我正在网上搜索很长时间。但是没用。请帮助或尝试给出一些想法来实现这一目标。

当取消存档的应用崩溃时,我收到以下消息:

Terminating app due to uncaught exception 'NSInvalidUnarchiveOperationException', reason:
'*** -[NSKeyedUnarchiver decodeObjectForKey:]: cannot decode object of class (_TtCC11ArchiveTest8dogHouse3dog)
for key (NS.objects); the class may be defined in source code or a library that is not linked'


这是什么意思?
任何人都可以帮助吗?

现在,我知道终止是因为其他代码,例如:

如果我尝试:

做得好,买为什么?在viewDidLoad中编写代码还有其他作用吗?哪个方法链接了类?

我有一堂课:

let ModelPath = "Model.plist".cacheDir()

class dogHouse: NSObject , NSCoding{

 var dogs:[Dog]?

required init(coder aDecoder: NSCoder)
{
    dogs = aDecoder.decodeObject(forKey: "dogs") as? [Dog]
    super.init()
}

func encode(with aCoder: NSCoder) {
    if dogs != nil{
        aCoder.encode(dogs, forKey: "dogs")
    }

}

class Dog: NSObject , NSCoding {

    var name : String?

    required init(coder aDecoder: NSCoder)
    {
        name = aDecoder.decodeObject(forKey: "name") as! String?
        super.init()
    }

    func encode(with aCoder: NSCoder) {
        if name != nil{
            aCoder.encode(name, forKey: "name")
        }

    }

    //ArchiveModels
    func saveModel() -> Bool{
     return NSKeyedArchiver.archiveRootObject(self, toFile: ICModelPath)
    }

    //UnArchiveModels
    class func loadArchiver() -> [Dog]?{
      let obj = NSKeyedUnarchiver.unarchiveObject(withFile: ICModelPath)
      if obj != nil {
         print(obj.debugDescription)
         let model = obj as? dogHouse
         return model?.dogs
      }
     return nil
    }

}

最佳答案

也许您错过了init函数中的参数?

required init(coder aDecoder: NSCoder)
{
    dogs = aDecoder.decodeObject(forKey: "dogs") as? [Dog]
    super.init(aDecoder) //HERE
}

关于swift - 存档和取消存档自定义类(具有作为对象数组的属性),总是失败,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/41820500/
