发送短信 iPhone

我试图从我的应用程序内发送短信。我写了这段代码，但似乎不起作用。没有崩溃，没有错误日志，什么也没有发生（当然我尝试记录canSendText，结果是1）。

- (void)viewDidLoad
{
    [super viewDidLoad];

    messageComposer = [[MFMessageComposeViewController alloc] init];

    if ([MFMessageComposeViewController canSendText]) {

        [messageComposer setBody:@"Messaggio generato da SMSTest"];
        [messageComposer setRecipients:[NSArray arrayWithObject:@"3333333333"]];
        [messageComposer setDelegate:self];

        [self presentModalViewController:messageComposer animated:YES];
    }
}

谁能解释一下我做错了什么？

I was trying to send SMS from within my app. I wrote this piece of code but it seems not to work.
No crash, no error log, simply nothing happen (of course I tried to log canSendText and the result is 1).

- (void)viewDidLoad
{
    [super viewDidLoad];

    messageComposer = [[MFMessageComposeViewController alloc] init];

    if ([MFMessageComposeViewController canSendText]) {

        [messageComposer setBody:@"Messaggio generato da SMSTest"];
        [messageComposer setRecipients:[NSArray arrayWithObject:@"3333333333"]];
        [messageComposer setDelegate:self];

        [self presentModalViewController:messageComposer animated:YES];
    }
}

Can anyone explain me what I'm doing wrong?

问题是 presentModalViewController 无法在 viewDidLoad 中工作，因为视图已加载，但可能还没有出现在屏幕上。如果您将代码放入 viewWillAppear:animated 中，这应该可以工作。

编辑：根据 Saphrosit 的评论：viewDidAppear: 是一个更好的地方。

我成功地使用了它：

MFMessageComposeViewController *controller = [[MFMessageComposeViewController alloc] init];
controller.messageComposeDelegate = self;
controller.modalPresentationStyle = UIModalPresentationFullScreen;
[self presentModalViewController:controller animated:YES];

请注意，它是 messageComposeDelegate，而不是像您那样的“委托”。

I use this successfully:

MFMessageComposeViewController *controller = [[MFMessageComposeViewController alloc] init];
controller.messageComposeDelegate = self;
controller.modalPresentationStyle = UIModalPresentationFullScreen;
[self presentModalViewController:controller animated:YES];

Note that it's messageComposeDelegate, not 'delegate' as you do.

当我在模拟器上尝试代码时，我收到一个 UIAlert 消息，说短信不可用，因为模拟器无法发送消息。您是否检查过您的头文件是 MFMessageComposeViewControllerDelegate 的委托？

YourClassName : UIViewController  <MFMessageComposeViewControllerDelegate>

When i try the code on simulator i get an UIAlert saying text messaging is not available, because simulator can´t send messages. Have you checked that your header file is a delegate of MFMessageComposeViewControllerDelegate ?

YourClassName : UIViewController  <MFMessageComposeViewControllerDelegate>

//试试这个...它将运行..

MFMessageComposeViewController *controller = [[[MFMessageComposeViewController alloc] init] autorelease];
      if([MFMessageComposeViewController canSendText])
      {
          controller.body = @"来自卡蒂克的你好";
          controller.recipients = [NSArray arrayWithObjects:@"12356478", nil];
          控制器.messageComposeDelegate = self;
          [自我呈现ModalViewController：控制器动画：是]；
      }

//try this ... it will run ..

MFMessageComposeViewController *controller = [[[MFMessageComposeViewController alloc] init] autorelease];
      if([MFMessageComposeViewController canSendText])
      {
          controller.body = @"Hello from Kartik";
          controller.recipients = [NSArray arrayWithObjects:@"12356478", nil];
          controller.messageComposeDelegate = self;
          [self presentModalViewController:controller animated:YES];
      }
