在IOS 6模拟器上没有调用PrepareForSegue

Question

我有一个使用storyboard的应用程序。当我开发它时，它针对的是ios 5，一切都运行良好。但是，当我尝试在ios 6模拟器中运行它时，我发现无法调用“PrepareForSegue”方法。（在这种情况下，我的项目的开发目标仍然针对ios 5）。

这是我在下面的prepareForSegue代码：

-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{

    if ([[segue identifier] isEqualToString:@"sToHowManyTimesView"])
    {

        NSString *title=[relationshipStatus titleForState:UIControlStateNormal];
        NHCThirdViewController *thirdView=[segue destinationViewController];

        thirdView.infoRequest=title;
        relationShipStatus.relstatus=title;

        NSLog(@"%@",title);

    }
    else if([[segue identifier] isEqualToString:@"SinglePage"])
    {
        NSString *title=[relationshipStatus titleForState:UIControlStateNormal];
        relationShipStatus.relstatus=title;

    }
    else if([[segue identifier] isEqualToString:@"toFifthView"])
    {
        NSString *title=[relationshipStatus titleForState:UIControlStateNormal];
        NHCFifithViewController *fifthView=[segue destinationViewController];

        fifthView.infoRequest=title;
        relationShipStatus.relstatus=title;
    }
}

请帮帮我。
