You just change setting of you device

Follow these steps

1) Go to device settings.

2) Find your application in setting list.

3) And give camera access permission to your application (under allow "app name" to access).

I got solution. I just replace below code

[App_Delegate.window.rootViewController 
        presentViewController:picker 
        animated:YES 
        completion:nil];

with this code

[self presentViewController:picker animated:YES completion:NULL];
