方法一:不彈出提示直接撥打

NSMutableString *str=[[NSMutableStringalloc]initWithFormat:@"tel:%@",@"電話號碼"];

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:str]];

方法二:會彈出提示

NSMutableString *str=[[NSMutableStringalloc]initWithFormat:@"tel:%@",@"電話號碼"];

UIWebView *callWebview = [[UIWebViewalloc]init];

[callWebviewloadRequest:[NSURLRequestrequestWithURL:[NSURLURLWithString:str]]];

[self.view addSubview:callWebview];

方法三:會彈出提示

NSMutableString* str=[[NSMutableString alloc]initWithFormat:@"telprompt://%@",@"111"];

 [[UIApplication sharedApplication]openURL:[NSURL URLWithString:str]];

以上是正常的三種撥號方式,會有卡頓,網路上好多都是這種答案。

博主機智的想到了如何不讓其卡頓,使用者體驗完美的方案:

方案四之終極撥號方式:

NSMutableString *str=[[NSMutableString alloc]initWithFormat:@"tel:%@“,@“114”];

        UIAlertController *alertController = [UIAlertController alertControllerWithTitle:nil message:tel preferredStyle:UIAlertControllerStyleAlert];

        UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:@"取消

        }];

        UIAlertAction *otherAction = [UIAlertAction actionWithTitle:@"呼叫" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {

            [[UIApplication sharedApplication] openURL:[NSURL URLWithString:str]];

        }];

        // Add the actions.

        [alertController addAction:cancelAction];

        [alertController addAction:otherAction];

        [self presentViewController:alertController animated:YES completion:nil];
