I\'ve gone through a bunch of answers regarding this problem but none seem to relate to my problem.
I have two views, View 1 has a button. View 2 has a button.
I faced this when I extracted a .app from a zip file and attempted to run it, both on an iOS device and on Simulator.
One .nib file had been named with non-latin characters (fileNormal.nib with the greek letters No) and when extracted from the zip, it was assigned letters from another charset (it should be Greek-DOS or something compatible). I chose a different charset upon extraction and it worked as it should.
Just putting this in case someone else faces the same problem ;)
