Many question regarding Message Center

Follow

Hi,

I'm using iOS SDK on my iOS app.

i. Is content of Message Center saved locally?
ii. Can I retrieve messages without using the out-of-the-box message center? 
iii. I would like to pull the message from Message Center manually and display them on custom UI. Am I doing it wrong?

    [[[UAirship inbox] messageList] retrieveMessageListWithSuccessBlock:^{

        NSArray *msgs = [[UAirship inbox] messageList].messages;

        for(int i=0;i< [msgs count];i++) {

            UAInboxMessage *msg = [msgs objectAtIndex:i];

            NSLog(@"title: %@", msg.title);

            NSLog(@"read?: %@", msg.unread ? @"Yes" : @"No");

            NSLog(@"rawMsg:%@", msg.rawMessageObject);
      }

    } withFailureBlock:^{        
    }];

Thank you,

Regards,
Felix
