我的情况是我有一个collectionView，其中包含两种类型的单元格。第一种单元格类型是简单的可编辑UITextField，第二种单元格包含一个UITableView，其单元格内部具有可编辑的UITextFields。
我的问题是，由于表视图单元格内的文本字段而导致键盘出现并且我更改了$ xcrun usdz_converter ~/Desktop/obj_file/demo.obj ~/Desktop/obj_file/demo.usdz -v -a -l

Version: 1.008
-v: Verbose output
-a: Generate .usda intermediate file
-l: Leave generated .usda file
时，更改没有发生。
这是我用来更改键盘出现时的插入的代码，并且与选择“收集视图”单元格中的文本字段时的代码相同（有效）。
contentInset肯定有一些我无法想到的事情阻止了contentInsets的改变。
我也有一个自定义self.view.setNeedsLayout()
self.collectionView.contentInset.bottom = inset
self.view.layoutIfNeeded()
，尽管我认为这无关紧要，因为那只与collectionView的内容有关，而与插图无关。
任何帮助将不胜感激。
答案 0 :(得分：0)
证明它起作用的原因是因为其中包含textview的单元格正在进行一些神奇的自动滚动，而具有tableview textview的单元格却没有进行自动滚动，我猜测是因为它已经嵌套在视图堆栈中处理这个。
我的解决方法是调整contentOffset以强制滚动。
