可可 - 計算兩個日期之間的工作日

Question

我是可可程序設計的新手，我想知道如何獲得日期之間的工作日數。所以只能從星期一到星期五。謝謝。

Answer 1

NSDate *startDate = ...; 
NSDate *stopDate = ...; 

NSDateFormatter *df = [NSDateFormatter new]; 
df.dateFormat = @"yyyy-MM-dd"; 
startDate = [df dateFromString:[df stringFromDate:startDate]]; // get start of the day 

NSDateComponents *comps = [NSDateComponents new]; 
comps.day = 1; // one day in NSDateComponents 

NSUInteger count = 0; 
while ([stopDate timeIntervalSinceDate:startDate] >= 0) { 

    NSInteger weekday = [[NSCalendar currentCalendar] components:NSCalendarUnitWeekday fromDate:startDate].weekday; 

    if (weekday != 1 && weekday != 6) ++count; // filter out weekend days - 6 and 1 

    startDate = [[NSCalendar currentCalendar] dateByAddingComponents:comps toDate:startDate options:0]; // increment start day 
}
