Swift UITableView 无法正确计算内容高度

Question

I'm having this weird issue with UITableView that can't calculate it's content's height properly.

I have custom UITableView class that is embedded in another custom UITableView, I want it to auto-adjust it's height to fit content so I have already:

override var contentSize: CGSize {
    didSet {
        self.invalidateIntrinsicContentSize()
    }
}

override var intrinsicContentSize: CGSize {
    self.layoutIfNeeded()
    return self.contentSize
}

And now when I use:

self.estimatedRowHeight = UITableView.automaticDimension // non-zero value like 40 isn't working either
self.rowHeight = UITableView.automaticDimension

the output is the frame that is not full height, when I turn "Scrolling enabled" in this TableView it's scrollable with full content (don't want that):

Now when I change

self.estimatedRowHeight = UITableView.automaticDimension

to:

self.estimatedRowHeight = 0

the output is exactly what I would want to have except the content text is cut...

Here's my CommentCell:

Console isn't showing any errors with autolayout in any case.

Do you maybe know what's going on? I have spent literally days trying to get those comments to work and that's the last thing I need. If you need any more info please just tell me.

Edit: If i change estimatedRowHeight to a large number for example 500 I get loads of empty space under cells: So it looks like TableView can't fix the cell height to content. Maybe this will help someone.

Answer 1

Maybe it's about the textfield inside the CellView. Did you set it's Layout to wraps?

Also I would try to set it's intrinsic size value to 'placeholder' inside the Size Inspector.
