If your app runs only in landscape orientation, you should always launch in landscape and let users rotate th

If the device is already in landscape, a landscape-only app should launch in that variant, unless theres a very good reason not to. Other
16、wise, launch a landscape-only app in the variant with the Home button on the right.Supply a launch image that closely resembles the first screen of the app. iOS displays the launch image the moment your app startsgiving users the impression that your app is fast and giving your app enough time to load content. Learn how to create a launch image in “Launch Images” (page 186).If possible, avoid requiring users to read a disclaimer or agree to an end-u
