Setting text to fit the size of a UILabel and centre in SWIFT

Question

I'm trying to set text to fit the size of a UILabel and also be centred. I am doing this programmatically. This is what it looks like currently:

As you can see, the text is going off the screen and is also not centred.

This is my code:

let questions = "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Donec ac faucibus tellus."

questionsLabel = UILabel(frame: CGRectMake(10, 10, questionsView.frame.size.width - 20, 80))
questionsLabel.text = questions
questionsLabel.font = UIFont(name: Font.FuturaMedium, size: 25)
questionsLabel.sizeToFit()
questionsLabel.numberOfLines = 0
questionsLabel.textAlignment = NSTextAlignment.Center
questionsView.addSubview(questionsLabel)

What am I doing wrong?

Answer 1

questionsLabel.sizeToFit()

Makes the frame fit the size of the text. What you are looking for is:

questionsLabel.adjustsFontSizeToFitWidth = true

This changes the font size to fit the width of the label. (However, do note that it will only downsize the font.)

questionsLabel.textAlignment = NSTextAlignment.Center

Centers the text within the label.frame. So if you do the above. And make sure the label is centered, and it's width is correct. You shouldn't have to do anything else to center the text.

Swift 3:

questionsLabel.textAlignment = .center
