Adding UILabel programmatically only by code. Sizing ? (Swift)

Question

I try to add a UILabel by code which works, but not as intended.

With following Code I can see the label but the height of the label is not correct as you can see in the attached screen. I would like the uilabel sized so the height of the label corresponde to the fontsize.

Of course I could simply oversize the UILabels high so the text would fit. But I don't think thats best practice.

How do I size an UILabel based on a fontsize ?

var uilabel1=UILabel();
uilabel1.frame=CGRectMake(0, drawy, screenwidth, ititlesize);
uilabel1.text=sTextViewOptionsTitle;
uilabel1.font = UIFont(name: uilabel1.font.fontName, size: 28);
self.view.addSubview(uilabel1);
var lastelementheigth=uilabel1.frame.height;

UPDATE Solution with sizeToFit()

Thanks for the answer regarding sizeToFit(). This did the trick with some additional code to position the control. updated Code:

  var uilabel2=UILabel();
    //uilabel2.frame=CGRectMake(0, drawy, screenwidth/2, DropdownHeigth);
    uilabel2.text=sTextSizeTextViewer;
    uilabel2.font = UIFont(name: uilabel2.font.fontName, size: iFontsize_Option);
    uilabel2.sizeToFit();
    uilabel2.frame.origin = CGPoint(x: 0, y: drawy);

    self.view.addSubview(uilabel2);
    lastelementheigth=uilabel2.frame.height;

Thanks a lot that did the trick ! I updated my question with updated code. — mcfly soft, Jul 23 '15 at 06:15

You may only need to call -sizeToFit. This will change the label's size to its "preferred" size based on its contents. Then you can reposition the origin or center if desired.

But howto change the origins without setting the frame ? – mcfly soft Jul 23 '15 at 06:17
In Swift, you can say `label.frame.origin = CGPoint(...)`. Or you can use `label.center = CGPoint(...)` – jtbandes Jul 23 '15 at 06:17
Thanks thats even much better. I will update the code for others. – mcfly soft Jul 23 '15 at 06:20

It's been asked before - take a look at: Replacement for deprecated sizeWithFont: in iOS 7?

The method you're looking for is sizeWithAttributes
