Xcode "this class is not key value coding-compliant for the key pageControl."
提问by Jordan Clark
Please someone help me! I've been at this all day. I've seen several different stackoverflow questions that got answered with this problem, but I've tried everything, and I just can't figure it out. Here is my whole project so I don't have to paste multiple files worth of code here. The problem is that when I try to run my app, Xcode gives me this error in the console.
请有人帮助我！我一整天都在做这件事。我已经看到几个不同的计算器问题得到了这个问题的回答，但是我已经尝试了所有方法，但我就是想不通。这是我的整个项目，所以我不必在这里粘贴多个文件的代码。问题是当我尝试运行我的应用程序时，Xcode 在控制台中给了我这个错误。

Your Class definition in OneTranquille.xib is wrong. It shows "KMLViewerViewController" but it should be "OneTranquille"
您在 OneTranquille.xib 中的类定义是错误的。它显示“KMLViewerViewController”但它应该是“OneTranquille”

The error shows that the pageControl setter is being called on a UIApplication object but it is defined on your UIScrolView_... class. This indicates a mixup between two class names; one place where this is common is in nib files. It turns out that your 'Main nib file base name' (located in the Info settings for the KMLViewer target) is wrong - it should be MainWindow. Once you fix that - the application runs a bit further but runs into a 'map' setter problem (which is probably fixed by @obuseme's response).
该错误表明 pageControl setter 正在 UIApplication 对象上调用，但它是在您的 UIScrolView_... 类上定义的。这表示两个类名之间的混淆；一个常见的地方是在 nib 文件中。事实证明，您的“主要 nib 文件基本名称”（位于 KMLViewer 目标的信息设置中）是错误的 - 它应该是 MainWindow。一旦你解决了这个问题 - 应用程序运行得更远，但遇到了“地图”设置器问题（这可能已由@obuseme 的响应修复）。

A further error may be a wrong or unnecessary Outlet named pagecontrol. Take a look at the outlets in the connection inspector.
另一个错误可能是名为 pagecontrol 的错误或不必要的 Outlet。查看连接检查器中的插座。
