Question

I have a problem with my app where the code for which is far too long to go into, but suffice to say when i’m removing a UIView and replacing it with a new one like so:

NSLog(@" .. %@", (Icon *)[self viewWithTag:index]);
Icon *icon = (Icon *)[self viewWithTag:index];
CGRect frame = icon.frame;
int tag = icon.tag;
[icon removeFromSuperview];
[icon release];

Icon *icon2 = [[Icon alloc] init];
icon2.frame = frame;
[icon2 makeIconStandardWithTag:(int)tag];
[self addSubview:icon2];

It does some weird thing where that NSLog the first time (because the view is already there) shows that the object is an icon, but the second time after running this code shows that it’s a UIImageView for some reason now, and it displays what i presume to be the original icon at some odd position on the screen. It’s very erratic behaviour. But what i do know is this:

Removing the [icon removeFromSuperview]; line, although keeping the object there, stops this behaviour and causes the NSLog to return an Icon, as it should.

So my guess is that it’s not removing icon correctly. Is there a way to completely remove icon, or is removeFromSuperview as far as i can go. What i could do is just have it set to alpha = 0 but this is more of a patch-over solution and not how i want to solve it.

You can set the object to nil:

icon = nil;
