MHPrettyDate 是一个 iOS 框架，提供了一种从 NSDate 对象获得 "Pretty Dates" ("昨天"，"今天" 等) 的简单机制。
#import "MHPrettyDate.h"typedef enum
{
MHPrettyDateFormatWithTime,
//
// EXAMPLE: if today is September 30, 2012 and the time is 12:58 PM
// Today: 12:58 PM
// Tomorrow: Tomorrow 12:58 PM
// Yesterday: Yesterday 12:58 PM
// 2 days ago: Friday 12:58 PM
// 1 week ago: 09/23/12 12:58 PM
// 1 week later: 10/07/12 12:58 PM
//
MHPrettyDateFormatNoTime,
//
// EXAMPLE: if today is September 30, 2012 and the time is 12:58 PM
// Today: Today
// Tomorrow: Tomorrow
// Yesterday: Yesterday
// 2 days ago: Friday
// 1 week ago: 09/23/12
// 1 week later: 10/07/12
//
MHPrettyDateFormatTodayTimeOnly,
//
// EXAMPLE: if today is September 30, 2012 and the time is 12:58 PM
// Today: 12:58 PM
// Tomorrow: Tomorrow
// Yesterday: Yesterday
// 2 days ago: Friday
// 1 week ago: 09/23/12
// 1 week later: 10/07/12
//
MHPrettyDateLongRelativeTime,
//
// EXAMPLES:
// Now
// 15 minutes ago
// 59 minutes ago
// 1 hour ago
// 2 hours ago
// Yesterday
// 30 days ago
// 90 days ago
//
// (future times same as MHPrettyDateFormatWithTime)
//
MHPrettyDateShortRelativeTime
//
// EXAMPLES:
// Now
// 15m
// 59m
// 1h
// 23h
// 1d
// 30d
// 90d
//
// (future time but today same as MHPrettyDateFormatWithTime, otherwise same as MHPrettyDateFormatNoTime)
//
