我需要检查一个事件日期,它应该在当前日期和从现在起 60 天之间。使用了下面的代码,但它不能正常工作。请注意,我正在从我的服务器获取这样的事件字符串 - “2012-04-14T16:50:02Z”。
// current date
double currDateInMilliSecs = [NSDate timeIntervalSinceReferenceDate] * 1000;
NSLog(@"currDateInMilliSecs: %f", currDateInMilliSecs);
// sixty days
double sixtydaysvalue = 60.0 * 24.0 * 3600.0 * 1000.0;
NSLog(@"sixtydaysvalue: %f", sixtydaysvalue);
// add current date + sixt days
double sixtyDaysMilliSecsFromCurrDate = currDateInMilliSecs + sixtydaysvalue;
NSLog(@"sixtyDaysMilliSecsFromCurrDate: %f", sixtyDaysMilliSecsFromCurrDate);
// check does the event date between current date + 60 days
NSDateFormatter *df = [[NSDateFormatter alloc] init];
//[df setTimeZone:[NSTimeZone timeZoneWithName:@"UTC"]];
[df setDateFormat:@"yyyy-MM-dd'T'HH:mm:ss'Z'"];
//[df setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
// [eventDict objectForKey:@"begin_at"] gives date string like this "2012-04-14T16:50:02Z" for ex.
NSDate *eventdate = [df dateFromString:[eventDict objectForKey:@"begin_at"]];
NSTimeInterval nowSinceEventDate = [eventdate timeIntervalSince1970];
NSLog(@"nowSinceEventDate: %f", nowSinceEventDate);
double eventDateInMilliSecs = nowSinceEventDate * 1000;
NSLog(@"eventDateInMilliSecs: %f", eventDateInMilliSecs);
// this is not working as expected
if ( eventDateInMilliSecs<sixtyDaysMilliSecsFromCurrDate && eventDateInMilliSecs>currDateInMilliSecs )
{
}
else
{
}
