从appDelegate monoTouch推送到viewController

Question

I am trying to setup a Getting started viewController. In the appDelegate I want to create a if condition that checks for a NSUserDefaults Like this:

public override bool FinishedLaunching (UIApplication application, NSDictionary launchOptions)
        {

            if (NSUserDefaults.StandardUserDefaults.StringForKey ("LaunchWatcher") != null) {



            } else {


            }


            return true;
        }

If LaunchWatcher is not null, appDelegate should push to NewTrackTraceViewController. If null then to TrackTraceViewController. How can I do this using C#? What would be the correct code to push to the viewcontroller?

Something like this:

if (NSUserDefaults.StandardUserDefaults.StringForKey ("LaunchWatcher") != null) {

this.PresentViewController(NewTrackTraceViewController, animated, null);

            } else {

this.PresentViewController(TrackTraceViewController, animated, null);
            }

Answer 1

您必须先构造视图控制器，然后再导航控制器，并将其分配给窗口。

Answer 2

Take a look here:

Monotouch navigate from splash screen

Its basicly what you have to do. Just use the topviewcontroller.
