NSMutablearray move object from index to index

Question

I have a UItableview with reordable rows and the data is in an NSarray. So how do I move an object in the NSMutablearray when the appropriate tableview delegate is called?

Answer 1

You can't. NSArray is immutable. You can copy that array into an NSMutableArray (or use that in the first place). The mutable version has methods to move and exchange its items.
