To do the refresh of the view do not call viewWillAppear if the view is already displayed. What you want to do is the following:

When ConnectionDidFinishLoading method is triggered post a notification

In your viewController observe for this notification. You do it by adding this code to your init or viewDidLoad method

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(refreshView:) name:@"refreshView" object:nil];

Now implement -(void)refreshView:(NSNotification *) notification method in your viewController to manage your view to your liking.
