Hello -
I am a bit confused on when or why a view is cached and what is the
best possible way to clear it.
First:
I have a UITabBarController. The views that this brings up are cached.
This is actually great as I can test to see if something is changed
and if so, do nothing and it brings up my view quick. So far so good.
However, when I issue a viewWillAppear it seems that instead of "re-
creating" my view it is actually overlaying my new image views on it
without the old ones going away. I have done something like:
NSEnumerator *itemEnum = [ [veggieScrollView subviews]
objectEnumerator];
UIView *tView;
while (tView = [itemEnum nextObject]) {
if([tView tag]==101)[tView removeFromSuperview];
}
And it clears those images but that seems rather poor to me and that
their must be a better and cleaner way.
Now I also have views that I popup from those parent views above and
they DON'T cache the view so they have to be reconstituted in their
viewWillAppear each time. This is bad because those popups have
content that never changes once the program loads.
So in their case, I want them to be cached.
Any help would be greatly appreciated.
