Is it possible to setup a default navOptions for the Navigation Controller?
Why I ask this is, I know that the individual function of a navController can apply the navOptions, e.g.:
this.navController.push (NewPage, null, navOptions);
However, I cannot find out how to apply the navOptions for the Back Button after I pushed a page, and it will be great if I can even control all the navigation actions to use the same navOptions! Thanks!
