UILocalNotification play sound from app documents

问题

I know that UILocalNotification supports soundName only from app bundle, but I saw program that plays my recorded sound in Notification, even if program is closed. How to implement it? Any ideas is very important for me..

回答1:

A surefire way to get an NSURL to the application documents directory is like this...

NSURL *documentsDirectoryURL = [[[NSFileManager defaultManager] URLsForDirectory:NSDocumentDirectory inDomains:NSUserDomainMask] lastObject];

Then you can get an NSURL reference to your sound file like this...

NSURL *soundURL = [documentsDirectoryURL URLByAppendingPathComponent:@"sound.caf"];

If you need a string representation of the path to the resource at that URL you can obtain it like this...

NSString *pathRepresentation = [soundURL absoluteString];

just setup relative path like this

notify.soundName = @"../Documents/blabla.caf"
