我发现 http://mithin.in/2009/06/22/using-iphone-sdk-mapkit- framework-a-tutorial / 但是，就像我说的，我已经添加了框架。我错过了什么？

I found http://mithin.in/2009/06/22/using-iphone-sdk-mapkit-framework-a-tutorial/ but, like I said, I've already added framework. What am I missing?

推荐答案

我也碰到了这个，但是我按照步骤的说明我能够通过它链接中的2（顺便说一句，谢谢）：

I ran into this too, but I was able to get past it by following the instructions of step 2 in your link (thanks, by the way):

1. 添加MapKit框架到项目。 （控制+单击框架
   文件夹 - >添加 - >现有框架）

I刚搜索了MapKit.framework，将其添加到项目中，错误就消失了。

I just searched for MapKit.framework, added it to the project, and the error went away.

我还没有添加任何地图代码（虽然我有一个MapViewDelegate在IB）连接，但它到目前为止工作正常！

I haven't added any map code yet (although I do have a MapViewDelegate connected in IB), but it's working fine so far!
