相关疑难解决方法(0)

我上课了

class Player {

    var name = ""

    func encodeWithCoder(encoder: NSCoder) {
        encoder.encodeObject(name)
    }

    func initWithCoder(decoder: NSCoder) -> Player {
        self.name = decoder.decodeObjectForKey("name") as String
        return self
    }

    init(coder aDecoder: NSCoder!) {
        self.name = aDecoder.decodeObjectForKey("name") as String
    }

    init(name: String) {
        self.name = name
    }
}

我想序列化并保存到用户默认值.

首先,我不确定如何正确编写编码器和解码器.所以对于init我写了两个方法.

当我尝试执行此代码时:

func saveUserData() {
    let player1 = Player(name: "player1")
    let myEncodedObject = NSKeyedArchiver.archivedDataWithRootObject(player1)
    NSUserDefaults.standardUserDefaults().setObject(myEncodedObject, forKey: "player")
}

应用程序崩溃,我收到此消息:
