Three ways to call 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

Nsmutablestring * str=[[nsmutablestring alloc] initwithformat:@ "tel:%@", @ "000000000"];

NSLog (@ "str======%@", str);

[[UIApplication sharedapplication] Openurl:[nsurl Urlwithstring:str]];

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

Nsmutablestring * str=[[nsmutablestring alloc] initwithformat:@ "tel:%@", @ "00000000000"];

UIWebView * Callwebview = [[UIWebView alloc] init];

[Callwebview loadrequest:[nsurlrequest Requestwithurl:[nsurl Urlwithstring:str]];

Tip: Do not add WebView to Self.view, if added will obscure the original view

Lazy Loading

if (_webview = = nil) {

_webview = [[UIWebView alloc] init];

//    }

NSLog (@ "%p", _webview);

//

Nsurl *url = [Nsurl urlwithstring:@ "tel://xxxxxxx"];

Nsurlrequest *request = [Nsurlrequest Requestwithurl:url];

//

[_webview Loadrequest:request];

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

Nsmutablestring * str=[[nsmutablestring alloc] initwithformat:@ "telprompt://%@", @ "000000000"];

NSLog (@ "str======%@", str);

[[UIApplication sharedapplication] Openurl:[nsurl Urlwithstring:str]];
