先介紹一種最簡單的方法：

調用打電話功能

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

調用發短信功能

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

 

上面的發短信的功能是調用系統的界面，下面是實現一種點擊按鍵就直接發送短信，相當於後台發送，能不能上軟件商店，還不能確定。相對建議來說，盡量使用第一種。

首先導入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:YES];

}

群發短信：

- (IBAction)sendSMS {

     

      BOOL canSendSMS = [MFMessageComposeViewControllercanSendText];

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

      if (canSendSMS) {

     

         MFMessageComposeViewController *picker = [[MFMessageComposeViewControlleralloc] init];

         picker.messageComposeDelegate =self;

         picker.navigationBar.tintColor = [UIColorblackColor];

         picker.body = @"test";

         picker.recipients = [NSArrayarrayWithObject:@"10086"];

         [self presentModalViewController:picker animated:YES];

         [picker release];   

      } 

}

給一個人發短信：
從網頁上獲得內容

-(void)displaySMSComposerSheet

{

    MFMessageComposeViewController *picker = [[MFMessageComposeViewControlleralloc] init];

    picker.messageComposeDelegate =self;

    UIWebView *web = nil;

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

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

    picker.body=[NSStringstringWithFormat:@"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];

}

事件綁定發送短信

-(IBAction)showSMSPicker:(id)sender {

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

    if (messageClass != nil) {

        if ([messageClass canSendText]) {

            [self displaySMSComposerSheet];

        }

        else {

//設備沒有短信功能

       }

    }

    else {

// iOS版本過低,iOS4.0以上才支持程序內發送短信

    }

}
