Question

我有EDSunriseSet的日出时间和日落时间，现在我需要将其与当前时间进行比较以获得夜间模式：

NSCalendar *todayCal = [NSCalendar currentCalendar];
NSDateComponents *todayComp = [todayCal components: NSCalendarUnitHour | NSCalendarUnitMinute | NSCalendarUnitSecond fromDate:[NSDate date]];


BOOL nightMode;

if (todayComp.date > sunriseSet.localSunrise.date & todayComp.date < sunriseSet.localSunset.date) {
    nightMode = NO;

} else {
    nightMode = YES;

}


if (nightMode) {
    NSLog(@"the current is night zzzzzzzzzzz PM");

} else {
    NSLog(@"the current is day ........... AM");

}

但是它没有用!!

日出：5：18：4 - 日落：18：41：50

当前时间：19：54：13

检查此代码是否正常工作

NSCalendar *todayCal = [NSCalendar currentCalendar];
NSDateFormatter *dateFormater = [[NSDateFormatter alloc]init];
[dateFormater setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
NSDate *startDate = [dateFormater dateFromString:@"2017-04-16 05:18:04"];
NSDate *EndDate = [dateFormater dateFromString:@"2017-04-16 18:41:50"];
NSDate *CurrentDate = [dateFormater dateFromString:@"2017-04-16 15:54:13"];

BOOL nightMode;
if (CurrentDate > startDate & CurrentDate < EndDate) {
     nightMode = NO;

} else {
    nightMode = YES;

}
if (nightMode) {
    NSLog(@"the current is night zzzzzzzzzzz PM");
} else {
    NSLog(@"the current is day ........... AM");
}
