Objective : A button in iOS native app when clicked opens a url (webpage) in native browser (safari or other, not UiWebView as it no longer supports html file control api) then, using javascript in the opened webpage, close that browser window so revealing the app again.
Opening the URL from the native app is not an issue: How to launch safari and open URL from iOS app?
Closing that resultant browser window is an issue, is there a way to accomplish this?
