NSRangeException from removeObjectsInRange: but passed range is within bounds

Question

I get the error below, which does not make sense.

* Application termination due to an uncaught exception 'NSRangeException', reason: '* - [NSMutableArray removeObjectsInRange:]: range {11, 15} goes beyond [0 .. 15]'

What am I doing wrong here? I'm within the array. Does deleting the last object in the array cause problems?

Answer 1

The second NSRange field is the length, not the endpoint. You are trying to delete fifteen objects starting at index 11.

Instead, you want to do something line by line:

 [myArray removeObjectsInRange:(NSRange){11, 5}];
