this question has answer here: how compare 2 nsdates: more recent? 13 answers i working method , not giving me proper output came know, way comparing date , time object wrong. googled not find relevant solution. want compare date , time object object. for example: if (dtcur >= dtstart && dtcur <= mydt) // 2014-03-24 11:30:00 >= 2014-03-24 11:00:00 & 2014-03-24 11:30:00 <= 2014-03-25 11:00:00 { // should come here in if condition } but goes in else. means comparison wrong, can me how compare 2 date , time objects. in advance many objects, including nsdate, have compare: method. use so: if ([date1 compare:date2] == nsorderedascending) { // date2 after date1 } else if ([date1 compare:date2] == nsordereddescending) { // date2 before date1 } else if ([date1 compare:date2] == nsorderedsame) { // they're both sa...
