Application Architecture

[Cardinal]

I'm new to iPhone development. (Been doing .NET development for 8 years)

I'm building an app, and am having trouble with the architecture of the application.

My first screen has 8 buttons on it, that each go to different views. Some of these views are table views with data from a Core Data entity.

Do I need to setup a view controller for each of these different table views? I think that i do, but not sure. Also, does each different view controller also needs its own delegate class?

If anybody knows of a sample app that has this type of functionality, that would be helpful too.

Thank you very much.

The most likely design will be one controller class for each view.

Only those things that need delegates need delegates, and your basic UIViewController subclass doesn't. You can think of a delegate as a designated target class for named callbacks.

For instance: UITableView has a number of delegate methods it calls to get its data and to report user interaction, and it's customary to have the UIViewController that controls that view be the table's delegate. SO customary, in fact, that there's a UIViewController subclass called UITableViewController that combines those two things for you.

Hi,

I think it really depends on how common the data and presentation will be for those tableViews. If they are very similar, then I would use the same viewController and just modify the properties of the viewController and load the appropriate tableViewCells based upon the dataset that you are loading.

This is not trivial to do, but it is possible. With a little bit of work up front architecting it, you can make a fairly reusable class that can be adapted to the situation at hand.

Good luck,
