I don't care the naming style, I care about the functionalities. And
it seems Cocoa is weak at supporting sorting-order-keeping data
structures at the high level APIs.
However, the reference is valuable. Thank you.

Unlike the C++ and Java standard libraries, which name data
structures based on their implementation, Cocoa's data structures
are named to describe their intended use - the internal
implementation isn't exposed, but you can rest assured that it'll
use something appropriate for the application. (Indeed, the internal
implementation may change based on the size of the collection.)
Anyways, since you're after an ordered list, what you want here is
NSMutableArray. Inserting elements into a sorted array comes up once
in a while; here's a recent discussion:
