问题:

I want to hide the back button from my Apple Watch app from the status bar.

I used the programmable segue to navigate. But I want to to hide/disable the back button. Is it possible?

回答1:

This is how you do it:

WKInterfaceController.reloadRootControllersWithNames(
     ["myInterfaceController"], contexts: []
)

Where myInterfaceController is the identifier of the destination Interface Controller.

Thanks to Harvant for the pointer.

If you check the docs for WKInterfaceController, you'll see there's no API to accomplish what you're looking for: https://developer.apple.com/library/prerelease/ios/documentation/WatchKit/Reference/WKInterfaceController_class/

The best you can do is change the text of the title/button or adjust the tint color.

回答3:

You can present an interface controller modally using the method presentControllerWithName. Then, in the interface controller called, just set the title with the method setTitle.
