Question

我有一个在IB 3.x中创建的XIB解决方案。当我在xCode 4中编辑它们并保存更改时，我的Xib文件都搞砸了并且没有显示任何内容 - 只是空白屏幕。

也许项目没有正确升级？如果有人有任何想法，请尽快告诉我 - 我无法编辑任何XIB！

设定：我仔细检查了MT和MD是最新的。 2.编译ios 4.x. 3.根据我的设置和解决方案，问题是100％可重现的

以下是文件的前后文件。以下是我用来解决问题的确切步骤。

由于5K限制，我无法发布整个文件但是jist是新的Xcode 4文件有完整的getter和setter。

以下是我用来重现它的步骤：

运行该应用并验证相关视图是否正确显示
双击nib文件以在xCode 4中打开它
将圆形rect按钮拖放到View
选择保存“xxxx”
在Debug | iPhoneSimulator中运行应用程序。它正在显示视图。
停止应用
双击同胞以在xCode 4中打开它。
控制 - 从按钮拖动到.h
创建名为cmdDosomething
关闭并保存文件。
在视图的ViewDidLoad和ViewDidAppear的开头设置断点。
重新启动应用程序
单击显示视图的选项卡。 ViewDidAppear被点击了。 ViewDidLoad没有被点击。视图会显示 NOT ，标签栏上方只有一个空白区域
在标签上随机点击。所有其他观点看起来很好。 ViewDidAppear在相关视图上正常调用。

我真的很感激指点或想法。太感谢了 WCM

Answer 1

我有同样的问题，并且能够找出原因和解决方案：

我在2.8之前创建的视图有一个名为view的视图的插座。当我打开头文件时，我发现XCode抱怨视图的声明是重复的名称。

由于这似乎可能是问题的根源，我采取了以下步骤：

1）删除文件所有者的出口列表中的视图出口

2）手动删除头文件中对视图的两个引用

3）将文件所有者的出口列表中的View插座直接链接到视图（我没有将连接拖到头文件中，我将其拖动到设计器区域左侧的视图中）。如果您忘记执行此步骤，则会收到有关正在加载的nib但未发送视图插座的运行时错误。

希望这有助于您解决问题。

我忘了提到：设计师档案是正确的; MT改变了在设计器文件中识别出口的方式。

Monotouch - 转换为xCode 4 - XIB无法正常工作
