You can add this code on your AppDelegate.cs inside FinishedLaunching method after LoadApplication (new App ()); on iOS Project:

UIApplication.SharedApplication.StatusBarHidden = true;

also add this on your info.plist:

<key>UIViewControllerBasedStatusBarAppearance</key>
<false/>

Go to Info.plist file in your iOS project
Click Source and Hover on one of those lines and a (+) and (-) button will show up. Click the plus button to add new key
Type in start with capital V and automatically the first choice will be View controller-based status bar appearance. Add that as the KEY.
Set the VALUE to "No" Now you can still see the time alone
Then Click again the plus button to add new key
Now choose Status bar is initially hidden and add key "Yes"

In case of you want to hide programatically for each page. You have to create custom renderer for each Forms Page with UIViewController.

In UIViewController, you can override method like below

public partial class CustomViewController : UIViewController
{
      public override bool PrefersStatusBarHidden()
        {
            return true;
        } 
}

Goto info.plist

Just check the HideStatusBar
