//
SystemSoundID system_id;
//綁定ID 和 URL
AudioServicesCreateSystemSoundID((__bridge CFURLRef) url, &system_id);

//註冊回調
AudioServicesAddSystemSoundCompletion(system_id, NULL, NULL, AudioServicesSystemSoundFinish, NULL);
//播放
AudioServicesPlaySystemSound(system_id);

}

@end

void* __nullable clientData){
AudioServicesRemoveSystemSoundCompletion(ssID);
AudioServicesDisposeSystemSoundID(ssID);//手機靜音的時候無效

}

播放提示音

//註冊回調
AudioServicesAddSystemSoundCompletion(system_id, NULL, NULL, AudioServicesSystemSoundFinish, NULL);
//播放
AudioServicesPlaySystemSound(system_id);

AudioServicesPlayAlertSound(system_id);//手機靜音 播放聲音 並震動
