I make an App with my own style. So i use Modalto show the menu list. and i need Modal on every pages. But i cant use Nav:NavController on app.ts. This the way i tried.
constructor(platform: Platform,Nav:NavNavController) {}
and i got No provider for NavController!
Then i try this @ViewChild('nav') nav: NavController;
When press button to show the modal i got Cannot read property 'present' of undefined
for the line i code this.nav.present(modal);
Anyone help me please. Thanks you and sorry for my bad english.
