iphone - Xcode“此类不符合键 pageControl 的键值编码。”

Question

请有人帮助我！我整天都在这。我已经看到几个不同的stackoverflow问题得到了这个问题的回答，但我已经尝试了一切，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。

Answer 1

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).

Answer 2

您在 OneTranquille.xib 中的类定义是错误的。它显示“KMLViewerViewController”，但应该是“OneTranquille”

Answer 3

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。
