Specify a Custom Notification Sound

This feature uses a sound included in your mobile app as a custom audio signal when a push message arrives on the mobile device.

  1. Add a file named custom.caf to your project. The cloud push payload looks for a file named custom.caf.
  2. Add the custom.caf audio file to the Copy Bundle Resources folder for your app.
  3. To prevent Xcode from using cached files, perform a clean build folder in Xcode. In the Product menu, hold the Option key and select Clean Build Folder.
  4. Ask the marketer to enable custom sound on the MobilePush Administration page in Marketing Cloud.
