Problem renaming xcode classes

i'm trying to rename my classes in iOS project in xcode but i cant.

If i try to rename the file in navigator, or if i make refactor 开发者_开发知识库-> rename on class name in .h file, it replace all except .h and .m file, it say me:

"Unable to rename oldName to newName, oldName couldn't be moved to appName"

How can i solve this?

Thanks.

Type in the name of your project in the finder, and locate the class files and header files inside that. Try renaming it through that
