Ios Local Notification System Sound
This is a long post so let s start easy by importing the new notifications framework.
Ios local notification system sound. In ios tvos and watchos apps must have authorization to display alerts play sounds or badge the app s icon in response to incoming notifications. Behavior is the same with either new unusernotifications or deprecated uilocalnotifications. To choose when you want most notification previews to appear tap show previews then select an option always when unlocked or never. The first load of an app with local notification custom sounds works correctly.
Requesting authorization puts control of those interactions in the hands of the user who can grant or deny your request. For local notifications assign the sound object to the sound property of your unmutable notification content object. Go to settings notifications. For a remote notification assign the name of your sound file to the sound key in the aps dictionary.
When local notifications are displayed outside of the app the device vibrates and the sound specified by uilocalnotificationdefaultsoundname is played. Behavior only occurs on ios 10. You can turn app notifications on or off have notifications play a sound choose how and where you want app notifications to appear when your device is unlocked and more. To do this you need to.
The catch is it only works if the device is connected to the internet. When a notification comes in ios displays the notification in the form of on screen alerts or sounds and it s up to the user to decide whether to launch the application. Ios localnotification is a wrapper around the uilocalnotification class found in the apple uikit framework and is only available on iphone ipad ipod touch. When the app is updated by xcode testflight or app store the app plays only the default sound.
Until ios 12 notifications would not show if the app was in the foreground however from ios 12 you are able to show notifications in both the foreground and background. You can also use a notification service app extension to add a sound file to a notification shortly before delivery. Instead the didreceivelocalnotification method is called in my app delegate and i mimic the local notification dialog by displaying a uialertview with the reminder text.
