I think I’ve got a similar app: A list of item., tap ‘+’ -> new screen, come back and see the updated list, scrolled to show the added item at the bottom.
In summary, I put reloadData
in viewWillAppear:animated:
and scrollToRowAtIndexPath:...
in viewDidAppear:animated:
.
// Note: Member variables dataHasChanged and scrollToLast have been
// set to YES somewhere else, e.g. when tapping 'Save' in the new-item view.
- (void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
if (dataHasChanged) {
self.dataHasChanged = NO;
[[self tableView] reloadData];
} else {
self.scrollToLast = NO; // No reload -> no need to scroll!
}
}
- (void)viewDidAppear:(BOOL)animated {
[super viewDidAppear:animated];
if (scrollToLast) {
NSIndexPath *scrollIndexPath = [NSIndexPath indexPathForRow:([dataController count] - 1) inSection:0];
[[self tableView] scrollToRowAtIndexPath:scrollIndexPath atScrollPosition:UITableViewScrollPositionBottom animated:YES];
}
}
I hope this helps. If you add something in the middle of the list, you could easily scroll to that position instead.
