问题 I have a messaging cell that has 3 rows of UILabel, 1. Sender Name, 2. Message 3. Sent Time. Initially, I was keeping an offset of 10 between each of the labels. But I realized that I was wasting space in cases where either the message was too small or if the message wrapped over to a new line and had empty space on the right. So I decided to move the label showing sent time up to save some of that space for the case where the message was too small. I constraint the container like this:

问题 I have a scroll view and inside of if couple labels and a tableView. I would like for that tableView to be scrolled by a outer scrollView and not the tableView's scrollView, so what I did is to set constraint for tableView height to be equal to contentSize height.

问题 I am using UITableViewAutomaticDimension to calculate height for my table view cell. It works fine for me. But for some cells, the height returned is 44 rather than dynamically calculating height. But on scrolling up an looking back to the same cell, the height is recalculated perfectly. So I guess I do not have any faulty constraints because, after I scroll and correct all cell heights manually, no constraint breaking warning are shown afterwards. Edit The below given is the screenshot of

问题 After reading Ray Wenderlich guide for "Self-sizing Table View Cells" as well as this question and answers to it, I've decided to ask all of you for a help. Have a programmically created cell: import UIKit class NotesCell: UITableViewCell { lazy private var cellCaption: UILabel = { let label = UILabel() label.translatesAutoresizingMaskIntoConstraints = false label.font = UIFont.systemFont(ofSize: 20, weight: UIFont.Weight.medium) label.numberOfLines = 0 label.lineBreakMode = .byWordWrapping
