One UITableView - Multiple DataSource, best design pattern?

Question

This seems like a typical problem, but I have a UITableView that has identical behavior for two separate data sources. What is the best way of going about designing the class hi

Answer 1

Be careful with your terminology here. A UITableView has something called a dataSource but you seem to be referring, essentially, to two different sets of data.

In the case you're suggesting, in the table's dataSource (the object that adheres to the UITableViewDataSource protocol), I'd have three arrays.

• currentlyViewedArray
• datasetOneArray
• datasetTwoArray

In the dataSource methods, use the currentlyViewedArray as the source of the table's data.

Then, set the currentlyViewedArray to whichever array you want to view:

self.currentlyViewedArray = self.datasetOneArray;
[theTableView reloadData];

You can use the UISegmentedControl to switch between the two arrays.
