iPhone 6上的UICollectionViewCell高度增加不正确

标签： ios uicollectionviewcell

我正在使用UICollectionView并使用自定义UICollectionViewCell。用户创建的帖子显示在“新闻Feed”屏幕上。根据文本的长度，我增加了单元格的高度。但是在“Say Something”文本字段下会出现奇怪的间距。

当用户按ENTER键输入文字时，它的效果非常好。如果用户在没有按ENTER的情况下输入多行，则会出现问题。

此代码适用于iPhone 5，但不适用于iPhone 6和6 plus。自上个星期以来，我一直坚持这个问题。此问题是否仅与iPhone 6和6相关？

我没有找到关于我的问题的相关问题，这就是为什么要问一个新问题。
