I have a cell that has a variable height label for the first line. I found that using automatic dimension some of the cells are sized incorrectly causing this label to be truncated. If I reloadData in viewDidAppear, the size becomes correct.

Steps to Reproduce:
1) Look at the two screen shots provided
2) Notice that in one the bold label shows the ...

The screen shot with the earlier time stamp is without the workaround, the one with the later time stamps has the reloadData as discussed.

Expected Results:
There should always be all lines visible of the text on the bold label

Actual Results:
Some cells (even off screen) get an incorrect size. Only if you reload the cells AFTER the view has appeared on screen the size becomes correct.

iOS 8.4
