i have app button suppose open facebook page. checks see if user has facebook installed , should open page in app. if not installed, opens page safari. not working however. suspect has wrong address it, if user has facebook installed:

the problem format of facebook url notice format. use extension open urls. provide array of urls in order want them try opened , tries first 1 first , if fails goes second 1 , on:

extension uiapplication {     class func tryurl(urls: [string]) {         let application = uiapplication.sharedapplication()         url in urls {             if application.canopenurl(nsurl(string: url)!) {                 application.openurl(nsurl(string: url)!)                 return             }         }     } }

and use:

uiapplication.tryurl([             "fb://profile/116374146706", // app             "http://www.facebook.com/116374146706" // website if app fails             ])
