  3. Launch the installed application on an iOS device like iPhone or iPad.
  4. The screen goes blank for 5-6 seconds after which the branding icon is displayed on the whole screen.


Root Cause



A defect in Pegasystems’ code or rules is identified as root cause of the issue. If we create custom application install splash screen without pega logo element then animateOnLoadScreen function fails which results in splash screen never being hidden.

Follow the below steps:
  1. Apply HFix-34176.
  2. Delete the Pega Temp Directory, extract marker file and restart the application server.
  3. Delete the previously installed mobile application from the iOS device.
  4. Ensure that all the branding assets used for building the mobile application are in place.
  5. Rebuild the mobile application after enabling splash screen (set in custom.properties present in assets.zip file).
    container.splashScreenEnabled=true
  6. Install the updated mobile application on the iOS device.
