NSCalendar dateWithComponents出現誤導日期

Question

我必須制定一個日期dateComponents：

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); 

日曆具有正確的時區，日期的所有組件都是權利。那麼， 無論我做什麼，itemDate對象都有格林威治時區（+0000）。我應該如何解決這個問題？

解決方案自從日期正確的那一刻起，問題就不存在了，NSDate描述始終以GMT時間輸出。 要查看正確的格式，您應該使用descriptionWithLocale，請檢查此文檔。
