Use the setBarTintmethod to change the bar color. The default iOS colors are ok, but no app is complete without a nice, pretty custom Navigation Bar color. tHidesBackButtonAnimated(true, false) Ĭhanging the Navigation Bar Background Color get the view controller navigation item var controller = frameModule.topmost().ios.controller Hiding the back button requires getting an instance of the UIViewController’s navigation item, and invoking the setHidesBackButtonAnimated method. This is not ideal as the user could then back into the OAuth process and the app would break. By default, that feed page displays a back button. In the example used here, the user logs in to Instagram using OAuth and is then redirected to the feed page. Sometimes it may be desirable to hide the back button. Simply use the page.iosapplication object which exposes a title property. hide the navbarįrameModule.topmost().ios.navBarVisibility = "never" įrameModule.topmost().ios.navBarVisibility = "always" Ĭhanging the title is really easy. The frame module reference allows for easy showing/hiding of the Navigation Bar at any time and on any page. Var controller = frameModule.topmost().ios.controller On each subsequent view, you will see it including a “ This means that on the first view, you won’t see a Navigation Bar at all. Any view that is navigated to after that is pushed onto the navigation queue using a UINavigationController. NativeScript treats the initial page that is loaded as the root view controller.
Customizing the Color of the Back Button.Changing the Navigation Bar Background Color.I really enjoyed the way the post was laid out, so I’m going to use roughly the same format here to talk about the iOS Navigation Bar / Status Bar in NativeScript: It’s a fantastic article that goes through much of what can be done to the iOS Navigation Bar and Status Bar from an Objective-C point of view. In the process of learning to customize the Navigation Bar, I took a lot of inspiration from this post by Simon NG on AppCoda. However, most of the items that I will cover here can also be implemented for Android. While NativeScript is a cross-platform framework, these tweaks apply specifically to iOS. In this article, I’ll go over a few of the more common tweaks that you might need to make to the Navigation Bar or Status Bar. But fear not! I have braved the treacherous waters of StackOverflow and the Objective-C docs and emerged, victorious and unscathed. NativeScript has a Navbar component on the roadmap, but for now, it requires some knowledge about the underlying iOS implementation of UINavigationControllers, UIViewControllers and the like.

I read that the email form’s parameters are expressly prohibited by Apple from change and yet, here it is getting changed inadvertently by manipulating my own view controller’s parameters.As I’ve been learning more and more about NativeScript, one of the first tasks that I really dove into was learning how to customize the Navigation Bar for an iOS app. Sometimes, the “Send” and “Cancel” buttons are also white and unreadable. This results in an unreadable title in the mail view because of the white background (even worse if there is no shadow). Would present the mail view but with the changed navigation bar parameters.
