iOS 调用系统发短信以及打电话功能

先介绍一种最简单的方法：

调用打电话功能

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

调用发短信功能

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

上面的发短信的功能是调用系统的界面，下面是实现一种点击按键就直接发送短信，相当于后台发送，能不能上软件商店，还不能确定。相对建议来说，尽量使用第一种。

首先导入MFMessageComposeViewControllerDelegate这个代理，实现里面的方法

-(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]; 

}

群发短信：

- (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];   

      } 

}
给一个人发短信：

从网页上获得内容

-(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:@"我在爱折客上看到：%@ 可能对你有用，推荐给你！link：%@",[webstringByEvaluatingJavaScriptFromString:@"document.title"],absUrl];

   [absUrl release];

   [self presentModalViewController:picker animated:YES];

   [picker release];

}

事件绑定发送短信

-(IBAction)showSMSPicker:(id)sender {

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

    if (messageClass != nil) {

        if ([messageClass canSendText]) {

            [self displaySMSComposerSheet];

        }

        else {

//设备没有短信功能

       }

    }

    else {

// iOS版本过低,iOS4.0以上才支持程序内发送短信

    }

}
