I have a UILabel that displays some chars. Like "x", "y" or "rpm". How can I calculate the width of the text in the label (it does not ues the whole available space)? This is for automatic layouting, where another view will have a bigger frame rectangle if that UILabel has a smaller text inside. Are there methods to calculate that width of the text when a UIFont and font size is specified? There's also no line-break and just one single line.
Since sizeWithFont
is deprecated, I'm just going to update my original answer to using Swift 4 and .size
//: Playground - noun: a place where people can play
import UIKit
if let font = UIFont(name: "Helvetica", size: 24) {
let fontAttributes = [NSAttributedStringKey.font: font]
let myText = "Your Text Here"
let size = (myText as NSString).size(withAttributes: fontAttributes)
}
The size should be the onscreen size of "Your Text Here" in points.
