代码如下:

- (void)callSellerButtonAction:(UIButton *)button

{

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

     NSString *phoneNumber = @"10086";

    [callWebview loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:[NSString stringWithFormat:@"tel:%@",phoneNumber]]]];

[self.view addSubview:callWebview];

}
