cocoa - Is there a Stack class in Objective C that I can import and use? -

i need stack adt in application. avoid making wrapper on nsmutablearray; there must efficient implementation in foundation somewhere.

so, how access it?

you've got couple of options; if want stack, use std::stack stl. sure include #import <stack> rename .m files use .mm.

the other option write objective-c class either wraps std::stack, or provides stack interface nsmutablearray. include despite wishes contrary, because unless have profiled code uses nsmutablearray, have absolutely no business complaining performance.
