDown forView:sourceController.view cache:YES];

[UIView commitAnimations];

SourceController首先以模态方式呈现，这就是我以模态方式呈现detailNavController的原因。这段代码的问题在于动画发生了，但是sourceController仍然在新的detailNavController之上。我想要实现的是获取动画然后关闭sourceController并显示detailNavController。

我终于找到了解决方案，这里是更新后的代码：

- (void)createNewEntryWithAnimation
{
    // before calling this method I dismissed sourceController without animation
    NewEntryViewController *viewController = [[NewEntryViewController alloc] initWithStyle:UITableViewStyleGrouped];
    viewController.parentController = self;

    UINavigationController *detailNavController = [[UINavigationController alloc] 
                                                   initWithRootViewController:viewController];

    [UIView beginAnimations:nil context:NULL];
    [self.navigationController presentModalViewController:detailNavController animated:NO];

    [UIView setAnimationDuration:0.4];
    [UIView setAnimationTransition:UIViewAnimationTransitionCurlDown forView:viewController.view.window cache:NO];

    [UIView commitAnimations];
}

我不得不使用缓存：否，否则转换不顺畅。
