CGSize sizeWithAttributes in Swift
what I did is something like this:
swift 5.x
let myString = "Some text is just here..."
let size: CGSize = myString.size(withAttributes: [.font: UIFont.systemFont(ofSize: 14)])
swift 4.x
let myString = "Some text is just here..."
let size: CGSize = myString.size(withAttributes: [NSAttributedStringKey.font: UIFont.systemFont(ofSize: 14)])
swift 3
var originalString: String = "Some text is just here..."
let myString: NSString = originalString as NSString
let size: CGSize = myString.size(attributes: [NSFontAttributeName: UIFont.systemFont(ofSize: 14.0)])
swift 2.x
var originalString: String = "Some text is just here..."
let myString: NSString = originalString as NSString
let size: CGSize = myString.sizeWithAttributes([NSFontAttributeName: UIFont.systemFontOfSize(14.0)])
Just use explicit casting:
var stringsize = (strLocalTelefone as NSString).sizeWithAtt...
Otherwise you can bridge it too:
Bridging is no longer supported in later versions of Swift.
var strLocalTelefone = "some string"
var stringsize = strLocalTelefone.bridgeToObjectiveC().sizeWithAttributes([NSFontAttributeName:UIFont.systemFontOfSize(14.0)])
This answer is worth at least looking at, as it highlights potential differences between the two approaches.
Just one line solution:
yourLabel.intrinsicContentSize.width
for Objective-C / Swift
This will work even your label text have custom text spacing.
