问题描述
有一种方法可以检查NSDate是本周还是下周?
there is a way to check if an NSDate is this week or is next week?
我知道今天是
[NSDate date]
那我该怎么办?
推荐答案
使用NSDateComponents,如下所示:
Use NSDateComponents, something like this:
NSCalendar *gregorian = [[NSCalendar alloc]
initWithCalendarIdentifier:NSGregorianCalendar];
NSDate *today = [NSDate date];
NSDateComponents *todaysComponents =
[gregorian components:NSWeekCalendarUnit fromDate:date];
NSUInteger todaysWeek = [todaysComponents week];
NSDate *anotherDate = [NSDate date];
NSDateComponents *otherComponents =
[gregorian components:NSWeekCalendarUnit fromDate:anotherDate];
NSUInteger anotherWeek = [otherComponents week];
if(todaysWeek==anotherWeek){
NSLog(@"another date is this week");
}else if(todaysWeek+1==anotherWeek){
NSLog(@"another date is next week")
}
您也可以使用其他组件(例如月份或年份)来完全确定.
You can also use other components like month or year to be completely sure.
注意:不要使用timeIntervals .通过使用NSDateComponents,您可以忽略小时,分钟和秒.我想你想要那个.
NOTE: Don't use timeIntervals. By using NSDateComponents you ignore the hour, minutes and seconds. I think you want that.
