如何使用NSCalendar獲得星期幾？

Question

我想得到星期幾，最好是從1到7的整數......這可能嗎？

這是我目前要得到當前的小時，分​​鍾和秒....

NSCalendar *gregorian = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar]; 
NSDateComponents *dateComponents = [gregorian components:(NSHourCalendarUnit | NSMinuteCalendarUnit | NSSecondCalendarUnit) fromDate:[NSDate date]]; 

NSInteger hour = [dateComponents hour]; 
NSInteger minute = [dateComponents minute]; 
NSInteger second = [dateComponents second]; 

Answer 1

您可以使用此：

NSDateComponents *weekdayComponents =[gregorian components:NSWeekdayCalendarUnit fromDate:myDate]; 

NSInteger weekday = [weekdayComponents weekday]; 

或與你的代碼已經整合有：

NSDateComponents *dateComponents = [gregorian components:(NSHourCalendarUnit | NSMinuteCalendarUnit | NSSecondCalendarUnit | NSWeekdayCalendarUnit) fromDate:[NSDate date]]; 

NSInteger weekday = [dateComponents weekday]; 

這會讓你值1 .. 7其中1是星期天。

希望有所幫助。
