SFSafariViewController *safari = [[SFSafariViewController alloc]initW         


        

Answer 1

I was able to achieve this affect using invisible child view controller:

_safariViewController = [[SFSafariViewController alloc] initWithURL:_requestURL];
_safariViewController.delegate = self;
_safariViewController.view.userInteractionEnabled = NO;
_safariViewController.view.alpha = 0.0;
[_containerViewController addChildViewController:_safariViewController];
[_containerViewController.view addSubview:_safariViewController.view];
[_safariViewController didMoveToParentViewController:_containerViewController];
_safariViewController.view.frame = CGRectZero;
