NSMutableArray addObject: -[__NSArrayI addObject:]: unrecognized selector sent to instance

Question

I have tried to initialize my NSMutableArray 100 ways from Sunday, and NOTHING is working for me. I tried setting it equal to a newly allocated and initialized NSMutableArra

Answer 1

The synthesized setter for @property (copy) sends a copy message to the array, which results in an immutable copy.

You have no choice but the implement the setter yourself here, as detailed in the Objective-C guide.
