IOS程序内发短信 MFMessageComposeViewController

文章转载地址:http://www.headsky.org/?p=63

iOS4.0新加入了MFMessageComposeViewController和MFMessageComposeViewControllerDelegate,提供了发送短信的接口,可以像发送邮件那样不用跳出程序来发送短信. 介绍可参阅Message UI
Framework Reference

一些笔记:

MFMessageComposeViewController

  • 提供了操作界面
  • 使用前必须检查canSendText方法,若返回NO则不应将这个controller展现出来,而应该提示用户不支持发送短信功能.
  • 界面不能自行定制
  • 要发送的短信的内容(body)和收件人(recipients)在展现这个controller前需初始化好,展现了之后短信内容不能通过程序来进行修改.不过用户仍然可以手工修改短信内容和选择收件人
  • 用户点了发送或者取消,或者发送失败时,MFMessageComposeViewControllerDelegate 的– messageComposeViewController:didFinishWithResult:方法都能得到通知,在这里进行相应的处理

若在iOS3.0上运行的话,会提示dyld: Symbol not found: _OBJC_CLASS_$_MFMessageComposeViewController .解决方案:

    1. MessageUI.framework的引入类型应选择weak(在target -> Get Info -> General -> Linked Libraries -> MessageUI.framework -> Type 里修改)
    2. 不要在.h文件里直接import MessageUI/MFMessageComposeViewController.h,改为import <MessageUI/MessageUI.h>
      #pragma mark -
      #pragma mark SMS
      
      -(IBAction)showSMSPicker:(id)sender {
         //    The MFMessageComposeViewController class is only available in iPhone OS 4.0 or later.
         //    So, we must verify the existence of the above class and log an error message for devices
         //        running earlier versions of the iPhone OS. Set feedbackMsg if device doesn’t support
         //        MFMessageComposeViewController API.
         Class messageClass = (NSClassFromString(@”MFMessageComposeViewController”));
      
         if (messageClass != nil) {
             // Check whether the current device is configured for sending SMS messagesif ([messageClass canSendText]) {
                 [self displaySMSComposerSheet];
             }
             else {
                 [UIAlertView quickAlertWithTitle:@"设备没有短信功能" messageTitle:nil dismissTitle:@"关闭"];
             }
         }
         else {
             [UIAlertView quickAlertWithTitle:@"iOS版本过低,iOS4.0以上才支持程序内发送短信" messageTitle:nil dismissTitle:@"关闭"];

         [absUrl release];
         [self presentModalViewController:picker animated:YES];
         [picker release];
      }
      
      - (void)messageComposeViewController:(MFMessageComposeViewController *)controller
                      didFinishWithResult:(MessageComposeResult)result {
      
         switch (result)

             case MessageComposeResultFailed:
                 [UIAlertView quickAlertWithTitle:@"短信发送失败" messageTitle:nil dismissTitle:@"关闭"];
                 break;
             default:
                 LOG_EXPR(@”Result: SMS not sent”);
                 break;
         }
         [self dismissModalViewControllerAnimated:YES];
