effective UI styling for iOS app [closed]

Answer 1

You could create your own styles using enums. By placing enums inside the Styles enum you get a nice grouping:

enum Styles {
    enum Labels {
        case Standard
        case LargeText

        func style(label: UILabel) {
            switch self {
            case .Standard:
                label.font = UIFont.systemFontOfSize(12)
            case .LargeText:
                label.font = UIFont.systemFontOfSize(18)
            }
        }
    }

    enum Buttons {
        case RedButton

        func style(button: UIButton) {
            switch self {
            case .RedButton:
                button.setTitleColor(UIColor.redColor(), forState: UIControlState.Normal)
            }
        }
    }
}

Then you can use it like this:

Styles.Labels.Standard.style(yourLabel)

You can also then make extensions for the styles you have setup:

extension UILabel {
    func style(style: Styles.Labels) {
        style.style(self)
    }
}

extension UIButton {
    func style(style: Styles.Buttons) {
        style.style(self)
    }
}

And then use the extensions like this:

yourLabel.style(.Standard)
yourButton.style(.RedButton)
