iOS 发短信

1. 导入库：

MessageUI.framework

2. 声明代理类：

MFMessageComposeViewControllerDelegate

3. 功能函数的实现：

比如：

MFMessageComposeViewController *picker = [[MFMessageComposeViewController alloc] init];

picker.messageComposeDelegate = self;

picker.navigationBar.tintColor = [UIColor blackColor];

picker.body = @””;

picker.recipients = [NSArray arrayWithArray:phoneArr];

[self presentViewController:picker animated:YES completion:nil];

4. 必须实现的代理函数：

– (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result

{

[self dismissViewControllerAnimated:YES completion:nil];

}
