如何以编程方式在iPhone上发送短信？

是否有人知道有可能以及如何通过官方的SDK / Cocoa Touch通过iPhone以编程方式发送SMS ？

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]; 
}

XPC是MacOS中进程间通信的系统之一。 此系统层已开发出来，用于基于使用libSystem的plist结构的传输进行进程间通信，并已启动。 实际上，它是一个界面，允许通过交换字典等结构来管理流程。 由于遗传原因，iOS 5也具有此机制。

您可能已经了解了此介绍的意思。 是的，iOS中有一些系统服务，其中包括用于XPC通信的工具。 我想用一个用于发送SMS的守护程序来举例说明该工作。 但是，应该指出的是，此功能在iOS 6中已修复，但与iOS 5.0-5.1.1有关。 无需使用越狱，专用框架和其他非法工具即可对其进行利用。 仅需要目录/ usr / include / xpc / *中的头文件集。

在iOS中发送SMS的元素之一是系统服务com.apple.chatkit，其任务包括生成，管理和发送短文本消息。 为了便于控制，它具有公共可用的通信端口com.apple.chatkit.clientcomposeserver.xpc。 使用XPC子系统，您可以在未经用户批准的情况下生成和发送消息。

好吧，让我们尝试创建一个连接。

xpc_connection_t myConnection;

dispatch_queue_t queue = dispatch_queue_create("com.apple.chatkit.clientcomposeserver.xpc", DISPATCH_QUEUE_CONCURRENT);

myConnection = xpc_connection_create_mach_service("com.apple.chatkit.clientcomposeserver.xpc", queue, XPC_CONNECTION_MACH_SERVICE_PRIVILEGED);

现在，我们将XPC连接myConnection设置为SMS发送服务。 但是，XPC配置可以创建挂起的连接-我们需要采取进一步的步骤来进行激活。

xpc_connection_set_event_handler(myConnection, ^(xpc_object_t event){
xpc_type_t xtype = xpc_get_type(event);
if(XPC_TYPE_ERROR == xtype)
{
NSLog(@"XPC sandbox connection error: %s\n", xpc_dictionary_get_string(event, XPC_ERROR_KEY_DESCRIPTION));
}
// Always set an event handler. More on this later.

NSLog(@"Received a message event!");

});

xpc_connection_resume(myConnection);

连接已激活。 此时此刻，iOS 6将在电话日志中显示一条消息，指示禁止这种通信。 现在，我们需要生成一个类似于xpc_dictionary的字典，其中包含消息发送所需的数据。

NSArray *recipient = [NSArray arrayWithObjects:@"+7 (90*) 000-00-00", nil];

NSData *ser_rec = [NSPropertyListSerialization dataWithPropertyList:recipient format:200 options:0 error:NULL];

xpc_object_t mydict = xpc_dictionary_create(0, 0, 0);
xpc_dictionary_set_int64(mydict, "message-type", 0);
xpc_dictionary_set_data(mydict, "recipients", [ser_rec bytes], [ser_rec length]);
xpc_dictionary_set_string(mydict, "text", "hello from your application!");

所剩无几：将消息发送到XPC端口并确保已传递。

xpc_connection_send_message(myConnection, mydict);
xpc_connection_send_barrier(myConnection, ^{
NSLog(@"The message has been successfully delivered");
});

就这样。 短信已发送。

添加MessageUI.Framework并使用以下代码

#import <MessageUI/MessageUI.h> 

然后：

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

和委托方法-

- (void)messageComposeViewController:(MFMessageComposeViewController *)controller
             didFinishWithResult:(MessageComposeResult)result {
      [self dismissViewControllerAnimated:YES completion:nil];
 }

- (void)sendSMS:(NSString *)bodyOfMessage recipientList:(NSArray *)recipients
{
    UIPasteboard *pasteboard = [UIPasteboard generalPasteboard];
    UIImage *ui =resultimg.image;
    pasteboard.image = ui;
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"sms:"]];
}
