在項目開發中從服務器中請求下來的時間想要處理

創建 Time 類 繼承NSObject
Time.h
#import <Foundation/Foundation.h>
@interface Time : NSObject
// 處理后返回
+ (NSString *)handleDate:(NSString *)dateString;
// 從服務器請求下來的
+ (NSString *)timeIntervalToDate:(NSString *)timeinterval;
@end
Time.m
#import "Time.h"
@implementation Time
/*
傳入時間與現在時間差距在60秒以內，輸出@“剛剛”
1個小時以內，輸出@“**分鐘前”
差距1-24小時以內，輸出@“**小時前”
差距24小時到48小時，輸出昨天
差距大于48小時，輸出@“完整日期”
*/
