MFMessageComposeViewControllerDelegate
- (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result
{
[controller dismissModalViewControllerAnimated:NO];//关键的一句   不能为YES
switch ( result ) {
case MessageComposeResultCancelled:
        {
//click cancel button
          }
break;
case MessageComposeResultFailed:// send failed
           
break;
case MessageComposeResultSent:
            {
               
//do something
            }
break;
default:
break;
}

}
我们知道可以使用这样的代码在iphone中发送短信：
[[UIApplication sharedApplication] openURL:@"sms:12345678"];
但这样的方式无法指定短信内容。那么我们可以使用MessageUI框架。

首先在程序中导入MessageUI.framework。import头文件：#import "DeviceDetection.h"

然后在代码中使用下面的语句来调用短信发送窗口，并指定号码和短信内容：

MFMessageComposeViewController *controller = [[[MFMessageComposeViewController alloc] init] autorelease];
controller.body = @"zc";
controller.recipients = [NSArray arrayWithObjects:@"106295598", nil];
controller.messageComposeDelegate = self;
[self presentModalViewController:controller animated:YES];

同时实现协议MFMessageComposeViewControllerDelegate，
在协议方法messageComposeViewController:didFinishWithResult:
中解散窗口：
switch (result) {
case MessageComposeResultCancelled:
NSLog(@"Cancelled");
break;
case MessageComposeResultFailed:
[self alert:@"发送短信错误！"];
break;
case MessageComposeResultSent:
break;
default:
break;
}
[self dismissModalViewControllerAnimated:YES];
