NSRangeException from removeObjectsInRange: but pa

问题:

I am getting the error below, which makes no sense.

* Terminating app due to uncaught exception 'NSRangeException', reason: '* -[NSMutableArray removeObjectsInRange:]: range {11, 15} extends beyond bounds [0 .. 15]'

What am I doing wrong here? I am within bounds of the array. Does removing the last object in the array cause issues?

回答1:

The second field of an NSRange is length, not endpoint. You are trying to remove fifteen objects, starting from index 11.

Instead, you want to do something along the lines of:

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