Three ways to make phone calls from iOS

1, this method, call the end of the phone back to the original application, will stay in the address book, and is directly dialed, not pop-up hints

var string = "Tel:" + "136XXXXXXXX" uiapplication.sharedapplication (). OpenURL (Nsurl (string:string)!)

2, this method, after the call will return to the original program, will also pop up hints, recommend this

var string = "Tel:" + "136XXXXXXXX" var Callwebview:uiwebview = UIWebView () callwebview.loadrequest (Nsurlrequest (URL: Nsurl (string:string))) Self.view.addSubview (Callwebview)

3, this method will also go back to the original program (note here Telprompt), will also pop-up hints

var string = "telprompt://" + "136XXXXXXXX" uiapplication.sharedapplication (). OpenURL (Nsurl (string:string)!)
