如何正确初始化UIView子类中的传递属性? [英] How to properly init passed property in subclass of UIView?

问题描述

我有一个UIView的子类，我想将该属性传递给它.尽我所能，我并没有真正理解初始化的所有元素.

I have a subclass of UIView that I would like to pass a property to. As much as I've tried, I don't truly understand all elements of initializing.

这是我的代码的简化版本:

Here is a simplified version of my code:

class inputWithIncrementView : UIView, UITextFieldDelegate {
    var inputName : String // This is the property I want to receive and init

override init (frame : CGRect) {
    super.init(frame : frame)
    // [this is where i will use the inputName property passed on initialization] 
}

required init?(coder aDecoder: NSCoder) {
    super.init(coder: aDecoder) 
}
// [other functions and stuff working fine here]
}

我已经尝试了很多方法，但是在UIView初始化程序和通常初始化非子类的方式之间却感到困惑.

I have tried a number of things, but I'm getting confused between the UIView initializer and the way I normally initialize a non-subclassed class.

如何修改此代码以接收字符串属性，并将其初始化?谢谢

How do I modify this code to receive the string property, initialize it? Thanks

推荐答案

如果要使用自定义属性初始化UIView，则必须重新配置其初始化程序:

If you want to initialize a UIView with a custom property you must reconfigure its initializer:

class InputWithIncrementView: UIView {

    var inputName: String?

    init(inputName: String) {

        self.inputName = inputName
        super.init(frame: CGRect.zero)

    }

    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
    }

}
