I'm trying to use Xcode's LaunchScreen storyboard as my launch screen? All the questions that have previously been asked about this refer back to the old launch image or .xib method - trying to do it now with the new LaunchScreen storyboard that Xcode automatically generates instead. I've selected the LaunchScreen storyboard as my launch screen file in my Deployment Info:
The storyboard itself confirms that it is set as the launch screen in it's file inspector.
And the info.plist file reflects this as well.
And yet, it doesn't work. The LaunchScreen storyboard never shows - it just goes straight to the first screen in my main storyboard. Using Xcode 7.2 and deploying to iOS 9.
回答1:
Enable these two settings for the LaunchScreen.storyboard

In case anyone else runs into this issue, I resolved it by simply deleting the ViewController on my LaunchScreen storyboard (leaving me with an empty storyboard), creating a new ViewController and resetting the Storyboard entry point to that new ViewController. There may be some sort of bug with XCode 7.2 with respect to the LaunchScreen storyboard and default entry point into the auto-created View Controller, but then again, I've tried replicating this 3 times and it hasn't ever repeated itself, so maybe not.

Just in case it helps someone. Scenario, I created my new project and copied a old Launch Image from another project. And then started getting the launch image but when I wanted to change it to new image then still i was viewing the old image it was stuck for ever as launch image no matter what I do. Then I reset my Simulator and restarted my iPhone and there you go I stared getting the new image. This looks like that somewhere in the documents or cache the devices store the old image until you reset the phone. Thanks

In my case I had all the suggested settings set correctly but continued to have the original blank launchscreen. In the spirit of AmJa's suggestion regarding a "cache" problem, I deleted my app from my device and reinstalled. Reinstalling did the trick for me on both my devices and simulators.

Another thing to make sure is that Launch Screen File is set to Launch Screen.storyboard
回答6:
If you are using xcode 11.2 you'll need to remove the app and execute it again to see the launch screen. I have to do this every time I modify the launch screen in order to see the new changes.

If you don't see anything and your Launchscreen.storyboard only has an ImageView in it, then it might actually be showing the storyboard but not the image. Try putting a button in it or something. I've discovered that my Launchscreen.storyboard is actually showing but won't show any images and I don't know why.

Other solutions didn't work for me, but this did:
- Toggle on and off Device Orientation (e.g. support Upside Down) and Hide Status Bar in General.
I'm not sure which one did the trick, but it's working now.
回答9:
In storyboard, in ViewController scene, I had to check Is Initial View Controller for storyboard to be seen as Launch Storyboard.
Suprisingly this is not checked when you add first View Controller. Xcode 11.
回答10:
As @abanet, mentioned in his answer, anyone who uses Xcode 11.2 and above, they have to delete their app and launch it again to see launch screen changes. It's not reflecting immediately. It looks like a bug from Xcode definitely not an intension.

I was banging my head against a wall with this since Xcode 10.1 does not include a launch option for the new 11" iPad Pro when you create a new iOS Launch Image set, and without it, the iPad Pro doesn't display correctly, leaving me no choice but to get this working with a Launch Screen storyboard.
I tried combinations of so many things, but I wanted to post what ended up making it work 100% of the time (which was, in fact, a combination of a number of things).
As you have no doubt read, for the UIImageView within the Launch Screen storyboard, you should NOT include the extension (.jpg or .png). So many posts say that, but leave out that the reason is that you should create a new image set within Images.xcassets (NOT Launch Screen image set, but just image set) and name it whatever you want (for instance, "Launch-Default"). Then, drag and drop the desired .jpg or .png into the new image set. You will then use the name of that image set within the UIImageView in the storyboard and everything should work fine (the image should even show up inside of Interface Builder).
Also, within the General settings for the project, make sure to set the Launch Screen File to your new storyboard.

In my case the background color of the view (full screen) was set to a "missing" color literal! After trying all above of course ;(
回答13:
in xcode9 swift4 LaunchScreen storyboard, use .jpg image & uncheck clear graphics context for imageview. it's absolutly working.
