          ^        ---->up arrow

      facebook share

      Twitter share

      Tell a friend

           V      ---->down arrow

我使用mailcomposerview“告诉朋友”按钮和“报告”按钮

当我按下“告诉朋友”或“报告”按钮时，它会在关闭后打开mailcomposerview，我无法移动向上和向下箭头......如果我按向上和向下箭头则打开同样的邮件composerview，它也没有打开Facebook分享和推特分享

请帮我解决这个问题

按下箭头时

我的编码

 -(void)arrTapped1:(id)sender
 {
CCMenuItem *item2=(CCMenuItem*)sender;
int k=item2.tag;
    ////CCLOG(@"k tapp=%dhelp=%d",k,helpVal);

    NSLog(@"HelpVal%i",helpVal);
if(k==51)
{
    if(helpVal<3)
    { 
        id action1=[CCMoveBy actionWithDuration:0.3 position:ccp(0,+260)];
        id callfun1=[CCCallFunc actionWithTarget:self selector:@selector(enabled1) ]; 

        [item2 setIsEnabled:YES];
        [(CCSprite*)[self getChildByTag:10] runAction:[CCSequence actions:action1,callfun1,nil]];
        [self performSelector:@selector(downWardsMove)];
            }

}
else //if(k==50)
        {
    if(helpVal>1)
    {  

        id action1=[CCMoveBy actionWithDuration:0.3 position:ccp(0,-260)];

以下是我在我的应用中使用的代码的一部分，它在iOS 4.0 - iOS 6.0中运行良好。看看：

-(void)sendMessageToEmail:(NSString *)message withSubject:(NSString *)subject
{
    if([self _isIOS6andHigher]) {

        NSArray *activities = @[message];
        UIActivityViewController *viewController = [[UIActivityViewController alloc] initWithActivityItems:activities applicationActivities:nil];

        AppController *app = (AppController*) [[UIApplication sharedApplication] delegate];
        [[app navController] presentViewController:viewController animated:YES completion:nil];
        [viewController release];

    } else {

        MFMailComposeViewController* mailController = [[MFMailComposeViewController alloc] init];
        mailController.mailComposeDelegate = self;
        [mailController setSubject:subject];
        [mailController setMessageBody:message isHTML:NO];

        AppController *app = (AppController*) [[UIApplication sharedApplication] delegate];
        [[app navController] presentModalViewController:mailController animated:YES];
        [mailController release];
    }
}

- (void)mailComposeController:(MFMailComposeViewController*)controller
      didFinishWithResult:(MFMailComposeResult)result
                    error:(NSError*)error
{
    [controller dismissModalViewControllerAnimated:YES];

}

您永远不会发布mailComposer：

mailComposer = [[UIViewController alloc] init];

这可能会导致它泄漏并作为视图保持活动状态。这可以解释缺少触摸事件，因为邮件编辑可能仍会拦截触摸。
