Dynamic UITableViewCell not resizing according to the content

Question

Senario A: If I set the label content in cellForRowAtIndexPath, the cell correctly get resized.

Senario B: If I change the text content in custom action in cell, the cell sized does not get changed.(I do call setNeedsLayout + layoutIfNeeded)

How to fix this?

EDIT:

1) I have set, myTableView.estimatedRowHeight = 71.0 myTableView.rowHeight = UITableViewAutomaticDimension

2) I have correctly added auto layout constraints.

Answer 1

I was running into this issue, and my problem was that I was constraining the content to self (the UITableViewCell) and not to self.contentView (the contentView OF the cell). Hope this helps someone else who has built their cells all in code!

Answer 2

In my case, the cell's custom size was enabled:

Answer 3

After you change the text of the cell, just reload that particular cell or simply call mainTableView.reloadData().

To reload that cell-

//indexPath is indexPath of cell you just changed label of
mainTableView.reloadRows(at: indexPath, with: .automatic)

Answer 4

In my case, in the same cell I had an imageView in the top left corner with a "center vertically in container" constraint, and a "top space container" constraint.

Obviously to satisfy this two constraint the cell must have an height equal to:

(height of the imageView / 2) + (length of the top space container constraint).

This height is not enough to fit the label text, so my label had only 1 line visible.

After I have deleted the imageView top constraint all went to the right place, in my case i wanted the image to be centered, if the image had to stay in the top left corner I had to take off the "center vertically in container" constraint.

I hope this can help someone.
