Parse iOS SDK Depends on Facebook SDK if you use -ObjC linker flag when building your project, which you probably do.
The new Parse iOS SDK has a quiet dependency on the Facebook SDK.
If you link all categories implementations from libraries in an iOS app using the -ObjC
linker flag, the Parse library will whine that you don't have some Facebook SDK categories
2 ways around this:
bring in the Facebook SDK, yuck.
stop using the -ObjC linker flag and use the
-force_loadlinker flag once for each static library / framework that your project links
"Fun" facts that I learned while doing this:
-force_loadgoes on a single line in other linker flags the following line is it's target, your library
if you include third party libraries via a dependent project,
-force_loadhas to point at the correct build configuration, a typical one for me looked like this:
-force_loadat the mach-o binary in a static framework … works
