有没有办法检查NSDate是本周还是下周?
我知道今天是:
[NSDate date]
然后我该怎么办?
最佳答案
使用NSDateComponents,如下所示:
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。
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。
