从Parse创建的日期以前很快 [英] Swift time ago from Parse createdAt date

问题描述

在一个单元格中，我想从Parse服务器中的NSDate显示时间。这是代码，但它不起作用。什么都没有改变，数据没有被解析。

In a cell I want to display the time ago from the NSDate in the Parse server. Here is the code but its not working. Nothing is changing, and the data isn't being parsed.

    if let createdat = (object?["createdAt"] as? String){
            let pastDate = Date(timeIntervalSinceNow: TimeInterval(createdat)!)
            cell.TimeAgo.text = pastDate.timeAgoDisplay()
        }


       extension Date {
          func timeAgoDisplay() -> String {
        let secondsAgo = Int(Date().timeIntervalSince(self))

        let minute = 60
        let hour = 60 * minute
        let day = 24 * hour
        let week = 7 * day

        if secondsAgo < minute {
            return "\(secondsAgo) sec ago"
        } else if secondsAgo < hour {
            return "\(secondsAgo / minute) min ago"
        } else if secondsAgo < day {
            return "\(secondsAgo / hour) hrs ago"
        } else if secondsAgo < week {
            return "\(secondsAgo / day) days ago"
        }

        return "\(secondsAgo / week) weeks ago"
    }
}
