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.
- Add a file named custom.caf to your project. The cloud push payload looks for a file named custom.caf.
- Add the custom.caf audio file to the Copy Bundle Resources folder for your app.
- 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.
- Ask the marketer to enable custom sound on the MobilePush Administration page in Marketing Cloud.
