上似乎有一个例子

转载自Narender Mugdal：

CFStringRef route;
UInt32 propertySize = sizeof(CFStringRef);
AudioSessionInitialize(NULL, NULL, NULL, NULL);
AudioSessionGetProperty(kAudioSessionProperty_Audi oRoute, &propertySize, &route);
NSString *outputString = (NSString*)route; 
//NSLog(@"%@", outputString);
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"" message: outputString delegate:self cancelButtonTitle:@"ok" otherButtonTitles:nil];
[alert show];
[alert release];
