Iphone Multiple localnotification

I face a very weird experience, when i receive multiple notification and then didn't response to it immediately. After a while, i pressed the view button and it open my application and show black scre开发者_开发知识库en.

BTW, the application is running at background when i click the view button and it also doesn't trigger didReceiveLocalNotification.

Does anyone know what is the problem?

Thanks

When your application is running in background and if notification come, then it will call applicationFinishLauchingwithOptions Method. So write your logic in that part.
