What does "Main Interface" in Xcode actually *do*?
提问by Christophe
I'm moving some older projects to Xcode 4.5, and I'm a bit baffled as to the actual function of the Main Interface project dropdown. What does the framework actually do with that value?
我正在将一些较旧的项目移至 Xcode 4.5，我对 Main Interface 项目下拉列表的实际功能感到有些困惑。该框架实际上如何处理该值？

That's where you can specify what Interface Builder file (xib) you want to load on launch, if you're not using a Storyboard.
如果您不使用 Storyboard，您可以在此处指定要在启动时加载的 Interface Builder 文件 (xib)。

beware if you have a storyboard based project. Editing the MAIN INTERFACE field manually is dangerous. If storyboard is not found it thinks you mean a NIB. will change the app to a NIB based project. Safer to choose a storyboard from the drop down.
如果您有基于故事板的项目，请当心。手动编辑 MAIN INTERFACE 字段是危险的。如果未找到故事板，则认为您的意思是 NIB。将应用程序更改为基于 NIB 的项目。从下拉菜单中选择故事板更安全。
BEFORE - i has a storyboard based project
UIMainStoryboardFile~ipad : Main_iPad
UIMainStoryboardFile : Main_iPhone
I mistype the name in MAIN INTERFACE field to Main_iPhone1 I ran the app and it crashed as Main_iPhone1.storyboard doesnt exist I changed it back to Main_iPhone but project refused to build even after a lot of cleaning.
我将 MAIN INTERFACE 字段中的名称错误地输入到 Main_iPhone1 我运行了该应用程序，它崩溃了，因为 Main_iPhone1.storyboard 不存在我将它改回 Main_iPhone 但即使经过大量清理，项目也拒绝构建。
Casued by the key in the plist also changing along with the value
由 plist 中的键引起的也随着值而变化
AFTER
UIMainStoryboardFile : Main_iPad
NSMainNibFile : Main_iPhone1 <<project changes to NIB based
Changing Main_iPhone1 back to Main_iPhone only changed it from Main_iPhone1.xib to Main_iPhone.xib which doesnt exist and also crashes.
将 Main_iPhone1 改回 Main_iPhone 只会将其从 Main_iPhone1.xib 更改为 Main_iPhone.xib，它不存在并且也会崩溃。
