我有这个简单的课程
import UIKit
class SimpleModel: NSObject, NSCoding {
var name : String!
var done : Bool!
init(name:String) {
self.name = name
self.done = false
}
internal required init?(coder aDecoder: NSCoder) {
self.name = aDecoder.decodeObject(forKey: "name") as! String
self.done = aDecoder.decodeBool(forKey: "done") // BUG HERE
}
func encode(with encoder: NSCoder) {
encoder.encode(self.name, forKey: "name")
encoder.encode(self.done, forKey: "done")
}
}
保存代码:
let data = NSKeyedArchiver.archivedData(withRootObject: storageArray)
UserDefaults.standard.set(data, forKey: "storage")
UserDefaults.standard.synchronize()
读取代码:
if let data = UserDefaults.standard.data(forKey: "storage") {
storageArray = NSKeyedUnarchiver.unarchiveObject(with: data) as! [SimpleModel]
}
当 NSKeyedUnarchiver 完成它的工作时,就会出现问题。我不明白问题出在哪里。
谢谢!
