问题
I am trying to compare the time from two NSDate objects but am getting the wrong answer. I think it is because when using the NSDate compare methods it is also including the date. I just want to ignore the date and compare the times. How can this be done?
回答1:
well, you can always use NSCalendar's - (NSDate *)dateFromComponents:(NSDateComponents *)comps
