Question

my app crashes on iPad when I open a new view even though in the simulator it works like a charm.

Any help is strongly appreciated!

Thanks in advance

Answer 1

I deleted the App on the iPad and run it again.

It looks like that an array generated from a text file which i am reading out with componentsSeparatedByString: had less entries than i was accessing.
