NSDateComponentsを使用して日、月、年、時、分などを別々に取得していますが、2017-11-08 1:00:00 ....誰が私が行方不明を知っていますか?NSDateComponentsが正確な日/月/年の時間を表示しない
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:@"yyyy-MM-dd hh:mm:ss"];
NSDate *date = [dateFormatter dateFromString:@"2017-11-08 1:00:00"];
NSCalendar *calendar = [NSCalendar currentCalendar];
NSDateComponents *components = [calendar components:(NSCalendarUnitHour | NSCalendarUnitMinute) fromDate:date];
NSInteger day = [components day];
NSInteger month = [components month];
NSInteger year = [components year];
NSInteger hour = [components hour];
NSInteger minute = [components minute];
NSInteger second = [components second];
NSLog(@"day: %ld",(long)day);
NSLog(@"month: %ld",(long)month);
NSLog(@"year: %ld",(long)year);
NSLog(@"hour: %ld",(long)hour);
NSLog(@"minute: %ld",(long)minute);
NSLog(@"second: %ld",(long)second);
出力:
day: 2147483647
month: 2147483647
year: 2147483647
hour: 1
minute: 0
second: 2147483647
