swift 序列化和反序列化

swift序列化和反序列化

枚舉和數組的序列化都有示範

• 序列化
• 反序列化

基礎類

enum Style:Int{
  StyleA = 0
  StyleB = 1
}
Class A:NSObject{
  var style:Style?
  var num:Int?
  var str:String?
  var arr:Array?
} 

序列化

• 編碼成ojbect 如下

func encodeWithCoder(aCoder:NSCoder!){
    aCoder.encode(self.style.rawValue,forKey:"style")
    aCoder.encode(self.num,forKey:"num")
    aCoder.encode(self.str,forKey:"str")
    aCoder.encode(self.arr,forKey:"arr")
}

反序列化

init(coder aDecoder:NSCoder!){
    self.style = Style(rawValue: aDecoder.decodeInteger(forKey:"style"))
    self.num = aDecoder.decodeInteger(forKey:"num")
    self.str = aDecoder.decodeObject(forKey:"str")
    self.arr = aDecoder.decodeObject(forKey:"arr")
}
