    ios - Silent failure when scheduling a background task - Stack Overflow

    programmeradmin2浏览0评论

    I am working on adding some background processing.

    I register for background tasks and then schedule a single task.

    I am seeing the following results:

    • Nothing fails or throws during the setup
    • The task doesn’t execute
    • The pending tasks list is empty.

    I have:

    • Added the Background processing capability
    • Added the Permitted background task scheduler identifiers into the Info.plist
    • beginBackgroundMonitoring() is called during app launch
    • Tested exclusively on a real device
    • Tried running e -l objc -- (void)[[BGTaskScheduler sharedScheduler] _simulateLaunchForTaskWithIdentifier:@"com.myApp.task"] which also doesn’t trigger it
    <key>UIBackgroundModes</key>
<array>
    <string>processing</string>
</array>
<key>BGTaskSchedulerPermittedIdentifiers</key>
<array>
  <string>com.myApp.task</string>
</array>

    I see the following in the logs:
