Hello,

I tried this approach but its not working with all pages:

let self=this;
  browser.on('exit').subscribe(function(event) {
    if (self.platform.is('ios')) {
    var IOSHeader = document.getElementById('HeaderMarginTop');
    self.renderer.setElementStyle(IOSHeader, 'top', '20px');
  }
  });

Please help!
