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

你可以展示MFMessageComposeViewController,它可以发送短信,但是有用户提示(他点击发送按钮)。没有用户许可,不可能这样做。在iOS 11上,你可以做扩展,就像传入消息的过滤器,告诉iOS它是不是垃圾邮件。没有什么是短信不能做的

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];
}
//Add the Framework in .h file

#import <MessageUI/MessageUI.h>
#import <MessageUI/MFMailComposeViewController.h>

//Set the delegate methods

UIViewController<UINavigationControllerDelegate,MFMessageComposeViewControllerDelegate>

//add the below code in .m file


- (void)viewDidAppear:(BOOL)animated{
    [super viewDidAppear:animated];

    MFMessageComposeViewController *controller = 
    [[[MFMessageComposeViewController alloc] init] autorelease];

    if([MFMessageComposeViewController canSendText])
    { 
        NSString *str= @"Hello";
        controller.body = str;
        controller.recipients = [NSArray arrayWithObjects:
                                 @"", nil];
        controller.delegate = self;
        [self presentModalViewController:controller animated:YES];  
    }


}

- (void)messageComposeViewController:
(MFMessageComposeViewController *)controller
                 didFinishWithResult:(MessageComposeResult)result 
{
    switch (result)
    {
        case MessageComposeResultCancelled:  
            NSLog(@"Cancelled");    
            break; 
        case MessageComposeResultFailed:
            NSLog(@"Failed");
            break;   
        case MessageComposeResultSent:      
            break; 
        default:  
            break;  
    }  
    [self dismissModalViewControllerAnimated:YES]; 
}

你可以使用这种方法:

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

iOS会自动从你的应用程序导航到消息应用程序的消息合成页面。由于URL的方案是从sms:开始的,这被标识为消息应用程序可以识别的类型,并启动它。

你可以展示MFMessageComposeViewController,它可以发送短信,但是有用户提示(他点击发送按钮)。没有用户许可,不可能这样做。在iOS 11上,你可以做扩展,就像传入消息的过滤器,告诉iOS它是不是垃圾邮件。没有什么是短信不能做的

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
