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 thedeveloper to provide an image asset for each of the various device formfactors and resolutions in which the app could run. Since the release of iOS8, however, it has been possible to use a single Unified Storyboard tocreate a Launch Screen that looks correct in all cases.

Just press the Win-left or right arrow keyboard shortcut inside a Modern app, and it'll snap to fill half of the screen. You can then move the slider in the middle of the screen to resize it to as small as 1/3rd of your screen. It's possible to connect a second (or third) display to your Mac. Here's how to use a second screen with your Mac or MacBook, including finding the right adapter and cable. Jul 05, 2010  Resizing Windows That Are Off Screen in Mac OS X.

Of course, this is assuming.

This brief walkthrough describes how to create a Launch Screen with either aStoryboard provided by default in a new Project or with a Storyboard addedmanually to an existing Project. It then demonstrates how to use the iOSDesigner to add an Image View and a Label to the Storyboard, to setconstraints on those views, and to verify that the Storyboard looks correctfor various devices and orientations.

Managing Launch Screens with Storyboards

In iOS 8 (and later), the 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.

  1. In Visual Studio for Mac, create a new project by selecting File > NewSolution and then choosing Single View App:

    • By default, a new Project includes a LaunchScreen.storyboard file thatdefines the Launch Screen interface.
    • To instead add a Launch Screen Storyboard to an existing project,right-click on the project name in the Solution Pad and chooseAdd > New File.. and then select Launch Screen:
    • Name the file LaunchScreen or another name of your choosing.
  2. Configure the Project to use the appropriate Storyboard for its LaunchScreen:

    • Double-click the Info.plist file in the Solution Pad to openit for editing.
    • In the Launch Images section, make sure that Launch Screen isset to the name of the appropriate Storyboard:
    • By default, a new Project is configured to useLaunchScreen.storyboard as its Launch Screen.
  3. Add an image to the Assets.xcassets Asset Catalog so that it isavailable for use on the Launch Screen. For more information, see theAdding Images to an Asset Catalog Image Setsection of the Displaying an Imageguide.

  4. Open LaunchScreen.storyboard for editing by double-clicking it in theSolution Pad.

  5. Choose a device and orientation on which to preview the Launch ScreenStoryboard in the iOS Designer. Open the device selection panel on thebottom toolbar and select iPhone 4S and Portrait.

    • Note that selecting a device and orientation only changes how the iOSDesigner previews the design. Regardless of the selection made here,newly added constraints are applied across all devices andorientations unless the Edit Traits button has been used tospecify otherwise.
  6. Set the Background color of the View Controller's main View. Selectthe View by clicking in the middle of the View Controller and adjust thebackground color using the Properties Pad:

  7. Add an Image View to the Launch Screen and set its source Image:

    • Drag an Image View from the Toolbox Pad to the center of theView.
    • With the Image View selected, in the Widget section of theProperties Pad set the Image property to the Image Set alreadyadded to the Assets.xcassets Asset Catalog. Reposition and sizethe Image View as required:
  8. Add a Label below the Image View and use the Properties Padto set its attributes:

  9. Switch to Constraint Editing Mode by using the right-hand button in theConstraints Toolbar:

  10. Add constraints to the Image View, setting its height and width andcentering it horizontally and vertically:

    • For more details on how to add constraints, see Auto Layout with theXamarin Designer for iOS.
  11. Add constraints to the Label, centering it horizontally, giving it aheight and width, and positioning it a fixed distance vertically fromthe Image View:

  12. Test other devices and orientations to verify that the design looks asintended in all scenarios. In cases where adjustments need to be madefor a specific device or orientation, use the Edit Traits button toadd constraints for specific size classes:

  13. Save the changes to the Storyboard. Run the app on a simulator ordevice, and the Launch Screen will be visible as the app is launching.

  1. Create a new project. In Visual Studio, select File > New > Project > Visual C# > iPhone & iPad > iOS App (Xamarin):

    Select the Single View App template, and then click OK:

  2. If Resources > LaunchScreen.xib exists in the Solution Explorer,delete it by right-clicking on the file and choosing Delete. Thisfile will be replaced with a Storyboard in the next step.

  3. Create a Storyboard to use as the Launch Screen. In the SolutionExplorer, right-click on the Project and choose Add > New Item..followed by Empty Storyboard. Name this StoryboardLaunchScreen.storyboard and click Add:

  4. Configure the Project to use LaunchScreen.storyboard as its LaunchScreen Storyboard:

    • Double-click the Info.plist file in the Solution Explorer toopen it for editing.
    • On the Visual Assets tab, set Launch Screen toLaunchScreen.
  5. Add an image to an Asset Catalog in the Project so that it is availablefor use on the Launch Screen:

    • In the Solution Explorer, right-click on Asset Catalogs andselect Add Asset Catalog. Name this new Asset Catalog Assets:
    • Add a new Image Set to the Assets Asset Catalog, as described inthe Adding Images to an Asset Catalog Image Setsection of the Displaying an Imageguide.
  6. Open LaunchScreen.storyboard for editing by double-clicking it in theSolution Explorer. Multilingual app toolkit for mac free.

    • To edit a Storyboard file, Visual Studio needs an activeconnection to a Mac build host. See the Connecting to the Macguide for details.
  7. Choose a device and orientation on which to preview the Launch ScreenStoryboard in the iOS Designer. Open the device selection panel on thebottom toolbar and select iPhone 4S and Portrait:

    • Note that selecting a device and orientation only changes how the iOSDesigner previews the design. Regardless of the selection made here,newly added constraints are applied across all devices andorientations unless the Edit Traits button has been used tospecify otherwise.
  8. Add a View Controller to the Storyboard by dragging one from theToolbox onto the design surface:

  9. Set the Background color of the View Controller's main View. Selectthe View by clicking in the middle of the View Controller and adjust thebackground color using the Properties Window:

  10. Add an Image View to the Launch Screen and set its source Image:

    • Drag an Image View from the Toolbox to the center of the View.
    • With the Image View still selected, in the Widget section ofthe Properties Window set the Image property to the Image Setalready added to the Assets Asset Catalog. Reposition and size theImage View as required:
  11. Add a Label below the Image View:

    • Drag a Label from the Toolbox onto the design surface, placingit below the Image View.
    • Set attributes for the Label using the Properties Window:
  12. Switch to Constraint Editing Mode by using the right-hand button in theConstraints Toolbar:

  13. Add constraints to the Image View, setting its height and width andcentering it horizontally and vertically:

    • For information about adding constraints, see Auto Layout with the Xamarin Designer for iOS.
  14. Add constraints to the Label, centering it horizontally, giving it aheight and width, and positioning it a fixed distance vertically fromthe Image View:

  15. Test other devices and orientations to verify that the design looks asintended in all scenarios. In cases where adjustments need to be madefor a specific device or orientation, use the Edit Traits button toadd constraints for specific size classes:

  16. Save the changes to the Storyboard. Run the app on a simulator ordevice, and the Launch Screen will be visible as the app is launching.

Note

A Storyboard used as a Launch Screen must include onlysimple, built-in UI elements and cannot do any calculations or derivefrom a custom class.
