Setting sounds for local notifications on a 3G iPhone running iOS4

Question

I have successfully scheduled local notifications in my app using the code below:

Class cls = NSClassFromString(@\"UILocalNotification\");

    if (cls != ni         


        

Answer 1

UILocalNotification does not support mp3. It only supports the formats and containers mentioned on the reference page.

Because custom alert sounds are played by the iOS system-sound facility, they must be in one of the following audio data formats:

  Linear PCM
  MA4 (IMA/ADPCM)
  µLaw
  aLaw

You can package the audio data in an aiff, wav, or caf file.
