问题描述
我看过几个类似我的问题;然而,这些都是关于快速2/1,我目前正在使用swift 3.我相信苹果已经稍微改变了。 class Person:NSObject,NSCoding { var signature:UIImage init(signature:UIImage){ self.signature = signature } 需要方便的init(coder aDecoder:NSCoder){ let signature = aDecoder.decodeObject(forKey:signature)as! UIImage self.init(签名:签名)} func encodeWithCoder(aCoder:NSCoder){ aCoder.encode(signature,forKey:signature) } }
你会注意到Swift 3如何迫使我使用所需的便利性init(而不是必需的init(或许这与它有关系) / p>
如何解决这个问题?谢谢!
解决方案code> encode 在Swift 3中的方法已被重命名为
func encode(with aCoder :NSCoder)当您获得不符合错误时,您可以轻松地找出哪些需要的方法缺少

I have seen several questions similar to mine; however, those are pertaining to swift 2/1 and I am currently using swift 3. I believe Apple has changed it slightly.
class Person: NSObject, NSCoding { var signature: UIImage init(signature: UIImage) { self.signature = signature } required convenience init(coder aDecoder: NSCoder) { let signature = aDecoder.decodeObject(forKey: "signature") as! UIImage self.init(signature: signature) } func encodeWithCoder(aCoder: NSCoder) { aCoder.encode(signature, forKey: "signature") } }You will notice how Swift 3 now forces me to use required convenience init( instead of required init(. Perhaps that has something to do with it.
How can I resolve this issue? Thanks!
解决方案The encode method in Swift 3 has been renamed to
func encode(with aCoder: NSCoder)When you get the do not conform error you can easily find out which required methods are missing
