我正在尝试将 plist 数据加载到具有两个视图的实用程序模板应用程序中的 UILabels 中。有一个翻转动画允许在视图之间切换。

这是plist的结构：

Root...............................(Array)
........Item 0.....................(Dictionary)
.................Question..........(string)  ///Hello////
.................Answer............(string) ///Goodbye//

我已经设法使用键（Constants.h）将问题字符串加载到第一个视图（FlashCard1ViewController）中，但我正在努力让答案字符串加载到第二个视图（FlippedView）中。有人能帮忙吗？

以下是我正在使用的代码，如果有人有其他问题或需要澄清，请告诉我，我会尽力回答。

感谢
