iphone - 如何在 iOS SDK 中为用户准备一条短信

Question

我使用 Apple Dev 站点上的示例代码来学习如何设置预写电子邮件，但是是否有类似的方法来设置预写 SMS 消息？

首先你必须添加框架 MessageUI到您的项目并导入库 "MessageUI/MessageUI.h" .然后遵守协议(protocol) <MFMessageComposeViewControllerDelegate> .

现在发送短信:

- (IBAction) sendSMS:(id)sender
{
    MFMessageComposeViewController *controller = [[MFMessageComposeViewController alloc] init];
    if([MFMessageComposeViewController canSendText])
    {
        controller.body = @"The body of the SMS you want";
        controller.messageComposeDelegate = self;
        [self presentModalViewController:controller animated:YES];
    }
    [controller release];
}

捕捉发送操作的结果:

- (void) messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result
{
    switch(result)
    {
        case MessageComposeResultCancelled: break; //handle cancelled event
        case MessageComposeResultFailed: break; //handle failed event
        case MessageComposeResultSent: break; //handle sent event
    }
    [self dismissModalViewControllerAnimated:YES];
}
