Question

How can i use local notification with sound but without vibration?
And how can i use it conversely, with vibration but without sound?

edit:
while i read, i found one solution for vibration without sound:
(not appropriate to localnotifications in my case)
a) AudioServicesPlayAlertSound(kSystemSoundID_Vibrate);
b) AudioServicesPlaySystemSound(kSystemSoundID_Vibrate);
and as variant play silent sound, that will give vibration without sound effect.

我无法使用声音而不振动(我们谈论的是本地通知)。对不对?

Answer 1

我如何使用本地通知声音但没有振动?

如果通知中指定了声音(取决于用户的设置,他们可能已经关闭了振动),就会触发振动。我认为目前没有任何方法可以让音效通知发生振动。

我怎样才能用它来反转, 振动,但没有声音?

您的猜测是正确的, 此选项很容易使用静音文件实现( 确保不到30秒, 通知API所施加的限制 ) 。
