推荐答案

没有必要手工计算，看看 NSCalendar 。如果你想获得两个日期之间的小时和分钟，请使用以下内容：

There's no need to calculate this by hand, take a look at NSCalendar. If you want to get the hours and minutes between two dates, use something like this:

NSCalendar *gregorianCalendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar]; NSUInteger unitFlags = NSHourCalendarUnit | NSMinuteCalendarUnit; NSDateComponents *components = [gregorianCalendar components:unitFlags fromDate:firstDate toDate:otherDate options:0]; [gregorianCalendar release];

您现在拥有NSDateComponents的小时和分钟，并可以 NSIntegers访问它们喜欢 [components hour] 和 [components minute] 。这也可以在几天，闰年和其他有趣的东西之间工作几个小时。

You now have the hours and minutes as NSDateComponents and can access them as NSIntegers like [components hour] and [components minute]. This will also work for hours between days, leap years and other fun stuff.
