Currently, Homepwner can be run on the iPad simulator, but it will not look right.

This is not what you want for your iPad users. You want Homepwner to run natively on the iPad so that it will look like an iPad app. A single application that runs natively on both the iPad and the iPhone is called a universal application.

Reopen your Homepwner project. In the project navigator, select the Homepwner project (the item at the top of the file list). Then select the Homepwner target in the project and targets list and the General tab. This tab presents a convenient interface for editing some of the target’s properties.

Locate the Deployment Info section and change the Devices pop-up from iPhone to Universal (Figure 15.2).

Homepwner is now a universal application. To see the difference, select an iPad simulator from the scheme pop-up menu and then build and run the application. Homepwner looks much better. The table view and its rows are sized appropriately for the iPad screen.

Now add a new item to get to the detail interface. Here the results are not so good:

The table view interface knew how to resize itself for the iPad sized-screen, but your custom detail interface needs some guidance. You will provide that guidance using Auto Layout.
