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

There could be a couple of reasons:

1. Is your sound file included in your bundle? (most likely, seeing as it works on the simulator)
2. The Apple documentation says to not use compressed audio formats. See the link here. The reason for this being that the iPhone hardware can only play one compressed audio file at a time, and so it is not recommended to use one for the alarm as well, in case the user is already listening to a song from iTunes.
