Swift, super.init() Must call a designated initializer of the superclass 'UIView' error
提问by EberronBruce
I am new with Swift. I inherited a project. I saw it running on a device. However, when I checkout the code and it had many errors. I was able to clear out the errors. However, I run into this one that is baffling me. The project uses xib files as well. Here is the code.
我是 Swift 的新手。我继承了一个项目。我看到它在设备上运行。但是，当我检查代码时，它有很多错误。我能够清除错误。然而，我遇到了这个让我莫名其妙的问题。该项目也使用 xib 文件。这是代码。
required init(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
}
override init(frame: CGRect) {
super.init(frame: frame)
}
init(items:NSArray, viewController:AnyObject){
super.init()
//itemsArray = items
itemsArray = items as [AnyObject]
//commonInit(viewController as UIViewController)
commonInit(viewController as! UIViewController)
}
I get the error under the init(items:NSArray, viewController:AnyObject) method/function. The error is pointed at the "super.init()". It states "Must call a designated initializer of the superclass 'UIView' error"
我在 init(items:NSArray, viewController:AnyObject) 方法/函数下收到错误。错误指向“super.init()”。它指出“必须调用超类‘UIView’错误的指定初始值设定项”
I been searching, googling, asking others and nothing has turned up. Can I get help on fixing this error, or at least why this error happens? I would like understand so I can become a better software developer.
我一直在搜索，谷歌搜索，询问其他人，但没有任何结果。我能否获得修复此错误的帮助，或者至少为什么会发生此错误？我想了解，以便我可以成为更好的软件开发人员。
Edit: I would like to thank everyone for their insight and help. I found out the problem is bigger. I did the changes suggested in the super.init(frame: CGRect). I had to change an array property as well which was affecting the init function.
编辑：我要感谢大家的洞察力和帮助。我发现问题更大了。我做了 super.init(frame: CGRect) 中建议的更改。我还必须更改影响 init 函数的数组属性。

As the error message suggests you can only call the designated initializer of the superclass.
由于错误消息表明您只能调用超类的指定初始化程序。
To solve this you need to call : super.init(frame: frame)instead of super.init()
要解决这个问题，您需要调用 :super.init(frame: frame)而不是super.init()

UIView's designated initializers are:
UIView的指定初始值设定项是：
init(frame: CGRect)
init(coder aDecoder: NSCoder)
You're calling super.init()which is an initializer inherited from its superclass NSObject. Use one of those initialisers instead as the compiler is suggesting.
您正在调用super.init()which 是从其超类继承的初始值设定项NSObject。按照编译器的建议使用这些初始化程序之一。
