First, I will use static image for splash screen.
I have a quick questions about registering launch image.
I was trying to add images in launchImage file in Images.xcassets folder. However, I don't let user to rotate screen so I don't need landscape images. Do I have to add all of images in launchImage file to complete launch images?
Thanks.
Apple recommends to use a Launch Screen that let you to have the page automatically adapted to the screen sizes of different devices and environments

I am trying to use a LaunchScreen.storyboard to show a simple image.
I followed the instructions here
The image that I am trying to use doesn't show up.
I have another image in my assets.xcassets file that when I set the exact same ImageView to that one it shows up fine.
If I copy the image I want over the top of the image that works in its own folder under Assets.xcassets folder then the image I want works.
I just can't get the image I want located in its own Assets.xcassets folder to work as a splash screen.
If I add an to any of my xaml forms then the image shows up fine.
The image also shows up fine in the storyboard editor in VS2019.
I am totally confused about why this image doesn't work as a splash on a LaunchScreen.storyboard.
I am hoping someone can help me figure it out.
This is a screenshot of my storyboard:
When I run the app I don't get anything other than a black splash screen.
Here is a screen shot of the exact same storyboard where I have changed the Image setting to another image in my Assets.xcassets.
When I have it set to that one the splash shows that image just fine on startup.
Here is an image of my Assets.xcassets folders:
As I said before if I simply copy and paste the image that doesn't work over the top of the one that does inside the Assets.xcassets folder (renaming it of course), then the image I want works fine as the splash.
So it is not the image itself. I don't understand what is going on.
I'm running into an issue where an iOS app project using Launch Storyboard does not display some images from the asset catalog. But it can display another image in the same image view. This tells me that the image view is set up correctly, and something is wrong with the image itself
How can I understand why my image is not displayed on launch screen when starting app?
I checked the asset catalog membership, and the images are members of the correct target. The image displays in the interface builder preview.
I checked and images are not displayed when saved in either JPG or PNG format.
The image previews fine on Storyboard preview.
I tried using smaller image, so it doesn't seem to be a file size issue.
Does not work on either device or simulator.
This image displays:

I am trying to show multiple images in splash screen. Now I am showing only one image. How can I show multiple images in Xamarin Forms.ios project. Please suggest any idea. Thanks in advance.
Look into creating a launch screen using the Interface Builder. You can put images, labels, basically every control on there if you want and set it as the launch screen in your info.plist. When creating a new project you will get a launch screen storyboard file in your iOS project.

I want to show multiple images one after another in splash screen, So I decided to set multiple images are converted in to gif image and add this gif image as a launch image. Can we set gif as launch image. Please suggest any idea to beat this requirement. Thanks in advance.
According to Apple's guidelines it's not possible to use a GIF as/in a splash screen. Like I said in your other question, you can fake an animation by making your first view controller animated and setting it as the splash screen.
The UIImageView control in iOS has the ability to play a sequence of images one by one.
Is landscape splash screen supported in iPhone? I don't see the option like I do with iPad, as such:
That's Visual Studio?
Because I am able to see the iPhone Landscape option in Xamarin Studio.
Try switching on and off the "Assets Catalog" dropdown to see if that helps.
Also if that doesn't work you could change at anytime from Launch image to Launch screen and there you can configure your Storyboard for all different sizes and orientations.
Note: will check later in VS.
You could add them to your assets. I don't think image assets are rendered properly in VS. It doesn't show specialized image for iPhone, iPad, watch etc. Only the generic one.
Another thing you might want to consider is using launch story board and not launch images. That's the new way of doing it or the suggested way by Apple. You have far more control on it.
Customizing launch images - Manual approach
Open LaunchImage.launchimage and change the default launch images with your own using the proper resolution for each image (e.g., Default-568h#2x.png should be 640px x 1136px). If your images have different file names then open Contents.json and change the key filename for each image.
Xcode WYSIWYG approach
Drag and drop your Assets.xcassets into Xcode (7.1 or newer version). In the opened window choose LaunchImage and add the proper image for each iOS version and device. Close Xcode and rebuild your Xamarin app to use the new launch images.
