iOS开发中利用MFMessageComposeViewController发送短信

从SDK4.0开始，就可以在程序内使用MFMessageComposeViewController来发送短信了（如果设备支持的话）。

废话少说，代码如下：

self.msgCtrl = [[MFMessageComposeViewController alloc] init];

[self.msgCtrl release];

if (![MFMessageComposeViewController canSendText]) {

UIAlertView *av = [[UIAlertView alloc] initWithTitle:@"设备不支持短信发送" message:nil delegate:nil cancelButtonTitle:@"取消" otherButtonTitles:nil];

[av show];

[av release];

return;

}

[self.msgCtrl setBody:@"短信内容"];

[self.msgCtrl setRecipients:[self.selectedContactPhoneDict allKeys]];

!!!:            self.msgCtrl.messageComposeDelegate = self;

[self presentModalViewController:self.msgCtrl animated:YES];

特别是标注了!!!的这一行，坑爹的delegate名字是messageComposeDelegate，这样才会触发下面的回调：

-(void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result{

switch (result) {

case MessageComposeResultCancelled:

[[TKAlertCenter defaultCenter] postAlertWithMessage:@"已取消短信发送"];

break;

case MessageComposeResultSent:

[[TKAlertCenter defaultCenter] postAlertWithMessage:@"成功发送短信"];

break;

case MessageComposeResultFailed:

[[TKAlertCenter defaultCenter] postAlertWithMessage:@"短信发送失败"];

break;

default:

break;

}

[self dismissModalViewControllerAnimated:YES];

}
