iphone - Choose custom sound for local notifications

Question

posted Oct 17, 2021 in Technique[技术] by 深蓝 (71.8m points)

How do you change the sound that plays for local notifications? I use the code below to play the default sound:

notif.soundName = UILocalNotificationDefaultSoundName;

So, I tried this below, and it didn't work. What should I do? Thanks for your help!

notif.soundName = @"sound.caf";

You can convert from wav and mp3 using:

afconvert -f caff -d LEI16@44100 -c 1 in.wav out.caf
