    NSMutableString *str = [[NSMutableString alloc] initWithFormat: @"tel:%@", self.phone];
    static UIWebView *webView = nil;
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{
        webView = [UIWebView new];
    });
    [webView loadRequest:[NSURLRequest requestWithURL: [NSURL URLWithString: str]]];
    [self.view addSubview: webView];

2.发送短信

方法一：

[[UIApplication sharedApplication]openURL:[NSURL URLWithString:@"sms://10000"]];

方法二：

[self showMessageView:[NSArray arrayWithObjects:@"10086", nil] title:@"test" body:@"abc"];

<p class="p1"><span class="s1"><MFMessageComposeViewControllerDelegate>   (MessageUI.framework)</span></p>

#import <MessageUI/MessageUI.h>

-(void)showMessageView:(NSArray *)phones title:(NSString *)title body:(NSString *)body
{
    if([MFMessageComposeViewController canSendText]) {
        MFMessageComposeViewController * controller = [[MFMessageComposeViewController alloc] init];
        controller.recipients = phones;
        controller.navigationBar.tintColor = [UIColor redColor];
        controller.body = body;
        controller.messageComposeDelegate = self;
        [self presentViewController:controller animated:YES completion:nil];
        [[[[controller viewControllers] lastObject] navigationItem] setTitle:title]; //修改短信界面标题
    } else {
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"提示信息"
                                                        message:@"该设备不支持短信功能"

                                              cancelButtonTitle:@"确定"
                                              otherButtonTitles:nil, nil];
        [alert show];
    }
}
#pragma mark - MFMessageComposeViewController
-(void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result
{
    [self dismissViewControllerAnimated:YES completion:nil];
    switch (result) {
        case MessageComposeResultSent:
            //信息传送成功
            
            break;
        case MessageComposeResultFailed:
            //信息传送失败
            
            break;
        case MessageComposeResultCancelled:
            //信息被用户取消传送
            
            break;
        default:
            break;
    }
