remove UIImageView from subview

Question

I created UIImageViews and add it to subview. Then I add it to NSMutableArray.

So, I need delete from memory and subview object(UIImageView) in some index

[arr removeObjectAtIndex:index];

and

[arr replaceObjectAtIndex:index withObject:[NSNull null]];

don't help, because UIImageView doesn't disappear from View.

How to do this?

sorry for my English :)

Answer 1

I would not prefer to add them to array, just give items tag value

[imageview setTag:index++];

. And you can get views with

[self viewWithTag:index];

and remove them

[[self viewWithTag:index] removeFromSuperView];

Answer 2

[[arr objectAtIndex:index] removeFromSuperview];
