程序內調用系統發短信
<pre>

import <messageui messageui.h=""></messageui>

實現代理方法MFMessageComposeViewControllerDelegate

-(void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result
{
[self dismissViewControllerAnimated:YES completion:nil];
switch (result) {
case MessageComposeResultSent:
//信息傳送成功

        break;
    case MessageComposeResultFailed:
        //信息傳送失敗


        break;
    case MessageComposeResultCancelled:
        //信息被用戶取消傳送


        break;
    default:
        break;
}

}
</pre>
發送短信
<pre>
-(void)showMessageView:(NSArray *)phones title:(NSString *)title body:(NSString *)body
{
if( [MFMessageComposeViewController canSendText] )
{
MFMessageComposeViewController * controller = [[MFMessageComposeViewController alloc] init];
controller.recipients = phones;
controller.navigationBar.tintColor = [UIColor redColor];
controller.body = body;
controller.messageComposeDelegate = self;
[self presentViewController:controller animated:YES completion:nil];
[[[[controller viewControllers] lastObject] navigationItem] setTitle:title];//修改短信界面標題
}
else
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@提示信息
message:@該設備不支持短信功能
delegate:nil
cancelButtonTitle:@確定
otherButtonTitles:nil, nil];
[alert show];
}
}
參數phones：發短信的手機號碼的數組，數組中是一個即單發,多個即群發。
