XIB 文件无法在 Interface Builder 中正确加载
我正在 XCode 中创建一个新的基于视图的应用程序，使用 IBAction 和 IBOutlet 标记添加一些出口和操作到自动创建的控制器视图头文件中。然后，我双击“project_name_ViewController.xib”以启动界面生成器。 然而，出口和操作没有出现在界面生成器中。我能让它们出现的唯一方法是关闭 xib 文件并通过 file -> 重新打开它。在 Interface Builder 中打开命令是它自己的。
我最近升级到了Snow Leopard，在此之前我从未遇到过这个问题。
还有其他人遇到过这个吗？
I was creating a new View-based Application in XCode, adding some outlet and actions, using the IBAction and IBOutlet tags, into the automatically created controller view header file. I then double clicked the 'project_name_ViewController.xib' to launch the interface builder.
However the outlets and actions did not appear in interface builder. The only way I could get them to appear was the close the xib file and reopen it through file -> open command in Interface Builder it's self.
I recently upgraded to Snow Leopard, before that I never had this problem.
Has anyone else come across this?

Xcode 充满了奇怪的错误。在制作临时版本或发布版本之前，我总是遵循 15 步神秘黑魔法仪式。每当发生像你这样的问题时，我都会将其归咎于飞行猴子在 Xcode 中的某个位置扭转螺栓并重新启动程序（有时是计算机）。这通常可以修复它。
当然，对于出口和操作，很容易忘记在交换之前保存源标头。确保保存并构建。源中的错误也可能会阻止它们出现在 IB 中。
Xcode is full of strange bugs. I always follow my 15 step arcane black magic ritual before I make an ad-hoc or release build. Any time something like your problem happens, I put it down to the flying monkeys twisting bolts somewhere in Xcode and restart the program (sometimes the computer). That generally fixes it.
Of course with outlets and actions, it's easy to forget to save the source header before you swap over. Make sure to save and build. Errors in the source can stop them from showing up in IB too.
