有没有人知道,通过官方SDK / Cocoa Touch,从iPhone发送短信是否可行,以及如何实现?


当前回答

[[UIApplication sharedApplication]openURL:[NSURL URLWithString:@"sms:number"]] 

这将是最好和最简单的方法。

您可以使用sms:[目标电话号码]URL打开sms应用程序,但没有指示如何用文本预填充sms正文。

这是一个教程,它完全是你正在寻找的:MFMessageComposeViewController。

http://blog.mugunthkumar.com/coding/iphone-tutorial-how-to-send-in-app-sms/

从本质上讲:

MFMessageComposeViewController *controller = [[[MFMessageComposeViewController alloc] init] autorelease];
if([MFMessageComposeViewController canSendText])
{
    controller.body = @"SMS message here";
    controller.recipients = [NSArray arrayWithObjects:@"1(234)567-8910", nil];
    controller.messageComposeDelegate = self;
    [self presentModalViewController:controller animated:YES];
}

还有文档的链接。

用这个:

- (void)showSMSPicker
{
    Class messageClass = (NSClassFromString(@"MFMessageComposeViewController"));

    if (messageClass != nil) {          
        // Check whether the current device is configured for sending SMS messages
        if ([messageClass canSendText]) {
           [self displaySMSComposerSheet];
        }   
    }
}

- (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result
{       
    //feedbackMsg.hidden = NO;
    // Notifies users about errors associated with the interface
    switch (result)
    {
        case MessageComposeResultCancelled:
        {   
            UIAlertView *alert1 = [[UIAlertView alloc] initWithTitle:@"Message" message:@"SMS sending canceled!!!" delegate:self cancelButtonTitle:nil otherButtonTitles:@"OK", nil];
            [alert1 show];
            [alert1 release];
        }   

        // feedbackMsg.text = @"Result: SMS sending canceled";
        break;

        case MessageComposeResultSent:
        {
            UIAlertView *alert2 = [[UIAlertView alloc] initWithTitle:@"Message" message:@"SMS sent!!!" delegate:self cancelButtonTitle:nil otherButtonTitles:@"OK", nil];
            [alert2 show];
            [alert2 release];
        }   

        // feedbackMsg.text = @"Result: SMS sent";
        break;

        case MessageComposeResultFailed:
        {   
            UIAlertView *alert3 = [[UIAlertView alloc] initWithTitle:@"Message" message:@"SMS sending failed!!!" delegate:self cancelButtonTitle:nil otherButtonTitles:@"OK", nil];
            [alert3 show];
            [alert3 release];
        }   

        // feedbackMsg.text = @"Result: SMS sending failed";
        break;

        default:
        {   
            UIAlertView *alert4 = [[UIAlertView alloc] initWithTitle:@"Message" message:@"SMS not sent!!!" delegate:self cancelButtonTitle:nil otherButtonTitles:@"OK", nil];
            [alert4 show];
            [alert4 release];
        }   

        // feedbackMsg.text = @"Result: SMS not sent";
        break;
    }

    [self dismissModalViewControllerAnimated: YES];
}

遵循以下步骤

1 .添加消息i。项目框架

2。在.h文件中导入# Import <MessageUI/MessageUI.h>。

3.复制此代码以发送消息

 if ([MFMessageComposeViewController canSendText]) {
    MFMessageComposeViewController *messageComposer =
    [[MFMessageComposeViewController alloc] init];
    NSString *message = @"Message!!!";
    [messageComposer setBody:message];
    messageComposer.messageComposeDelegate = self;
    [self presentViewController:messageComposer animated:YES completion:nil];
}

4所示。实现委托方法,如果你想。

- (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result{


   ///your stuff here 

    [self dismissViewControllerAnimated:YES completion:nil];
}

快跑!

iOS 4中有一个类支持从应用程序中发送带有正文和收件人的消息。它的工作原理与发送邮件相同。你可以在这里找到文档:链接文本
