TimeAgo 总是显示为“Just Now”

【中文标题】TimeAgo 总是显示为“Just Now”

【英文标题】：TimeAgo Always appears as "Just Now"

【发布时间】：2021-02-15 08:07:28

【问题描述】：

我似乎无法理解发生了什么，以及为什么当它应该改变时什么都没有改变

    let date = Date(timeIntervalSince1970: timestamp)
    let timeAgo = timeAgoSince(date)

    print(timeAgo)

print (timeAgo) 总是显示为“Just Now” 关于这个问题我能得到任何帮助吗？

这是我的扩展

public func timeAgoSince(_ date: Date) -> String 

let calendar = Calendar.current
let now = Date()
let unitFlags: NSCalendar.Unit = [.second, .minute, .hour, .day, .weekOfYear, .month, .year]
let components = (calendar as NSCalendar).components(unitFlags, from: date, to: now, options: [])

if let year = components.year, year >= 2 
    return "\(year) years ago"


if let year = components.year, year >= 1 
    return "Last year"


if let month = components.month, month >= 2 
    return "\(month) months ago"


if let month = components.month, month >= 1 
    return "Last month"


if let week = components.weekOfYear, week >= 2 
    return "\(week) weeks ago"


if let week = components.weekOfYear, week >= 1 
    return "Last week"


if let day = components.day, day >= 2 
    return "\(day) days ago"


if let day = components.day, day >= 1 
    return "Yesterday"


if let hour = components.hour, hour >= 2 
    return "\(hour) hours ago"


if let hour = components.hour, hour >= 1 
    return "An hour ago"


if let minute = components.minute, minute >= 2 
    return "\(minute) minutes ago"


if let minute = components.minute, minute >= 1 
    return "A minute ago"


if let second = components.second, second >= 3 
    return "\(second) seconds ago"


return "Just now"

Timestamp 的值为 1604189555939 但 timeago 并没有改变任何帮助？并感谢

【问题讨论】：

假设您的时间戳是过去的，它是自 1970 年以来的 毫秒...

不是打印timeAgo do print(date)，而是立即发现问题。并且不要在 Swift 中使用 NS... 的东西，有原生类型。

谢谢，我试试

【参考方案1】：

您的时间戳以毫秒为单位，而 Date(timeIntervalSince1970: timestamp) 需要几秒钟，因此使用以下代码将解决您的问题：

let date = Date(timeIntervalSince1970: timestamp / 1000)
let timeAgo = timeAgoSince(date)
print(timeAgo)
