How to make UILabel resize to fit text

I have a UILabel that I have layed out in a storyboard centred in the view. It has some initial text "tap to login".

I am changing the value of the label to be the user's name once they have logged in. Once I do this, the label is no longer centered as the UILabel has not changed size.

How can I do this with autolayout in interface builder?

1.showing initial text to label 2.After pressing button changing text, that showing in middle of screen 3.Look at constraints third image, two constraints given 1.top to view 2.horizontally middle in container

Another thing if u given fixed width for the label,change relation as more than equal.[Click width constraint ,see right side top there change the relation]

You can set the UILabel frame.width bigger, maybe the same width as the screen.

Then you set the

label.textAlignment = NSTextAlignmentCenter

Iam guessing the label is not getting height and width, consider giving those constraints and then when your text changes use this method to determine the height and width:

    func labelSizeWithString(text: String, maxWidth : CGFloat,numberOfLines : Int) -> CGRect{
    let label = UILabel(frame: CGRectMake(0, 0, maxWidth, CGFloat.max))
    label.numberOfLines = numberOfLines
    label.text = text

    label.sizeToFit()

    return label.frame
}
