声明UI对象

Question

Curiosity Question: I just was wondering if there is a real different between the following:

let champNameLabel: UILabel!
champNameLabel = UILabel(frame: CGRectMake( 0, 0,  cellSize(champsPerRow),  textHeight))
champNameLabel.center = CGPointMake(textCenterX, textCenterY)
champNameLabel.textAlignment = .Center
champNameLabel.textColor = UIColor.whiteColor()
champNameLabel.font = champNameLabel.font.fontWithSize(fontSize)
contentView.addSubview(champNameLabel)

And,

let champNameLabel = UILabel()
champNameLabel.frame = CGRectMake( 0, 0,  cellSize(champsPerRow),  textHeight)
champNameLabel.center = CGPointMake(textCenterX, textCenterY)
champNameLabel.textAlignment = .Center
champNameLabel.textColor = UIColor.whiteColor()
champNameLabel.font = champNameLabel.font.fontWithSize(fontSize)
contentView.addSubview(champNameLabel)

I have seen it both ways around the web in tutorials and wanted to know if one way was better or not. Thanks for any help in advance.
