ios - 应用程序在负载终止时崩溃，并出现 NSException 类型的未捕获异常

Question

我今晚一直在玩我的一个项目，现在我无法加载它。奇怪的是我有一个旧版本，甚至试图复制所有数据，但仍然没有加载。

我在 NSLog 中得到的错误如下:

非常感谢任何帮助。

Answer 1

您的 StoryBoard 或 XIB 文件中有一个名为“animate”的幻像连接。

1. 打开您的 Storyboard/XIB 文件
2. 如果您使用的是 StoryBoard，请选择 AdultGame View Controller
3. 点击左侧的“文件所有者”
4. 选择“查看 > 实用程序 > 显示连接检查器”
5. 您将看到“Outlets”列表。其中之一将被称为“动画”，旁边有一个感叹号。单击小“x”将其删除。
