I've been building a cross platform PCL. Forms app and recently got to focusing on the IOS portion.
Launch Screens for Xamarin.iOS Apps
I've been trying to create a LaunchScreen that is white with a decal in the center. However when launched despite being in the center of the editor, the image is nowhere near centered on the actual splash screen.
As if the phone is trying to display what is shown on the editor as in image based in one of it's corners rather than the center.
How can I get the phone to display the center of the storyboard rather than a corner? What you want to do is use a constraint that will centre the view. Auto generated constraints won't do this for you as what they do is just place constraints to fix everything in place as it is in the editor - this just satisfies iOS at runtime Xcode has the same behaviour.
In the designer you can grab the dot in the centre of the view and then drag it to the vertical or horizontal lines:. What I found that worked for me was to set content mode to "Center" and then set the image UI control to fill the entire storyboard screen so that the UI control fills the screen and the image is centered inside of that, instead of trying to center the image view in the screen with constraints.
I was able to do this in Visual Studio on my windows desktop. Its frustrating! I also tried, deleting the Storyboard, Added a new one, deleting the View Controller, and adding it back.
I have edited the iOS settings, and moved the assets to Asset Catalogues. Then opened up that Contents. No cigar. Everytime I launch, I get a blue background with my app icon centered in the middle.

I'm having the same issue. I've gone into the project properties and set the three launch images x, x, xyet the iOS Simulator keeps using a "generic" launch screen that is white with the app name and my name on it. I don't have this issue with any old apps -- this is only happening with my new app. Right now you are telling iOS to use the LaunchScreen.
KMullinsI clear that field and the splash screen is showing, but the app is zoomed, all is a bit bigger Took me a while to figure that out too. Command-2 or Command-3 to scale the simulator. KMullinsthanks, that pointed in the right direction. I cleared the dropdown box and that didn't have any effect. But went to Info. Point 2, the screenshot clearly shows the use of the LaunchScreen xib and there's no mention of clearing that field. KMullins and BradWhite - you are both legends.
Thank you!! For the life of me I can't get the launch screens to show at all. They used to work, I changed nothing and they all of a sudden stopped showing. Now no matter what I try they simply do not show.
I've tried the above solutions and there is no change all I get is the 'app name' screen in stead of the image s. What the heck am I missing here? My launchScreen drop down is empty, every resolution images is added and the correct size I triple checked. I don't care about the images, but I can't get approved without them or I wouldn't bother.

I'm having some trouble on showing a launch screen only on my real iPad Mini device. When I run my app, a blue screen is shown instead. I'm using an asset catalog to include the images. When I run on iPhone or on iPad 2 Simulators the launch screen shows perfectly! Inside the Contents. They are:. I create a Storyboard and it works perfectly now.
The simulator is not case sensitive, e. Your iOS device, on the other hand, is case sensitive. Maybe it will help to dublecheck the spelling for all files, and asset catalogues to make sure they are consistent with your info.

Every app must supply a launch screen. To accommodate the screen sizes of different devices and environments, such as multitasking, use an Xcode storyboard to provide a launch screen.
Storyboards are flexible and adaptable, and you can use a single storyboard to manage all of your launch screens. For developer guidance, see Responding to the Launch of Your App.
If you need to know the dimensions of various screen sizes to help you lay out your designs, see Device Screen Sizes and Orientations.Instagram action blocked error
If you include elements that look different when the app finishes launching, people can experience an unpleasant flash between the launch screen and the first screen of the app. Also make sure that your launch screen matches the device's current appearance mode; for guidance, see Dark Mode. Avoid including text on your launch screen. Downplay launch.
People value apps that let them quickly access content and perform tasks. Combined with a fast launch time, this design approach makes your app feel immediately responsive. For a game, the launch screen should transition gracefully into the first screen the game displays. If your game or other immersive app displays a solid color before transitioning to the first screen, you can create a launch screen that displays only that solid color.

We could only use static images as the launch screen.
However, we can't be against Apple's rules. It just sets a static image as the first splash image, then shows our own view controller to play an animated gif image.
At last, show the main content view controller after the animation finished. Hi LandLu and divyagarimellaI am stuck in this issue from last 2 weeksI don't have any idea about swiftcan you please suggest me how can I do it in Xamarin forms c.

About Xamarin Xamarin.For the new iOS 9 splitscreen feature, I added a Launchscreen storyboard which displays an image located in an asset catalogue.
When editing the storyboard the images is properly displayed in Interface Builder, the same goes for devices running iOS 8 or the iOS 9 simulators. The storyboard itself is displayed, just the image is missing. Any idea what the problem here is or if I could debug this any further? I don't see any error messages in the build logs. The image which I want to use inside LaunchScreen but won't be appearing is just displayed fine after App is running.
So I don't think it is a image file's problem. When I switched launch image to other images which I have no intentions to use as the purpose, it works as intended popped up while launching. So it is not a Image View's problem eigther. Here is the strange thing Created a new single view project in Xcode 7 GM. Looking through the device logs, I noticed the following error messages when running the app where the images didn't load in the LaunchScreen:. This is strange, after leaving it roughly a day and coming back, the image is now showing perfectly fine I have been having this issue on and off with iOS9GM, I find sometimes the images will appear sometimes they won't.
Has anyone found a solution or at least a workaround for this bug yet? I had the same problem, and was able to fix it by changing image property of imageView to other and back. Seems you need Image Propety in images. I came over this when I compared projects, and one of my projects did not have this problem and this had Image Property added, and the one with black box did not.
Added Image Property and it works fine. It seems that iOS9 likes images better with image property. You can add one with Preview. This still exists in iOS 9. None of the suggestions above seemed to work.Airpods pro windows 10
Even deleting the app and re-installing from XCode doesn't work. However, changing the bundle ID does work. With no other changes, the existing bundle ID shows no images, but the new bundle ID shows them all correctly.Sena 20s update
I'm doing that as a temporary work-around, since a previous post in this thread suggests that installing the builds via TestFlight doesn't encounter the problem.This article explains how to create an app Launch Screen for all iOS devices, at any resolution and orientation, using a single Unified Storyboard.
Before iOS 8, creating a Launch Screen for an iOS app required the developer to provide an image asset for each of the various device form factors and resolutions in which the app could run.
Since the release of iOS 8, however, it has been possible to use a single Unified Storyboard to create a Launch Screen that looks correct in all cases. This brief walkthrough describes how to create a Launch Screen with either a Storyboard provided by default in a new Project or with a Storyboard added manually to an existing Project. It then demonstrates how to use the iOS Designer to add an Image View and a Label to the Storyboard, to set constraints on those views, and to verify that the Storyboard looks correct for various devices and orientations.
In iOS 8 and laterthe developer can create a special Unified Storyboard to provide the Launch Screen instead of using one or more static launch images. When creating a launch Storyboard in the iOS Designer, use Size Classes and Auto Layout to define different layouts for different display environments. By using Size Classes and Auto Layout, the developer can create a single launch screen that looks good on all devices and display environments.
Add an image to the Assets. Open LaunchScreen. Open the device selection panel on the bottom toolbar and select iPhone 4S and Portrait. Set the Background color of the View Controller's main View.
Select the View by clicking in the middle of the View Controller and adjust the background color using the Properties Pad :. Add constraints to the Image Viewsetting its height and width and centering it horizontally and vertically:. Add constraints to the Labelcentering it horizontally, giving it a height and width, and positioning it a fixed distance vertically from the Image View :.
Test other devices and orientations to verify that the design looks as intended in all scenarios. In cases where adjustments need to be made for a specific device or orientation, use the Edit Traits button to add constraints for specific size classes:. Save the changes to the Storyboard. Run the app on a simulator or device, and the Launch Screen will be visible as the app is launching.
Create a new project. This file will be replaced with a Storyboard in the next step. Create a Storyboard to use as the Launch Screen.
