Less than 200 lines of code, only a couple of which aren't basically boilerplate stuff specific to ObjC/Cocoa/iOS. So who cares what the license is? Just rewrite it. I assure you:

x = (p1.x + p2.x) * 0.5; y = (p1.y + p2.y) * 0.5;

is not now only allowed in GPLv3 code just because it appeared in this larger body of code which is GPLv3.

Rewriting is also nice because you will actually make it better and more fit to your own project
