[英]How to properly init passed property in subclass of UIView?
I have a subclass of UIView that I would like to pass a property to.我有一个 UIView 的子类,我想将一个属性传递给它。 As much as I've tried, I don't truly understand all elements of initializing.
尽我所能,我并没有真正理解初始化的所有元素。
Here is a simplified version of my code:这是我的代码的简化版本:
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]
}
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.我已经尝试了很多东西,但是我在 UIView 初始化程序和我通常初始化非子类类的方式之间感到困惑。
How do I modify this code to receive the string property, initialize it?如何修改此代码以接收字符串属性并对其进行初始化? Thanks
谢谢
If you want to initialize a UIView
with a custom property you must reconfigure its initializer: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:
class InputWithIncrementView: UIView {
let inputName: String
init(inputName: String) {
self.inputName = inputName
super.init(frame: .zero)
}
required init?(coder aDecoder: NSCoder) {
return nil
}
}
