string - 将 NSDate 转换为 NSString 时设置了错误的年份

Question

我试图以这种方式使用 NSDate 类别生成一个字符串:

NSString* dateString = nil;
NSDateFormatter *dateFormat = [[NSDateFormatter alloc] init];
[dateFormat setLocale:[NSLocal currentLocale]];
[dateFormat setDateFormat:@"dd LLL YYYY"];
dateString = [dateFormat stringFromDate:self];
return dateString;

转换工作正常，除了一种情况(我报告调试 session ): 如果我尝试像这样转换 NSDate 对象:

(gdb) po self
2012-01-01 00:00:00 +0000

我得到:

(gdb) po dateString
01 Jan 2011

为什么年份要回溯到2011年？？？

PS。我已经查过NSDate returns wrong year而且我没有使用日本日历。

非常感谢

试试这个:

     NSDate *pickerDate = [NSDate date];
     NSCalendar*       calendar = [[[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar] autorelease];
     NSDateComponents* components = [[[NSDateComponents alloc] init] autorelease];
        components.day = 0; //This value to take from today to next 1 or 2 or 3 days
        NSDate* newDate = [calendar dateByAddingComponents: components toDate: pickerDate options: 0];
        NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
        [dateFormatter setDateFormat:@"dd-MMMM"];
        NSString *textDate = [NSString stringWithFormat:@"%@",[dateFormatter stringFromDate:newDate]];
        [dateFormatter release];
