GroupFriendsController.m @ 843

Revision 843, 18.2 kB (checked in by henri, 2 years ago)
Upgrade to XCode 4.0: fixes to warnings, recompile of ldns framework to us A6 and A7 processors, and added custom header search paths to make it work with XCode 4. Bug fix for keywords > 255 characters, and now properly dynamically resizes keyword cells. Changed app icon. Added French localization.
