Abstract: This article details the orientation requirements for iPad Multitasking support in iOS 9, analyzes common errors, and provides solutions to opt out by setting the UIRequiresFullScreen key. It includes implementation steps via Info.plist or Xcode interface, along with key considerations.

Problem Background

In iOS 9, Apple introduced the iPad Multitasking feature, allowing apps to run in split-screen mode for enhanced multitasking efficiency. To support this, apps must handle all four interface orientations: portrait (UIInterfaceOrientationPortrait), portrait upside down (UIInterfaceOrientationPortraitUpsideDown), landscape left (UIInterfaceOrientationLandscapeLeft), and landscape right (UIInterfaceOrientationLandscapeRight). If an app only supports partial orientations, such as only portrait and portrait upside down, when building with Xcode 7 GM and submitting to iTunes Connect, an error may occur indicating missing required orientations. A sample error is: Invalid Bundle. iPad Multitasking support requires these orientations: 'UIInterfaceOrientationPortrait,UIInterfaceOrientationPortraitUpsideDown,UIInterfaceOrientationLandscapeLeft,UIInterfaceOrientationLandscapeRight'. Found 'UIInterfaceOrientationPortrait,UIInterfaceOrientationPortraitUpsideDown' in bundle 'com.bitscoffee.PhotoMarks.iOS'. This blocks the normal app review process.

Solution

To resolve this issue, developers can opt out of iPad Multitasking support by setting the app to full-screen mode. This is achieved by adding the UIRequiresFullScreen key to the Xcode project's Info.plist file and setting it to the Boolean value YES. After opting out, the app is no longer subject to multitasking orientation requirements but will run only in full-screen mode.

Implementation Steps

Method 1: Modifying via Info.plist File

  1. Open the Xcode project, locate and select the Info.plist file in the project navigator.
  2. Add a new row, set the key name to UIRequiresFullScreen, choose Boolean as the type, and set the value to YES. In XML format, this is equivalent to adding <key>UIRequiresFullScreen</key><true/>.
  3. Save the file and rebuild the project to ensure changes take effect.

Method 2: Setting via Xcode Graphical Interface

  1. In Xcode, select the project target and navigate to the General tab.
  2. In the Deployment Info section, find the "Requires Full Screen" checkbox and check it. This automatically updates the Info.plist file in the background by adding the UIRequiresFullScreen key.
  3. After checking, verify that project settings are synchronized and rebuild to apply changes.

Considerations

Setting UIRequiresFullScreen to YES opts the app out of iPad Multitasking support, meaning users cannot use the app in split-screen mode. This may impact user experience, especially on larger devices like iPad Pro. Therefore, before deciding to opt out, developers should assess the app's functional requirements and target audience. Additionally, it is recommended to thoroughly test the app's orientation settings and compatibility before submission to avoid other potential issues. If the app plans to support multitasking in the future, consider gradually adding required orientation support and managing configurations through conditional compilation or runtime checks.
