Using the STL in Objective-C

One of the really powerful libraries available to C++ programmers is the Standard Template Library (STL). While Cocoa has fantastic built-in classes, sometimes it is beneficial–especially when working with algorithms where raw numbers are being used and speed is more important–to use the STL.

Using the STL in Objective-C requires that you switch the file to use Objective-C++ by changing the file ending to .mm. After that you can import the various STL libraries normally: #import .
