Force iPad Pro to full resolution without Launch S

I want to use a Launch Image with my iOS app, not a Launch Screen. (Launch Images can target devices more precisely than Launch Screens; there's no way to make a launch screen that behaves exactly like a launch image.)

If you do not have a Launch Screen in your iOS app, the iPad Pro renders as if the screen resolution were 1024x768 points wide. (To see this, create a new project, delete its launch screen, and start it in iPod Pro simulator.)

Is there a way to get iPad Pro to render at native 1366x1024 points without using a Launch Screen?

回答1:

No, you must use a Launch Screen to support the iPad Pro. That is how Apple decided to support it.

If you can't find a way to use a single Launch Screen to get the results you want, you can provide one specific to iPhones and one specific to iPads.

Update: Xcode 8 supports an iPad Pro Launch image slot so you no longer must use a Launch screen file to support the iPad Pro.

回答2:

iPad 12.9 and iPad 10.5 can now be supported without using a Launch Screen.

I believe Xcode 8 briefly supported the iPad Pro within the xcassets file, but that support has been revoked.

However, a key has been added to the info.plist file that will allow for static images to be used.
