更改键盘的字体

Question

我正在使用Swift 2中的自定义键盘。我会为所有标签，按钮和文本使用不同的字体。是否可以为所有代码设置一次字体值？ 我正在努力 `class KeyboardViewController：UIInputViewController {

}`

感谢。

Answer 1

我为之前的回答道歉，试试这个：

override func viewDidLoad() {
    super.viewDidLoad()

    self.setFontFamily("FagoOfficeSans-Regular", forView: self.view!, andSubViews: true)
}




func setFontFamily(fontFamily: String, forView view: UIView, andSubViews isSubViews: Bool) {

    if view.isKindOfClass(UILabel){
        let lbl: UILabel = view as! UILabel
        lbl.font = UIFont(name: fontFamily, size: lbl.font.pointSize)
    }
    if view.isKindOfClass(UIButton){
        let lbl: UIButton = view as! UIButton
        lbl.titleLabel?.font = UIFont(name: fontFamily, size: 12)!
    }

    if view.isKindOfClass(UITextField){
        let lbl: UITextField = view as! UITextField
        lbl.font = UIFont(name: fontFamily, size: 12)

    }

    if isSubViews {
        for sview: UIView in view.subviews {
            self.setFontFamily(fontFamily, forView: sview, andSubViews: true)
        }
    }
}
