我有一个问题，我有几个视图控制器。一个叫PSACurrentGame，另一个叫PSAEnterScores。PSACurrentGame是 的父类PSAEnterScores。我正在尝试将标签PSACurrentGame从PSAEnterScores. 但我已经用父类的东西弄清楚了。真正的问题是，虽然我有与变量链接的正确属性，但变量的文本不会改变。我确认 lanbel 响应viewDidLoad方法的更改，但它不会响应它在子类中的更改。有谁知道为什么？

下面的代码：

PSACurrentGame.h：

@interface PSACurrentGame : UIViewController

如果您需要更多内容，请发表评论，我会添加。

编辑：我改变了顶部的文字，但我也会把它放在这里。标签现在响应其自己类中的更改，但现在是子类中的更改。子类是否只有只读权限才能访问父类变量？

我认为你有两点可以改进：

1）使用 IBOutletCollection 而不是为每个界面控件创建一个；

2) 使用共享数据源并在其值更改时得到通知。然后你可以在你的控件中进行更改，在它们自己的 ViewControllers 中，像这样：

self.dataStore addObserver:self forKeyPath:@"gameScore" options:0 context:nil];

//...

- (void)observeValueForKeyPath:(NSString *)keyPath
                  ofObject:(id)object
                    change:(NSDictionary *)change
                   context:(void *)context {

    if ([keyPath isEqual:@"gameScore"]) {
        //update your IBOutletCollections...
    }
}

我在我的应用程序中使用了这个示例来在视图控制器之间传输数据。因此，它可能会有所帮助：http: //iphonedevsdk.com/forum/iphone-sdk-development/54859-sharing-data-between-view-controllers-and-other-objects-link-fixed.html
