Center a view

To make text center label, we use this line

la.textAlignment = NSTextAlignment.Center

To make label center screen, use this

ima.center = CGPoint(x: view.center.x, y:250)

There’s another way, first get screen width

let r = UIScreen.mainScreen().bounds.size.width

If label width 240, declare a variable name margin

let margin = (Int(r) - 240)/2

Use this variable to set label margin.

la = UILabel(frame: CGRect(x: margin, y: 60, width: 240, height: 25))

This way can use to every view when you know it’s width.
