Two PickerViews in save View issue?
- by NextRev
I'm trying to have 2 pickerviews in the same view. It works except for two things. If one pickerview has more rows than the other the app crashes when picking an item from the pickerview with more items. Also I created an NSLog for the pickerviews and the console shows that I'm picking two items at once when in fact i'm only dealing with one pickerview. I know it sounds a bit confusing but I'm including all the code. Thank you in advance.
list and list2 are NSMutableArrays
list has 4 items
list2 has 5 items
There error:
* Terminating app due to uncaught exception 'NSRangeException', reason: '* -[NSCFArray objectAtIndex:]: index (4) beyond bounds (4)'
