Question

我有以下变量来自＆＃34; ScoreHistory.swift＆＃34;：

if ($current_day >= 0 && $current_day <= 4 && $current_time >= 9 && $current_time <= 17 )

我正在尝试将数据显示到＆＃34; ScoreHistoryViewController.swift＆＃34;

// ScoreHistory.swift

var datePlayed: NSDate
var totalScore: Int
var totalAnswered: Int
var totalDuration: Int
var gameStatus: String

但他们都错了：实例成员'____'不能用于'ScoreHistory'类型

这是什么意思？

我的ScoreHistory.swift的完整代码如下所示：

// ScoreHistory.swift

navigationItem.title = ScoreHistory.datePlayed
datePlayedLabel.text = ScoreHistory.datePlayed
totalScoreLabel.text = ScoreHistory.totalScore
totalAnsweredLabel.text = ScoreHistory.totalAnswered
totalDurationLabel.text  = ScoreHistory.totalDuration
gameStatusLabel.text  = ScoreHistory.gameStatus

Answer 1

根据您的模型设计，您无法访问类ScoreHistory.datePlayed

等类的属性

您必须创建一个实例。

let history = ScoreHistory(datePlayed: NSDate(), totalScore: 0, totalAnswered: 0, totalDuration: 0, gameStatus: "started")

并调用属性

navigationItem.title = history.datePlayed

实例成员'____'不能用于'ScoreHistory'类型
