AppViewController和Delegate扩展名更改为.mm，#import“OpenFeint.h”给出 OpenFeint 需要 Obj-C++ 的错误

我下载了 OpenFeint 版本 2.3.1，解压缩并将 OpenFeint 文件夹放在 Xcode 中我的项目正下方，并选中“如果需要，递归创建组”（说明中说使用组而不是文件夹引用）。我将 AppViewController 和 AppDelegate .m 文件重命名为 .mm。我按照其余的说明进行了编译并运行，该应用程序运行良好。在 AppViewController.mm 中，我执行：

#import "OpeinFeint.h"

并编译，这给了我错误：

#error: "OpenFeint requires Objective-C++. In Xcode, you can enable this by changing your file's extension to .mm".
#error: syntax error before 'OfNotificationCategory'
#error: syntax error before 'OfNotificationCategory'

并且错误的位置将我带到 OpenFeint 文件。我确实将 -ObjC 添加到“其他链接器标志”并选中“在 Objective-C 中调用 C++ 默认 Ctors/Dtors”。有什么建议吗？谢谢！

I downloaded OpenFeint version 2.3.1, unzipped and placed the OpenFeint folder inside right underneath my project in Xcode, and checked "recursively create groups if needed" (the instructions said to use groups and not a folder reference).
I renamed my AppViewController and AppDelegate .m files to .mm. I followed the rest of the instructions and compiled and ran, the app works fine.
Inside AppViewController.mm I do:

#import "OpeinFeint.h"

and compile, which gives me the errors:

#error: "OpenFeint requires Objective-C++. In Xcode, you can enable this by changing your file's extension to .mm".
#error: syntax error before 'OfNotificationCategory'
#error: syntax error before 'OfNotificationCategory'

and the location of the errors takes me to the OpenFeint files.
I did add -ObjC to Other Linker Flags and check Call C++ Default Ctors/Dtors in Objective-C.
Any advice? Thanks!
