You’ll want to use “sections” to split the table.<\/p>\n

First you need to sort your datasource into the desired groups, and then reflect it in the view.<\/p>\n

A dictionary can easily represent the grouped data. Model each group as an array that contains the entries for that group, and then add it to the dictionary with a key that represents the section.<\/p>\n

When the data is ungrouped, you can still use the dictionary, but with a single entry, rather than many, and then reflect that in the UI.<\/p>\n

That way when you’re asked how many sections there are in the table you can return [dictionary count];<\/code> and then when you’re asked for the number of rows, you can do something like [[dictionary objectForKey@\"myKey\"] count];<\/code><\/p>\n

And so on.<\/p>\n

When you’ve reconfigured your datasource you can call [self.tableView reloadData];<\/code> to reload the table with the sections.<\/p>\n","protected":false},"excerpt":{"rendered":"
