You can disable the left navigation button from inside an UIViewController like this, without using any IBOutlet:

self.navigationItem.leftBarButtonItem.enabled = NO;

To disable the right navigation button:

self.navigationItem.rightBarButtonItem.enabled = NO;

Swift3

self.navigationItem.rightBarButtonItem?.isEnabled = false
