ios7 - how to transition back to self - ios7

Question

as per the following storyboard, I have a RootViewController (embedded in a TabBarController), which manage many ViewControllers with a vertical menu.
When this RootViewController did load, I check for client authentication, and if not yet authenticated, I switch to a ConnectViewController for remote authentication
#implementation WDURootViewController
....
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
if (!self.client.isAuthorized) {
WDUConnectViewController *cvc = self.connectVC;
[self addChildViewController:cvc];
[self.view addSubview:cvc.view];
[cvc didMoveToParentViewController:self];
}
}
when authentication is successful, I want to come back to the RootViewController...
so in my ConnectViewController, I call back a didConnect() method to notify the RootViewController
#implementation WDUConnectViewController
....
- (IBAction)sendGrantRequest
{
....
[self.client authorizeUser:login password:pwd
onSuccess:^() {
[self.workinOnIt stopAnimating];
[self.connectButton setEnabled:YES];
[(WDURootViewController *)self.parentViewController didConnect];
}
and in the RootViewController, didConnect() method I try to switch the views, in transition from the ConnectViewController to the RootViewController
#implementation WDURootViewController
....
- (void)didConnect
{
[self transitionFrom:self.connectVC To:self];
}
....
- (void)transitionFrom:(UIViewController *)oldC To:(UIViewController *)newC
{
[oldC willMoveToParentViewController:nil];
[self addChildViewController:newC];
[self transitionFromViewController: oldC toViewController: newC
duration: 0.25 options:0
animations: nil
completion:^(BOOL finished) {
[oldC removeFromParentViewController];
[newC didMoveToParentViewController:self];
}];
}
- (WDUConnectViewController *)connectVC {
if (_connectVC == nil) {
UIStoryboard *storyboard = self.storyboard;
_connectVC = [storyboard instantiateViewControllerWithIdentifier:#"WDUConnectViewController"];
_connectVC.client = self.client;
}
return _connectVC;
}
but the transition method is looping... I guess it's not the way to go , what's the simplest way?

Answer 1

I got it , just updating the didConnect() method in the RootViewController
- (void)didConnect
{
[self.connectVC willMoveToParentViewController:nil];
[self.connectVC.view removeFromSuperview];
[self.connectVC removeFromParentViewController];
[self awakeFromNib];
}
