Answer 1

NSURL *url = [NSURL URLWithString:@"http://www.pacdv.com/sounds/people_sound_effects/c-c-2.mp3"]; 
NSData *soundData = [NSData dataWithContentsOfURL:url];
NSString *documents = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0]
NSString *filePath = [documents stringByAppendingPathComponent:@"sound.caf"];
[soundData writeToFile:filePath atomically:YES];
