从模态视图呈现视图 - 控制给错误

Question

调试试图从一个模式的看法要到普通视图 - 控制（PBSViewControllerDataDetail.h）时，我的应用程序时，我得到一个断言失败错误（不是原来的观点，即呈现控制器模式的看法）

本质上讲，我试图做的是：

ViewController1，开放模式的看法，做一个异步请求。当它返回时，将用户发送到第二个普通视图控制器，该视图控制器将向用户呈现在模态视图内获得的数据。

其他一切正常工作，直到模态显示第二个视图控制器。我得到的错误（1号线是从改掉呈现第二VC的方法中我的NSLog输出）

2013-09-22 07:24:11.411 PBSDashboard[566:1303] *** Assertion failure in -[UIWindowController transition:fromViewController:toViewController:target:didEndSelector:], /SourceCache/UIKit_Sim/UIKit-2380.17/UIWindowController.m:211 

请注意：我不这个项目中使用NavigationViewController，并考虑重新启动整个很多，但使用一个，但此刻我只是想了解如何从Modal转到正常的ViewController，而不是原来的。

我已经尝试清理目标，重新创建第二个VC从头开始，都没有成功。

从模式到 '正常' 的，你应该呈现“正常'模式控制器后面的控制器（通常位于根控制器中）然后解散模态。有一个导航控制器作为窗口的根视图控制器可以让生活更轻松，因为它可以是模式的主机。在任何时候你都不应该试图使用从模态到“正常”的过渡，而是始终忽视模态。模式是在屏幕层的概念上不同的水平，如果这是有道理的...
