xcode - Convert simple iPhone app to Universal app

Question

I have very simple iPhone app, which uses just UIButtons, UIlabels, UITableView. without any custom controllers and graphics. How can I convert app to universal with that UI?

Answer 1

First update the application target device to Universal.

1. Update the application target device to Universal.
2. Check the Info.plist for NSMainNibFile & NSMainNibFile~ipad keys.
3. For all other views, have two different NIB. For example FirstView.xib & FirstView~ipad.xib. iOS runtime will load the proper view based on the device.

Here is a screenshot of a sample project:
