NSCalendar dateWithComponents 给出错误的日期

Question

我必须用 dateComponents 来详细说明日期：

int year;
int month;
int day;
int hour;
int minute;
int second;
NSCalendar *calendar;
NSDate *actualDate;
NSDate *itemDate;
NSDateComponents *dateComps;
NSDateFormatter *dateFormatter;
UILocalNotification *sveglia;

actualDate = [NSDate date];
calendar = [[NSCalendar currentCalendar] copy];
dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setTimeZone:[calendar timeZone]];
[dateFormatter setDateFormat:@"yyyy"];
year = [[dateFormatter stringFromDate:actualDate] intValue];
[dateFormatter setDateFormat:@"MM"];
month = [[dateFormatter stringFromDate:actualDate] intValue];
[dateFormatter setDateFormat:@"dd"];
day = [[dateFormatter stringFromDate:actualDate] intValue];
[dateFormatter setDateFormat:@"HH"];
hour = [[dateFormatter stringFromDate:actualDate] intValue];
[dateFormatter setDateFormat:@"mm"];
minute = [[dateFormatter stringFromDate:actualDate] intValue];
[dateFormatter setDateFormat:@"ss"];
second = [[dateFormatter stringFromDate:actualDate] intValue];
dateComps = [[NSDateComponents alloc] init];
[dateComps setTimeZone:[calendar timeZone]];
[dateComps setDay:day];
[dateComps setMonth:month];
[dateComps setYear:year];
[dateComps setHour:hour];
[dateComps setMinute:minute];
// Obtaining date from components.
itemDate = [calendar dateFromComponents:dateComps];
NSLog(@"ItemDate: %@", itemDate);

日历具有正确的时区，日期的所有组件都是正确的。出色地， 无论我做什么，itemDate 对象都有格林威治时区（+0000）。我应该如何解决这个问题？

Answer 1

已解决...自从日期正确后，问题就不存在了，NSDate 描述始终给出 GMT 时间的输出。
要查看正确的格式，您应该使用descriptionWithLocale，请查看该格式的文档。
