Multiple entry points to a storyboard

问题

I need to make a set of decisions in the AppDelegate on launch - depending on the outcome of those decisions I need to go to specific parts of the storyboard.

So my question is - WITHOUT using any nav or tab controllers, how do I go to a specific part of a storyboard?

OR

Is the only supported option having multiple storyboards - for each of the 'outcomes' and then loading those as required?

Thanks

回答1:

Give each of your ViewControllers a separate ID, and then instantiate the required one with:

UIViewController *initialVC = [storyboard instantiateViewControllerWithIdentifier:@"<identifier>"];

回答2:

Give each ViewController a unique identifier in the storyboard. Then in the appDelegate:

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
    UIViewController *vc = [storyboard instantiateViewControllerWithIdentifier:@"PUT_UNIQUE_ID_HERE"];
    //DO WHAT YOU WANT WITH YOUR VIEWCONTROLLER
   //Example:Set it as the root view of the app window...
