iPad应用程序仅在更新到iOS4 SDK后显示黑屏 [英] iPad app only shows black screen after updating to iOS4 SDK

问题描述

我刚刚开了一个iPad应用程序，我一直在工作，它是工作正常，直到现在。我打开它，屏幕保持黑色，即使它的加载！它是一个OpenGL，我只是下载了iOS4 SDK。我还添加了一个配置文件。这些更改会导致一个完全黑屏，没有任何错误，根本没有什么？

I just opened an iPad app I'd been working on and it was working fine, until now. I open it and the screen remains black, even after it's loaded! It's an OpenGL and I just downloaded the iOS4 SDK. I also added a provisioning profile. Would any of these changes result in a completely black screen with no error for no reason at all?

它加载MainWindow.xib但不显示它。它的想法，但不注册触摸事件。

It loads the MainWindow.xib but doesn't show it. It's thinking but doesn't register touch events. All this was working until now.

解决方案：
使用界面生成器打开MainWindow.xib
选择窗口属性中的窗口
检查启动时是否可见和启动时是否全屏。

Solution: open your MainWindow.xib with Interface Builder select the window in Window Attributes check Visible at Launch and Full Screen at Launch.
