關於日期問題的 求解答 求鞭撻 求滴蠟！！！！！！！！！
小弟想做一個頁面時間的小東西  
計時器已經做好了 
下面這個方法就是得到當前的系統時間的
我頁面有一個lable 
我打印又能打印出來。。。。。。。。。
但是我怎麼設置不進去lable的值了？？？？？
求解啊！！！！！！！！！！大神們

- (NSString*)get_system_today_time
{
NSDate *date = [NSDate date];
NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
[formatter setDateStyle:kCFDateFormatterMediumStyle];
[formatter setTimeStyle:kCFDateFormatterShortStyle];
[formatter setDateFormat:@"YYYY-MM-dd-hh-mm-ss"];
NSString *string_time = [formatter stringFromDate:date];
NSArray *time = [string_time componentsSeparatedByString:@"-"];

int value_year = [[time objectAtIndex:0]intValue];
int value_month = [[time objectAtIndex:1]intValue];
  int value_day = [[time objectAtIndex:2]intValue];
  int value_hour = [[time objectAtIndex:3]intValue];
  int value_minute = [[time objectAtIndex:4]intValue];
  int value_second = [[time objectAtIndex:5]intValue];
[formatter setDateFormat:@"EEEE"];
NSString *week_day = [formatter stringFromDate:date];
[formatter release];

lable_year.text = value_year;


NSString *system_time = [[NSString alloc] initWithFormat:@"{"year":"%d","month":"%d","day":"%d","hour":"%d","minute":"%d","second":"%d","week_day":"%@"}",value_year,value_month,value_day,value_hour,value_minute,value_second,week_day];
NSLog(@"nsystem time is %@",system_time);
return [system_time autorelease];
}
