Multiline UILabel with adjustsFontSizeToFitWidth

Question

I have a multiline UILabel whose font size I\'d like to adjust depending on the text length. The whole text should fit into the label\'s frame without truncating it.

Answer 1

Thought I would add my own take on the answer:

I think it's a slight improvement on some of the other answers because:

1. Caching while looping through words to find the longest by width, to prevent unnecessary calculations
2. All the label attributes are used when doing size calculations

Note: This solution should only be used when a UILabel has .numberOfLines = 0 and .lineBreakMode = .byWordWrapping

Otherwise you are better off using: .adjustFontSizeForWidth = true from the standard swift library

The other answers on this thread were very helpful to me in coming up with my solution, thank you
