I have this situation:
I have an iWatch app that has a root WKInterfaceController and when it fires a particular event I present another WKInterfaceController in this way:
WKInterfaceController * rootC = [WKExtension sharedExtension].rootInterfaceController;
[rootC presentControllerWithName:@"testController" context:nil];
My problem is that when it fires a particular event that I catch in InterfaceController, I have to show an alert in 'testController'. But from that root controller I can't get the visibile controller (like in iPhone project).
You can get visible controller by using WKExtension property:
@property(nonatomic, readonly) WKInterfaceController *visibleInterfaceController;
