Did you verify this is a real problem by searching Stack Overflow?

Yep :) http://stackoverflow.com/questions/36989709/nativescript-cannot-change-ios-status-bar-color

Tell us about the problem

As of the 2.0 release, I am no longer able to change the iOS status bar’s text color.

Which platform(s) does your issue occur on?

iOS

Please provide the following version numbers that your issue occurs with:

• CLI: 2.0.0
• Cross-platform modules: 2.0.0
• Runtime(s): 2.0.0

Please tell us how to recreate the issue in as much detail as possible.

Use the following main-page.xml:

<Page loaded="loaded">
    <Page.actionBar>
        <ActionBar title="Whatever"></ActionBar>
    </Page.actionBar>
</Page>

And the following main-page.js:

var frameModule = require("ui/frame");
exports.loaded = function(args) {
    var page = args.object;
    if (page.ios) {
        var navigationBar = frameModule.topmost().ios.controller.navigationBar;
        navigationBar.barStyle = UIBarStyle.UIBarStyleBlack;
    }
};

This code changed the iOS status bar to use white text with version 1.7.1 of the modules, but now it has no effect.

Thanks.
