Question

i am using following code to get months correctly....it returns correct data..but it gives 2 months when i get from two dates...suppose if i give two dates like janauary to march, it will give 2 months...how can i change to no of days exactly(included feb)...

NSCalendar *sysCalendar = [NSCalendar currentCalendar];


unsigned int unitFlags = NSSecondCalendarUnit | NSHourCalendarUnit | NSMinuteCalendarUnit | NSDayCalendarUnit | NSMonthCalendarUnit;

NSDateComponents *breakdownInfo = [sysCalendar components:unitFlags fromDate:date1  toDate:date2  options:0];

NSLog(@"Break down: %dmons", [breakdownInfo month]);

Answer 1

You could use NSDateComponents , but you can count days simply by taking the difference of each date's timeInterval. NSTimeInterval is a floating point number that counts the number of seconds.

#define kSecondsInDay 86400

int numberOfDays = [date2 timeIntervalSinceDate:date1] / kSecondsInDay;

Answer 2

通过仅在创建日期组件时指定NSDayCalendarUnit标志，您将获得[breakdownInfo day]结果的[breakdownInfo day] 。
