Question

Whenever I call the code below,

BOOL currentState = [[allGroupThreeArray objectAtIndex:indexNumber] getState];

I get the the console errors below:

-[UIImageView objectAtIndex:]: unrecognized selector sent to instance 0x1f574d50

and

Terminating app due to uncaught exception ‘NSInvalidArgumentException’, reason: ‘-[UIImageView objectAtIndex:]: unrecognized selector sent to instance 0x1f574d50’

I have no idea why it says “UIImageView objectAtIndex” because allGroupThreeArray is an NSArray which is defined above the @implementation by the code below

static NSArray *selectedGroupThreeArray;

selectedGroupThreeArray is an array of instances of my class “ItemInstance” and “getState” is a public method in that class that returns a bool.

I have spent hours on this and have absolutely no idea what the issue is. Any help is greatly appreciated!

EDIT: indexNumber is defined by the code below

int indexNumber = itemNumber-300-1;

where itemNumber is a parameter that is sent to the method that all of this is occurring in.

Errors like this are usually signs of memory issues. Your array is probably released, but not set to nil before you try to call objectAtIndex:.
