IOS手机震动和铃声设置

做app的时候经常会遇到收到告警消息后,手机要震动下或播放个声音.以下记录了相关代码
1.手机震动(在iphone有作用,在ipad上没有作用)
AudioServicesPlaySystemSound(kSystemSoundID_Vibrate);
2.播放铃声
SystemSoundID soundId;
NSString *path = [[NSBundle mainBundle]pathForResource:@“ring”1 ofType:@"aiff"];
AudioServicesCreateSystemSoundID((__bridge CFURLRef)[NSURL fileURLWithPath:path], &soundId);
AudioServicesPlaySystemSound(soundId);
