短信分享怎么实现？自己写的会出现闪退

[xsj635953015]

我的项目是个webView
这是.h：
@interface arcUIWebView : NSObject<UIWebViewDelegate,UIActionSheetDelegate,CLLocationManagerDelegate,UIAlertViewDelegate,MFMessageComposeViewControllerDelegate> {
@public
UIWebView* aCtl;
...
...
- (void)sendSMS;
- (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result;
---------------------------------
.m:
actionsheet方法中：
}else if(buttonIndex==2){
//短信分享
[self sendSMS];
}
//短信内容
- (void)sendSMS
{
MFMessageComposeViewController *controller = [[MFMessageComposeViewController alloc] init];
if([MFMessageComposeViewController canSendText])
{
controller.body=@"m.ts.gov.cn";
controller.messageComposeDelegate = self;
[aCtl presentModalViewController:controller animated:YES];
}
}
// 处理发送完的响应结果
- (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result
{
...
}

执行sendMSM就出现闪退了，求帮助

UIWebView 没有这个功能： presentModalViewController： 这个属于UIViewController 的， 而UIWebView 属于 UIView
