为什么 IQKeyboardManager 不滚动我的 UITableView 以使我的自定义单元格的文本字段可见
Why doesn't IQKeyboardManager scroll my UITableView to make my custom cell's textfield visible
这是我目前得到的结果（不需要的）：https://vimeo.com/459984986.
这是我使用变通方法得到的结果（几乎是我想要的）：https://vimeo.com/459986233.
关于我的问题的总结如下：(1)我已经安装了“IQKeyboardManagerSwift”cocoapod，(2) 我的 UITableViewController 中有一个自定义单元格，它是一个 FolingCell（另一个 cocoapod）并且包含一个文本字段，当我点击内部时 (3)文本字段，我希望视图自动向上滚动以使文本字段可见（在键盘上方），这应该由 IQKeyboardManager 自动处理（是的，我添加了“启用" 我的 AppDelegate 中的代码）。
如上面“不需要的”结果视频所示，视图似乎试图滚动但最终只是上下抖动 在键盘向上滑动并不希望地覆盖文本字段时，稍微结束在原始位置之前。
此外，我发现我不想接受的小“解决方法”是将以下行添加到文本字段的 IBAction editingDidEnd outlet/action 函数中：“ sender.becomeFirstResponder()”。在我 iPhone 上更新到 XCode 12 和 iOS 14 之前，我 运行 并测试我的应用程序，我不必为“.becomeFirstResponder()”操心或“.resignResponder()”，因为那是 IQKeyboardManager 自动执行的操作。现在，添加上述代码行允许 UITableViewController 将视图移动到键盘上方。 但是， 如果你仔细观察，它位于键盘顶部的文本字段，这显然不是 IQKeyboardManager 因为 IQKeyboardManager 在文本字段和键盘之间的默认偏移量为 CGFloat(10)。
我认为 代码的相关部分 是我的 自定义单元格 （称为“SavedImageFoldingImageCell”），因为那是我创建文本字段的地方有问题和我的 UITableViewController（称为“SavedImageTableViewController”）。
拜托，你能提供的任何帮助、建议和忠告都会对我有很大帮助，我将不胜感激。谢谢！
是的，我的代码看起来很糟糕，因为我没有适当的 training/education 编码或一般编码的最佳实践。那里的建议也将不胜感激！如果您发现我可以缩短和组织代码的方法，请务必泄露您的秘密！

我通过简单地将 class 从 UITableViewController -> UIViewController 切换来解决我自己的问题。我在 IQKeyboardManager 的 Github 页面上浏览了已关闭的问题，发现由于 Apple 的 UITableViewController 自动处理视图和键盘的移动，IQKeyboardManager 的 开发人员选择忽略 UITableViewController 中的文本字段。因此，您必须将 class 更改为 UIViewController 或另一个受支持的 class 才能让 IQKeyboardManager.
