iOS - local notification - custom vibration or vib

Question

I am trying to build an iPhone app that works like an alarm, I am using UILocalNotification

Problem

• I would like the phone to vibrate for a longer duration. However currently it vibrates only once.

Alternative Approaches

1. Is it possible to use custom vibration patters ?(http://www.pcworld.com/article/242238/how_to_use_custom_vibrations_in_ios_5.html)

2. Is it possible to execute a method, when the push notification is fired ? (but the app might not even be running, and yet it needs to work)

3. Is NSTimer an option ? (but the app might not even be running, and yet it needs to work)

4. Is there any other alternate ?

Answer 1

You cannot change the duration of vibration,or make it,for example,vibrate several times(untill you don't make several notifications).

Only way to make custom vibration is to do it from the app, while it is running, no other way for you.
