UITableView section index related crashes under iOS 7

Question

I have a simple section index for a table view that appears fine for the first time but then crashes if certain kinds of interaction happens that force a redraw of the section i

Answer 1

I discovered that the issue is in the function:

- (NSArray *)sectionIndexTitlesForTableView:(UITableView *)tableView

There is something wrong with the section indexes algorithm after iOS 7.0, and Obviously it's a framework bug. I ended doing something like this:

- (NSArray *)sectionIndexTitlesForTableView:(UITableView *)tableView  {
        **if(IS_IOS7 || isSearching)
            return nil;**
        else
            return [self.dictAllKeysAlphabetically allKeys]; 
}

This is an ugly patch which will remove the letters bar from right side of your screen, but at least your app won't crash.
