Getting Started with iOS development: building an Adaptive iphone and ipad project

Sometimes applications need to be able to run on the iphone and ipad, and of course we can choose to do two completely different projects and then share some of the classes, but we can just create a project and build a product that can be adapted to the iphone and ipad devices, and then the app When Stroe is released, it will have two sets of different screenshots to show to the user. App Store's Evernote app, which has two screenshots of the iphone and ipad, shows that Evernote is the adaptive iphone and ipad device.

Let's do a project called Universalsample for adaptive iphone and ipad devices.

First of all, select Devices as "universal" at the time of creation, we have always chosen the iphone, if the development of ipad-specific applications need to check the ipad.
