Setting font for collection of labels

Question

I have a nameLabel and I can set the font as

 @IBOutlet weak var nameLabel: UILabel!
 nameLabel.font = UIFont(name: "Georgia-bold", size: 18)

Is there a way, I can do same for collection of labels at once,

@IBOutlet weak var collectionNameLabels: [UILabel]!

Answer 1

If you want to change font of all labels which is created from xib or storyboard in your app, you can use

UILabel.appearance().font = UIFont(name: "Georgia-bold", size: 18)

But if you only want to change font of collectionNameLabels , as @Sivajee Battina said, i think you have to use a loop to change font for each label.

for label in self.collectionNameLabels {
    label.font = UIFont(name: "Georgia-bold", size: 18)
}

Answer 2

If you want to change it more than once, it might be useful to create property for that.

var labelFont: UIFont! { didSet { labels.forEach { $0.font = labelFont } } }

and in viewDidLoad or after set the font:

labelFont = UIFont(name: "Georgia-bold", size: 18)

Answer 3

property observer.

@IBOutlet weak var collectionNameLabels: [UILabel]! {

didSet{
  for nameLabel  in collectionNameLabels{
    nameLabel.font = UIFont(name: "Georgia-bold", size: 18)
  }
}

}
