问题描述
我正在尝试展示我在xib文件中内置的自定义键盘,当我实例化该类时,我需要将一些变量传递给该类,以使事情正常运行,但是却出现了此错误:
Instance member 'target' cannot be used on type 'CustomKeyboardView'
在线
self.target = target
self.section = section
class CustomKeyboardView: UIView {
weak var target:UIKeyInput?
var section:Int?
class func instanceFromNib(target: UIKeyInput,section: Int) -> UIView {
self.target = target
self.section = section
return UINib(nibName: "CustomKeyboard",bundle: nil).instantiate(withOwner: nil,options: nil)[0] as! UIView
}
}
如何解决此问题或以其他方式将信息传递给班级?
解决方法
您尝试将值设置为类类型而不是实例。首先从笔尖获取键盘,然后设置其属性并返回:
class func instanceFromNib(target : UIKeyInput,section : Int) -> UIView {
let keyboard = UINib(nibName: ...
keyboard,target = target
keyboard.section = section
return keyboard
}
