如何在Objective-C中格式化日期，类似于jquery.timeago库？ [英] How can I format a date in Objective-C similar to the jquery.timeago library?

问题描述

我有一个显示在表格单元格中的项目，其中一部分是过去的日期/时间戳。

I have a feed of items displayed in table cells, part of which is a date / timestamp in the past.

在Objective-C中，我如何以与 jquery.timeago插件？

In Objective-C, how can I accomplish formatting them in the same manner as the jquery.timeago plugin on the web?

即接收日期并输出如下内容：

That is, taking in a date and outputting things like:

• 'just now'


• '2分钟前'


• '24天前'


• '一个月前'

• 'just now'
• '2 minutes ago'
• '24 days ago'
• 'a month ago'

我看到有 NSDate扩展类，其中包含dateWithDaysBeforeNow，dateWithMinutesBeforeNow等方法，但是如果有一个库已经完成了我将使用它。

I see there is an NSDate extension class here with methods such as dateWithDaysBeforeNow, dateWithMinutesBeforeNow, etc, but if there is a library out there that has already done this I will use it.

编辑：除此之外，如果某人编写了一个方法（通过这个链接的扩展库或其他方法获取日期，返回一个完成此操作的字符串），我将奖励他们答案。

Further to this, if someone composes a method (takes a date, returns a string) that accomplishes this, either with this linked extensions library or another method, I will award them the answer.

ED IT 2 Bounty适用于任何可以在Objective-C中编写模糊日期算法的人。

EDIT 2 Bounty goes to whoever can write the fuzzy date algorithm in Objective-C.

创建静态类方法：

+ (NSString *)stringForTimeIntervalSinceCreated:(NSDate *)dateTime serverTime:(NSDate *)serverDateTime{
    NSInteger MinInterval;
    NSInteger HourInterval;
    NSInteger DayInterval;
    NSInteger DayModules;   

    NSInteger interval = abs((NSInteger)[dateTime timeIntervalSinceDate:serverDateTime]);
    if(interval >= 86400)    
    {
        DayInterval  = interval/86400;
        DayModules = interval%86400;
        if(DayModules!=0)
        {
            if(DayModules>=3600){
                //HourInterval=DayModules/3600;
                return [NSString stringWithFormat:@"%i days", DayInterval];
            }
            else {
                if(DayModules>=60){
                    //MinInterval=DayModules/60;
                    return [NSString stringWithFormat:@"%i days", DayInterval];
                }
                else {
                    return [NSString stringWithFormat:@"%i days", DayInterval];
                }
            }
        }
        else 
        {
        return [NSString stringWithFormat:@"%i days", DayInterval];
        }

    }

    else{

        if(interval>=3600)
        {

            HourInterval= interval/3600;
            return [NSString stringWithFormat:@"%i hours", HourInterval];

        }

        else if(interval>=60){

            MinInterval = interval/60;

            return [NSString stringWithFormat:@"%i minutes", MinInterval];
        }
        else{
            return [NSString stringWithFormat:@"%i Sec", interval];
        }

    }

}
