What do the different symbols in the API section of the XCode Documentation mean?

Question

Hi. Looking at the API section on the left side of the XCode Documentation, I've always wondered what the symbols mean?

For instance, there's a "K" in a green square, a "T" in an orange square, an "M" in a blue square, etc.

Is there a key for these?

Thanks!

• C: Class, like NSString
• M: Method, like -initWithString:
• #: Define, like nil
• f: Function, like CFStringAppend()
• T: Typedef, usually enums like NSStringEncoding
• K: Constants, usually a member of an enum like NSUTF8StringEncoding
• G: Global instances, usually strings like NSDirectoryFileType
