Ik heb hem ondertussen iets aangepast. Hij compiled succesvol maar zodra ik in de simulator op het plusje druk crashed hij keihard. Ik zie iets over het hoofd... Zal mn files posten:

Ik moet erbij zeggen dat ik nog niet alles snap en dat ik sommige stukken code uit andere sample projecten heb gebruikt, en aangepast naar mijn eigen code. Er kunnen dus misschien code instaan wat onnodig is of nergens op slaat. Hoop dat je me het dan kan uitleggen wat er niet klopt.
