i want to remove currencyViews (tableViews) that are not more needed. i can change dynamically them, and if i had 6 currencyViews and now are 4 , those 2 (not showed) still exist. how can i remove them ?
- (void)loadScrollViewWithPage:(int)page {
if (page < 0) return;
if (page >= numberOfCurrencyViews) return;
// replace the placeholder if necessary
CurrencyViewController *controller = [self.currencyControllers objectAtIndex:page];
if ((NSNull *)controller == [NSNull null]) {
controller = [[CurrencyViewController alloc] initWithPageNumber:page];
controller.delegate = self;
[self.currencyControllers replaceObjectAtIndex:page withObject:controller];
[controller release];
}
// add the controller's view to the scroll view
if (nil == controller.view.superview)
{
CGRect frame = scrollView.frame;
frame.origin.x = frame.size.width * page;
frame.origin.y = 0;
controller.view.frame = frame;
[scrollView addSubview:controller.view];
}
}
