我有一个适用于Snow Leopard的PreferencePane，我们正在为Lion做好准备。 PreferencePane无法加载，并在控制台中给我出现以下错误。请注意，它引用了3个NSTextField实例（每NSTextField报告两次相同的错误）。将PreferencePane移植到Lion [NSTextField getCString：maxLength：encoding：]：问题
我偏好窗格中有三个以上的NSTextFields。这发生在initWithBundle之后：成功完成但在mainViewDidLoad之前。

请注意，Lion仍处于保密协议之下。 – 2011-05-12 07:51:55
