I can not find any data structure in Cocoa that maintains sorting
order of items gradually added in, using the pairwise comparison
results, something like the canonical set in C++'s STL that is
usually implemented as a balanced tree.
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:
