Seeing black bars at the top and bottom of the iPh

问题:

Running my App in the iPhone X Simulator (GM Seed) I am noticing two strange effects:

• the App does not use the full screen space (top and bottom area is black)
• a strange white bar beneath the title bar

Does anybody know what is happening here and how to resolve this? I can\'t find any new settings in Interface Builder.

回答1:

When using launch images (instead of the much easier Launch screen file), you need to provide the properly sized launch image for each device size you wish to support. Once you add the additional launch image, your app should take advantage of the new screen size.

The new iPhone X requires a launch image sized at 1125px × 2436px which is a 3x image for 375pt × 812pt.

Of course if you switch over to using a Launch screen file instead of individual launch images, your app will automatically adapt to all device sizes without any additional work.

iPhone X needs different launch image sized 1125px x 2436px (375pt x 812pt @3x).

Check human interface guidelines for more details.

I have figured out how to fix (though I still don\'t understand why this happened only on iPhone X) LaunchScreen storyboard on iPhone X with seeing black top&bottom bars.

I have LaunchScreen storyboard with one UIImageView.

UIImageView\'s top&bottom has to be pinned to SuperView\'s top&bottom. NOT to SafeArea.

I fixed it by simply inserting some random text in the Lanch Screen File textfield. I dont even have a Launch Screen File... XCode is so buggy.

update

Although this fixes it in simulator (still very weird and unexpected) when uploading a binary to iTunes Connect it will fail due to not finding a LanchScreen file of name \"random-name\"

If you already have a 1125px × 2436px launch image but the app is still not using the full screen check to make sure that your image is PNG.

回答7:

if you removed LaunchScreen.storyboard; Choose your project, select your project target, General -> App Icons and Launch Images -> Launch Screen File: Select here Main.storyboard instead of LaunchScreen.storyboard

回答8:

Just ran into this while trying to update an app I hadn\'t worked on in a while.

On Xcode 9.4, I was able to fix this by doing the following:

1. Add a launch screen by going to File -> New -> File... -> Launch Screen

1. Make sure the newly added launch screen storyboard is selected as the launch screen file under project settings.
