title: NativeScript - Angular 2 Custom AppDelegate
body: <p>Is there an Angular 2 way to accomplish a custom AppDelegate like <a href="https://github.com/NativeScript/sample-ios-background-execution/blob/master/app/custom-app-delegate.ts" rel="nofollow noreferrer">this</a> in NativeScript? I've seen examples of how to do this without Angular, I'm just not sure where to register the AppDelegate in Angular 2.</p>
