XCode文档的API部分中的不同符号是什么意思？

Question

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!

Answer 1

• 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

Answer 2

I'm going to expand the list for XCode circa late 2011:

C: Class
M: Method
#: Define
f: Function
T: Typedef
K: Constants
G: Global instance
V: Keys for a dictionary and KVO/KVC
E: Enumeration
P: Property
(books,papers): Library
(a book): Category or conceptual document
(XCode icon): Sample code project
(sheet of paper): Document page or section
?: Help article
