“开始/结束外观转换的不平衡调用"在带有 Storyboard 的 XCode 4 中以模态方式推送视图时发出警告

quot;Unbalanced calls to begin/end appearance transitionsquot; warning when push a view in a modal way in XCode 4 with Storyboard(“开始/结束外观转换的不平衡调用在带有 Storyboard 的 XCode 4 中以模态方式推送视图时发出警告)

问题描述

在网络上进行了一些研究但没有成功，我来这里问你关于我的警告的问题.

After some research on the web without success, I come here to ask you the question about my warning.

实际上，我有一个带有导航控制器的视图 V1，我想在 V1 完成加载后推送一个模态视图 V2.所以我使用 performSegueWithIdentifier 方法(我正在使用情节提要).这是我的代码:

Actually, I have a view V1 with a navigation controller and I want to push a modal view V2 when V1 has finished loading. So I use the performSegueWithIdentifier method (I'm using storyboard). Here is my code:

[self performSegueWithIdentifier:@"showConnexionViewSegue" sender:self];

当我编译时，我收到了这个警告:

And when I compile, I got this warning:

Unbalanced calls to begin/end appearance transitions for <UINavigationController: 0x6849b30>

谁能帮帮我?

推荐答案

听起来你可能在 -viewWillAppear: 中执行 segue 从而生成两个 -viewWillAppear:没有 2 条对应 -viewDidAppear 消息的消息.

It sounds like you may be performing the segue in -viewWillAppear: thus generating two -viewWillAppear: messages without 2 corresponding -viewDidAppear messages.

尝试在-viewDidAppear中执行segue.

Try performing the segue in -viewDidAppear.
