Thank You

self.navigationItem.hidesBackButton = YES;

When you're done loading,

[self.navigationItem setHidesBackButton:NO animated:YES];

you could use something like this

[self.navigationController setNavigationBarHidden:YES animated:YES];

when you start loading the data, and set it to no when your data is loaded.

Or you could add that code to the viewcontrollers viewWillAppear section and then again show the nav bar once the view is loaded.
