The Three20 UITouch extensions break when using the iOS 6 SDK with the DEBUG flag set. This patch will cause the extensions to not be compiled by default in the Debug configuration; they must now be specified using the DEBUG_TOUCHES flag.
This patch comes wholly from @kemenaran in cogenta/three20-1.0.5@be70e1f.
UITouch extensions don't compile by default in Debug configuration
