先介紹一種最簡單的方法：

呼叫打電話功能

[[UIApplicationsharedApplication] openURL:[NSURL URLWithString:@"tel://10086"]];

呼叫發簡訊功能

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

上面的發簡訊的功能是呼叫系統的介面，下面是實現一種點選按鍵就直接傳送簡訊，相當於後臺傳送，能不能上軟體商店，還不能確定。相對建議來說，儘量使用第一種。

首先匯入MFMessageComposeViewControllerDelegate這個代理，實現裡面的方法

-(void)messageComposeViewController:(MFMessageComposeViewController *)controllerdidFinishWithResult:(MessageComposeResult)result {

      //Notifies users about errors associated with the interface

      switch (result) {

         case MessageComposeResultCancelled:

            if (DEBUG) NSLog(@"Result: canceled"

            break;

         case MessageComposeResultSent:

            if (DEBUG) NSLog(@"Result: Sent");

            break;

         case MessageComposeResultFailed:

            if (DEBUG) NSLog(@"Result: Failed");

            break;

         default:

            break;

      }

      [self dismissModalViewControllerAnimated

}

群發簡訊：

- (IBAction)sendSMS {

      BOOL canSendSMS = [MFMessageComposeViewController canSendText];

      NSLog(@"can send SMS [%d]",canSendSMS); 

      if (canSendSMS) {

         MFMessageComposeViewController *picker = [[MFMessageComposeViewController alloc] init];

         picker.messageComposeDelegate = self;

         picker.navigationBar.tintColor = [UIColor blackColor];

         picker.body = @"test";

         picker.recipients = [NSArray arrayWithObject:@"10086"];

         [self presentModalViewController:picker animated:YES];

         [picker release];   

      } 

}

從網頁上獲得內容

-(void)displaySMSComposerSheet

{

    MFMessageComposeViewController *picker = [[MFMessageComposeViewController alloc] init];

    picker.messageComposeDelegate = self;

    UIWebView *web = nil;

    NSMutableString* absUrl = [[NSMutableString alloc] initWithString:web.request.URL.absoluteString];

    [absUrl replaceOccurrencesOfString:@"http://i.aizheke.com" withString:@"http://m.aizheke.com" options:NSCaseInsensitiveSearch range:NSMakeRange(0, [absUrl length])];

    picker.body=[NSString stringWithFormat:@"我在愛折客上看到：%@ 可能對你有用，推薦給你！link：%@",[webstringByEvaluatingJavaScriptFromString:@"document.title"],absUrl];

   [absUrl release];

   [self presentModalViewController:picker animated:YES];

   [picker release];

}

事件繫結傳送簡訊

-(IBAction)showSMSPicker:(id)sender {

    Class messageClass = (NSClassFromString(@"MFMessageComposeViewController"));

    if (messageClass != nil) {

        if ([messageClass canSendText]) {

            [self displaySMSComposerSheet];

        }

        else {

//裝置沒有簡訊功能

       }

    }

    else {

// iOS版本過低,iOS4.0以上才支援程式內傳送簡訊

    }

}
