Answer 1

也许你不在Xcode项目中添加声音文件（* .caf）：Build Phases / Copy Bundle Resources。

Answer 2

I have done notification successfully with the code below.

UILocalNotification *localNotif = [[UILocalNotification alloc] init];
            if (localNotif == nil)
                return;
            /*  NSDateFormatter *formatDate=[[NSDateFormatter alloc]init];
             [formatDate setDateFormat:@"MM/dd/yyyy"];
             [formatDate setTimeZone:[NSTimeZone systemTimeZone]];
             NSDate *strDate=[formatDate dateFromString:txtDate.text];
             */
            localNotif.fireDate = itemDate;
            //localNotif.timeZone = [NSTimeZone systemTimeZone];

            NSLog(@"the item date is %@",localNotif.fireDate);

            // Notification details
            //localNotif.alertBody = [eventText text];]
            localNotif.alertBody=strEvent;
            // Set the action button
            localNotif.alertAction = @"View";


            //localNotif.soundName = @"Acoustic Noodling 01.caf";
            localNotif.soundName=@"alarm1.aif";

About playing custom sounds in Local notifications

Make sure the sound is actually in your app's bundle, is in the correct format (linear PCM or IMA4

Assume that notification is an object of type UILocalNotification.

notification.soundName = @"sound.caf";

If this doesn't work initially then you may refer to this post and there in refer to This Answer That tells us to use sound file of the correct format (ie either Linear PCM or IMA4).

Answer 4

Just use relative path of your file rather than providing absolute or full path.

For example:

localNotification.soundName = @"../Documents/recordedFileName.caf";

Also, keep in mind that recordDuration of file should be less than or equal to 29 seconds.

That's it, hope that answered.
