感谢你们,我已成功将我的字符串数组转换为NSDates。现在我想检查今天的日期是否在我的两个日期之间(即从日期到日期)。我已经看到了以下问题,但未能在我的代码中实现它们。很棒我可以使用任何其他方法或帮助使用用户提供的解决方案。
NSDate between two given NSDates
How to Check if an NSDate occurs between two other NSDates
How can I check if an NSDate falls in between two other NSDates in an NSMutableArray
这就是我目前所拥有的:
NSDateFormatter *format = [[NSDateFormatter alloc] init];
[format setDateFormat:@"yyyy-MM-dd"];
NSTimeZone *tz = [NSTimeZone localTimeZone];
[format setTimeZone:tz];
NSDate *now = [[NSDate alloc] init];
NSString *todaysDate = [format stringFromDate:now];
NSLog(@"todaysDate: %@", todaysDate);
//converting string - date
int size = [appDelegate.ALLevents count];
for (NSUInteger i = 0; i < size; i++) {
Event *aEvent = [appDelegate.ALLevents objectAtIndex:i];
//Convert fromDate
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"dd-MM-yyyy"];
NSDate *fromDate = [dateFormatter dateFromString:aEvent.fromDate];
[dateFormatter setTimeZone:tz];
NSLog(@"fromDate: %@", fromDate);
//Convert toDate
NSDate *toDate = [dateFormatter dateFromString:aEvent.toDate];
NSLog(@"toDate: %@", toDate);
[dateFormatter release];
//Compare if today falls in between
//codes here
}
答案 0 :(得分:5)
执行以下操作,
NSTimeInterval fromTime = [fromDate timeIntervalSinceReferenceDate];
NSTimeInterval toTime = [toDate timeIntervalSinceReferenceDate];
NSTimeInterval currTime = [[NSDate date] timeIntervalSinceReferenceDate];
NSTimeInterval基本上是一个双重类型,因此如果currTime大于1且小于日期落在这两个NSDates之间,则可以比较它。
