Assuming the sub elements within each key are NSArrays, then you can just return the number of keys in the dictionary as the number of sections, the actual key for the title for each section, and then for the number of rows in each section return the number of elements in the array under that particular key

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    return [myDictionary count];//returns the number of key/object pairs
}

- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section
{
    NSArray *allKeys = [myDictionary allKeys];
    return [allKeys objectAtIndex:section];
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    NSArray *allKeys = [myDictionary allKeys];
    NSString *curKey = [allKeys objectAtIndex:section];
    NSArray *curArray = [myDictionary objectForKey:curKey];

    return [curArray count];
}


- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    //normal cell acquisition code

    NSArray *allKeys = [myDictionary allKeys];
    NSString *curKey = [allKeys objectAtIndex:indexPath.section];
    NSArray *curArray = [myDictionary objectForKey:curKey];
    NSString *curValue = [curArray objectAtIndex:indexPath.row];
    //Do something with the string
}
