swift4：我场景中的 none 个文本字段是可编辑的
swift4: none of textfields in my scene are editable
我的故事板中有一个场景，其所有字段在应用程序 运行 期间均不可编辑。
注意。 我检查了所有文本字段及其所有父字段 userInteractionEnabled 是 true 并且由于这个问题 (My TextField is not editable) 但它没有帮助。我还有其他这样的场景，无需使用任何委托或类似的东西就可以工作，并且它们的文本字段仍然可以编辑。
我确实注释掉了它相关的视图控制器中的所有内容，但是它并没有改变这种情况。
我把它的 XML 代码放在这里供你参考，你可能会找到任何导致这种情况的东西。
我对我的场景所做的更改是：将所有项目放在 StackView 内的嵌套视图中，如果它有一些约束 + 从 Swift3 迁移到 Swift4。

我已将您的故事板粘贴到我的测试项目中并尝试调试此问题。发现当移除ScrollView和StackView之间的视图（下图红色高亮部分），直接将StackView放在Container ScrollView里面时，textFields 变得可点击。
您给出的故事板：
删除 Container Scroll 视图中的视图并将 StackView 直接移动到 Container ScrollView 下后。
移除中间视图后的模拟器截图
我的故事板中有一个场景，其所有字段在应用程序 运行 期间均不可编辑。
注意。 我检查了所有文本字段及其所有父字段 userInteractionEnabled 是 true 并且由于这个问题 (My TextField is not editable) 但它没有帮助。我还有其他这样的场景，无需使用任何委托或类似的东西就可以工作，并且它们的文本字段仍然可以编辑。

我已将您的故事板粘贴到我的测试项目中并尝试调试此问题。发现当移除ScrollView和StackView之间的视图（下图红色高亮部分），直接将StackView放在Container ScrollView里面时，textFields 变得可点击。
您给出的故事板：
删除 Container Scroll 视图中的视图并将 StackView 直接移动到 Container ScrollView 下后。
移除中间视图后的模拟器截图
