I'm trying to complie my app for iOS 4. It includes Three20. I've set the base SDK to "iPhone Device 4.0" and the Deployment Target to "iPhone OS 3.0" but I get this message:
"_OBJC_CLASS_$_TTURLRequestModel", referenced from:
_OBJC_CLASS_$_MockPhotoSource in MockPhotoSource.o
What do I have to do?
