I am stuck with a minor problem (which according to our testers is an issue), that is, the image provided for LaunchScreen gets cropped in iPhone X,* models.
I have been trying to render the image itself on storyboard from Attributes Inspector but it is of no use. Since coding isn't allowed for LaunchScreen, I can't change the UIImageView properties programmatically.
I have set the contentMode for the UIImageView to scaleAspectFill. And hence it gets cropped.
Is there any way to fit the image corner to corner for each iPhone model on LaunchScreen?
iPhone 6 displays the image perfectly but it's not a good thing for the iPhone XR screenshot provided here.
Please help!

NOTE: This question is NOT related to launch image storyboards.
INFO: BG Buddy is a landscape only app. The launch screen uses images in a launchImage.xcassets file.
The launch image transitions to a UIViewController containing a full screen UIImageView with the same BG Buddy Background image as used in the launch image, and some textual UIButtons. This gives the impression that the buttons appear on top of the background image after a short time when the app has loaded.
Here is how the BG Buddy Background image set has been set up since the app’s release. Transitions from Launch Image to UIViewController work perfectly on iPad, iPhones 5,6,7,8 and 6,7,8 Plus.
The iPhone X and the iPhone Plus both seem to use the iPhone 3x image slot but both have very different dimensions. I’ve opened up the other size classes slots and tried to find a place with much confusion and no success. NOTE: All iPhones apart from the iPhone Plus use compact width/compact height size classes when in landscape. The iPhone Plus uses regular width/ compact height in landscape orientation.
So how do you set up 'image set' files to match launchImage files for all devices?
At the moment I can either have a good iPhone X transition or a good iPhone Plus transition but not both.
Is my only option to try to detect if it’s an iPhone X (or iPhone Plus) and swap the images programatically?
So here's the solution for a landscape only app. Hopefully it will help a little for portrait orientations too. Landscape bespoke launch images should be placed as shown with these width/height class settings.
Use the launchImage.xcassets screenshot at the top of the question to set up your launchImage.xcassets.
I designed an interface in sketch for an iOS app that I am creating and then exported the artboard as a pdf and placed it in Assets.xcassets in Xcode. I am now trying to make that image show up on the entire screen for all screen sizes. When I created the image in sketch, I used an iPhone 6 screen size (375 by 667). In Xcode now, the image takes up the whole screen on a iPhone 6 screen, but it doesn't take up the whole screen on any other device. It is too large for an iPhone 5 screen, so only part of the image is shown, and it is too small for an iPhone 6+ screen so there is white space on the screen. How do I make Xcode scale this image for all the different screen sizes? Thanks
1) First off make sure you're actually saving the asset as a vector:
It'll say Universal under and on the very right you'll notice it says Scale Factors: Single Vector
Now if You're still having issues it probably just means you haven't added constraints to the image. So it's just using the default size (the size you exported in).
If you're using storyboard or XIB make sure the image takes up the space it wants, click on it, then press on the little triangle on the bottom right of the storyboard and under Selected Views press on 'Reset to Suggested Constraints'
This should make sure the image resizes with different views. But because you might get different dimensions you'll probably want to set the UIIImageView's mode. Again on storyboard you can click on the imageView and then:
If you want the image to keep its aspect (not stretch in any direction) but want it to fill the entire space it has, put the mode on Aspect Fill
I'm trying to implement a "Launch Screen" .xib so that my app will get "This app is optimized for the iPhone6 and iPhone6 Plus" denotation in the app store.
So I create a new Launch Screen .xib template, delete the included label, drop a UIImageView onto it, I push the pin button and I set all the "spacing to the nearest neighbor" constraints to 0, I set the UIImageView to aspect fit, and have it point to one of my asset catalogs.
When I run the app on my phone, I'm getting some very weird results as far as the positioning of the UIImageView and the size of the image in it (it definitely isn't filling out the screen with the image). Does anyone have anyone have any idea of what I'm doing wrong here?
You don't give any actual details of what you are doing, so one has to guess. There are, however, two things to keep in mind here:
Where the image is shown doesn't really have all that much to do with the position/size of the image view. It has something to do with it, but the most important thing is actually the Content Mode of the image view.
Image views under auto layout are tricky, because they are resized based on the image - unless your constraints completely determine the height and width of the image view in some other way. In all probability your constraints are not doing that.
So the problem I was having was I trying to link the LaunchScreen.xib to a LaunchImage asset catalog. This will not work, you have to link it to a normal image asset catalog and use the universal image grouping.
Weird problem here which may be a bug in Xcode...
Using an Xcode 5.1.1 storyboard with auto layout, I am working on the design of a view controller that contains a full iPhone 4 sized UIImageView that references an xcassets image set. The xcassets image set includes 1x and 2x iPhone 3.5-inch images, and an iPhone 4 R4 image.
Problem 1: Once I set the Image View Image for the UIImageView in the utilities panel using a View Mode of Aspect Fit, the storyboard shows the smaller iPhone 3.5 image with white spaces at the top and the bottom of the view instead of the iPhone 4 image which would fill the entire storyboard representation of the view, as they are the same size since Xcode infers an iPhone 4 sized screen in the storyboard.
Problem 2: If I ignore problem 1 and run the program using the iPhone Retina (4-Inch) simulation, the applications selects the correct image size from xcassets and everything seems fine. However, if I run the simulation using the iPhone Retina (3.5-Inch) simulation, the applications also selects the correct sized image, but pushes the images down and display white space at the top of the page.
Before I start hacking around these problems, I thought I would reach out and see if anyone else has experienced either of these issues. Any help will be greatly appreciated.
This seems to be an interesting problem that I'm getting. I'm developing an iPhone app for iOS 6+ devices and optimizing the images for both iPhone 4 & 5. Now I have implemented this into my project: Xcode 4.5 background image iPhone 4, 4s, 5
The problem is in interface builder I'm designing the UI with the iPhone 5 screen, so the UIImageView is 320x568. But when I test on iPhone 4, the image is being stretched and looks terrible. However, the specified image for the iPhone 4 screen is displaying, i just want its dimensions to be 320x480
Hope someone can help!
From the inspector view in the interface builder, you can edit the stretching behavior of the view when the size of the super view changes. You can click the red arrows inside the square to control that.
Also I suggest that you check UIView contentMode. You can edit that from the inspector view in the interface builder "third tab from the right.
In the UIImageView's inspector, try playing with the Mode property. The Aspect Fill or Aspect Fit may get what you're looking for to handle the different screen sizes.
