  • iOS中调用系统打电话

    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 = [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];   

          } 

    }

    给一个人发短信:
    从网页上获得内容

    -(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

        }

    }
