ios - "This UIView seems to be the delegate of an NSISVariable it doesn' t 什么都不知道。这是一个内部 UIKit 错误“错误

Question

我正在做一个 opengl 项目。我使用了一些图像(2 个用于 x-y 比例尺)和标签 (8) 在屏幕上显示比例尺。我的第一个 View 是 tableview，我从中转到 openglView。但是每当我从 openglView 返回到 tableView 时，它都会给我这个错误并且应用程序崩溃。

“这个 UIView 似乎是它一无所知的 NSISVariable 的委托(delegate)。这是一个内部 UIKit 错误。”

有什么建议吗？发生这种情况是因为我包含了太多的 UI 元素，除了那些我还使用了一些按钮的图像和标签。我正在对这些图像和标签以及一个按钮应用 affineTransform。

确切的错误是:

“我从中转到 openglView 的表格 View ”- 此语句结合仿射变换的使用表明您没有使用标准导航并尝试移动 View 并同时使用自动布局。

这次崩溃与相反的约束集有关，我猜你正在应用仿射变换，因此弄乱了一些帧。尝试修改约束常量而不是使用任何转换。
