I'm creating a tableview from a plist which contains an array of 6 dictionaries.
One of the fields in the dictionaries is LastUpdatedDate, which I'd like to use as the table section value.

I'm trying to populate the section array using the code below, but nothing is added.
Any ideas?

```
BOOL found;
for (NSDictionary *document in documents){

    NSString *date = [document objectForKey:@"LastUpdatedDate"];

    found = NO;

    for (NSString *str in sections){

        if ([sections containsObject:str])
        {
            found = YES;
        }
    }

    if (!found)
    {

        [sections addObject:date];
    }

```
