Convert ipad application to iphone. Universal app

 

Convert iPad application to iPhone- Universal app.

I already have one iPad application, now I want to make a universal app of that iPad application.

How to convert? Is it possible? Or do I have to start a new app?

Open up your project in Interface Builder. Click on the disclosure triangle next to "Targets", then right-click on the target and choose "Upgrade Current Target for iPad...".

Then read the iPad Programming Guide, especially the section Starting Your Project.

Edit:

I see now -- iPad to iPad/iPhone.

I think you would do something like the following:

  • Create a .xib for the iPhone for the Main Window/App Delegate/etc, to corresspond your existing .xib for iPad.
  • Add an entry in your info plist: NSMainNibFile , with the value of the name of your new iPhone xib
  • Go to your build settings and set the Base SDK to 4.1 (or 4.0 if you still have the older SDK installed)
  • Keep your iOS Deployment Target build setting at 3.2 if you're only worried about iPhones and iPod Touches with 4.x.
  • Set the Targeted Device Family build setting to iPhone/iPad
  • Start refactoring your code to create two different code paths, one for iPhone and one for iPad, where appropriate.
