ios - How to only allow certain URLs in app -

-

is there way allow app load urls? thinking there exception domains in app transport security settings, except not allowing arbitrary loads url, rather allow urls , block others, whether or not https/http. thanks

you can use in appdelegate:

optional func application(_ app: uiapplication,               openurl url: nsurl,               options options: [string : anyobject]) -> bool {     //return true or false depending on if want      //this application open url. }

in comments mention using in single uiwebview. in case can following:

func webview(webview: uiwebview, shouldstartloadwithrequest request: nsurlrequest, navigationtype: uiwebviewnavigationtype) -> bool {     let url = request.url      return handlerequest(url) }  @available(ios 8.0, *) func webview(webview: wkwebview, decidepolicyfornavigationaction navigationaction: wknavigationaction, decisionhandler: (wknavigationactionpolicy) -> void) {     let request = navigationaction.request;     let url = request.url      if(handlerequest(url))     {         decisionhandler(wknavigationactionpolicy.allow)     }     else     {         decisionhandler(wknavigationactionpolicy.cancel)     } }

that bit of code handles both uiwebview , wkwebview.
