Answer 1

Use NSMutableArray. It has methods like

- (void)replaceObjectAtIndex:(NSUInteger)index withObject:(id)anObject;


- (void)exchangeObjectAtIndex:(NSUInteger)idx1 withObjectAtIndex:(NSUInteger)idx2;

It does not matter whether your objects are strings or images or whatever. It is possible to change the objects in a mutable array.
