摘要: OC时间格式转换封装

代码可能有点乱 不过应该不影响使用  这些应该基本上能满足大部分用户对于时间的处理需求

DateTimeHelper.h文件

#import <Foundation/Foundation.h>

@interface DateTimeHelper : NSObject

//时间戳转化成字符串格式日期 YYYY-MM-dd HH:mm
+(NSString*)dateTimeFromTimesp:(double)timeStamp;

//时间戳转化成字符串格式日期 YYYY-MM-dd HH:mm:ss
+(NSString*)dateTimeFromTimesp1:(double)timeStamp;

//时间戳转化成字符串格式日期 YYYY-MM-dd
+(NSString*)dateTimeFromTimespEx:(double)timeStamp;

//时间戳转化成字符串格式日期 YYYY年MM月dd日 ss时mm分
+(NSString*)dateTimeFromTimespNYR:(double)timeStamp;

//将时间戳转化成double
+(double)dateToTimesp:(NSDate*)aDate;

//获取当前日期是 几号
+(NSString*)currentDay;

//相对时间 N年N月N日后的日期     -数可以表示n年前的日期
+ (NSString *)relativeTime:(NSString *)dateStr years:(NSInteger)years month:(NSInteger)month day:(NSInteger)day;

//将秒处理成格式化的时间
+ (NSString *)getDateFormatWithStringSeconds:(NSString *)timerStr;

//获取当前系统时间格式化 参数为一个格式YYYY-MM-dd HH:mm:ss;  返回的格式和这个保持一致
+(NSString*)getCurrentSystemTime:(NSString*)formart;

//获取当前网络时间时间(中国)并转换成年月日分开 返回只根据需要自己修改
+(NSString*)getTimeSegment;

//将时间格式格式化成字符串《=》nsdate 转换成需要的string
+(NSString *)getStringFromDate:(NSDate*)inputDate format:(NSString *)format;

+ (NSTimeInterval)getDateWithReferenceRetureIntervalFrom1970:(NSString *)reference format:(NSString *)format;

//传入一个格式化过得字符串 返回与当前时间的间隔( 秒)  reference 为  时间字符串 参数为一个reference字符串的 格式根据需要自己填写(YYYY-MM-dd HH:mm:ss);
+ (NSTimeInterval)getDateWithReferenceRetureIntervalToNow:(NSString *)reference format:(NSString *)format;


//返回一个 NSTimeInterval 秒计算    刚刚   1分钟前 还是一周前..
+(NSString *)getTimeString:(NSTimeInterval)time;

@end
