This is my config xml (adjust your zip package before building with phonegap):
<!--
On iOS, the statusbar is transparent by default and is drawn over the top
of our app.
-->
<preference name="StatusBarOverlaysWebView" value="false" />
<preference name="StatusBarBackgroundColor" value="#000000" />
<preference name="StatusBarStyle" value="lightcontent" />
<preference name="DisallowOverscroll" value="true" />
<preference name="KeyboardDisplayRequiresUserAction" value="false" />
<!-- speciaal voor iOS-->
<preference name="EnableViewportScale" value="false"/>
<gap:plugin name="cordova-plugin-statusbar" source="npm" version="1.0.1" />
