stored in the array is a pointer, a pointer is alloc these imageview out when alloc when the counter is a pointer, added to the array when the counter is incremented by one into two, you are not adding after release once, this time, the counter becomes one, you are here and use the image = [array objectAtIndex: i];
[Image release];
So this time the pointer counter to 0, calling array removeAllObjects]; put all the pointers array counter by one, it will collapse.
Anyway, you look, you generate these pointers when, after joining the array is not the calling code release?
