如何以编程方式确定 iPhone 是否处于礼貌模式？有没有办法判断耳机是否已连接？

编辑:在世界某些地方，这也称为静音模式。

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];
