Multiple entry points to a storyboard

Question

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

Answer 1

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...

Answer 2

为每个ViewControllers分配一个单独的ID，然后使用以下命令实例化所需的ID：

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