This is probably an simple problem but would someone nice be able to give me a hint what is wrong in the following scenario, i just do not understand. I have a NSMutableArray "playerArray", which have objects "ZERO", "ONE", "TWO", THREE".

I am trying to remove the object at "row" but it does not work. Could it be so that it returns a immutable array as the exception seems to getting thrown because it doesn't respond to removeObjectAtIndex?

 NSUInteger row = 1; // [indexPath row];
 NSLog(@"playerArray:%@", playerArray);
 NSLog(@"row: %i", row);
 [playerArray removeObjectAtIndex:row];

The result is:

playerArray:(
ZERO,
ONE,
TWO,
THREE
)
