IOS calculates how long the last date is from the current code _ios

This article is an example of how the iOS last date distance from the current calculation code for your reference, the details are as follows

/** * Calculate Last Date distance now * * @param lasttime Last date (required and format) * @param format1 Last date format * @param currenttime Recent date (required and format)
            * @param FORMAT2 Recent date format * * @return xx minutes ago, xx hours ago, xx days ago * * * + (NSString *) Timeintervalfromlasttime: (NSString *) lasttime Lasttimeformat: (NSString *) format1 tocurrenttime: (NSString *) currenttime currenttimefor
  Mat: (NSString *) format2{//last time NSDateFormatter *dateformatter1 = [[NSDateFormatter alloc]init];
  Dateformatter1.dateformat = FORMAT1;
  NSDate *lastdate = [DateFormatter1 datefromstring:lasttime];
  Current time NSDateFormatter *dateformatter2 = [[NSDateFormatter alloc]init];
  Dateformatter2.dateformat = FORMAT2;
  NSDate *currentdate = [DateFormatter2 datefromstring:currenttime];
return [Utilities timeintervalfromlasttime:lastdate tocurrenttime:currentdate]; } + (NSString *) Timeintervalfromlasttime: (NSDate *) lasttime tocurrenttime: (nsdate *) currenttime{NSTimeZone
  = [Nstimezone Systemtimezone]; Last time NSdate *lastdate = [Lasttime datebyaddingtimeinterval:[timezone secondsfromgmtfordate:lasttime]];
  Current time NSDate *currentdate = [currenttime datebyaddingtimeinterval:[timezone secondsfromgmtfordate:currenttime]]; Time interval Nsinteger intevaltime = [currentdate timeintervalsincereferencedate]-[Lastdate timeintervalsincereferencedate
 
  ];
  Seconds, minutes, hours, days, months, years nsinteger minutes = INTEVALTIME/60;
  Nsinteger hours = INTEVALTIME/60/60;
  Nsinteger day = intevaltime/60/60/24;
  Nsinteger month = INTEVALTIME/60/60/24/30;
 
  Nsinteger yers = intevaltime/60/60/24/365;
  if (minutes <=) {return @ "just";
  }else if (minutes <) {return [NSString stringWithFormat: @ '%ld minutes ago ', (long) minutes];
  }else if (Hours <) {return [NSString stringWithFormat: @ "%ld hours ago", (long) hours];
  }else if (Day <) {return [NSString stringWithFormat: @ "%ld days Ago", (long)];
   }else if (Month <) {NSDateFormatter * df =[[nsdateformatter Alloc]init]; Df.dateformat = @ "M month D Day";
    NSString * time = [DF stringfromdate:lastdate];
  return time;
    }else if (yers >= 1) {NSDateFormatter * df =[[nsdateformatter Alloc]init];
    Df.dateformat = @ "yyyy year M month D Day";
    NSString * time = [DF stringfromdate:lastdate];
  return time;
} return @ "";
 
 }

Use the following:

NSLog (@ "\n\nresult:%@", [Utilities timeintervalfromlasttime:@ "December 8, 2015 15:50" lasttimeformat:@ "yyyy
                      year mm month DD Day hh:mm "
                      tocurrenttime:@" 2015/12/08 16:12 "currenttimeformat:@" Yyyy/mm/dd "
                    ]);

The output results are as follows:
