NSDate *date = [NSDate Date];
Nstimezone *zone = [Nstimezone systemtimezone];//Modify Time zone
Nsinteger interval1 = [Zone secondsfromgmtfordate:date];//modify Time zone
NSDate *localdate1 = [date datebyaddingtimeinterval:interval1];//modify time zone
NSLog (@ "Today%@", localDate1);
2), create a date for tomorrow at this time (the interval is in seconds) Datewithtimeintervalsincenow:
NSDate *tomorrow = [nsdate datewithtimeintervalsincenow:24 * 60 * 60];
Nsinteger interval2 = [zone Secondsfromgmtfordate:tomorrow];
NSDate *localdate2 = [Tomorrow Datebyaddingtimeinterval:interval2];
NSLog (@ "Tomorrow%@", localDate2);
3), create a date at this time yesterday
NSDate *yesterday = [nsdate datewithtimeintervalsincenow:-24 * 60 * 60];
Nsinteger interval3 = [zone secondsfromgmtfordate:yesterday];
NSDate *localdate3 = [Yesterday Datebyaddingtimeinterval:interval3];
NSLog (@ "Yesterday%@", localDate3);
