using completion with animateWithDuration causes exc_bad_access

Question

I am trying to animate 2 UIButtons in a UITableViewCell called addToPlaylist and removeFromPlayList (they animate off to the right after being swiped on) and am using a bloc

Answer 1

I had the same problem with animations. I've solved it by removing -weak_library /usr/lib/libSystem.B.dylib from Other Linker flags.

Also, according to this answer, if you need this flag, you may replace it with -weak-lSystem.
