如何将本地时间转化为"指定时区"的时间

1. NSDateFormatter *formatter =  [[NSDateFormatter alloc] init];
   
2. 
   
3. [formatter setDateFormat:@"yyyy-MM-dd hh:mm:ss"];
   
4. 
   
5. NSTimeZone* timeZone = [NSTimeZone timeZoneWithName:@"Asia/Shanghai"];
   
6. 
   
7. [formatter setTimeZone:timeZone];
   
8. 
   
9. NSString *loctime = [formatter stringFromDate:date];
   
10. 
    
11. [formatter release];

----------------------------------------------------------------------------------------------------

不管用户如何设置,,均获得24小时显示(其中的HH,强制指定为24时制)

1. NSDateFormatter * formatter =   [[NSDateFormatter alloc] init];
   
2. 
   
3. [formatter setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
   
4. 
   
5. NSString *loctime = [formatter stringFromDate:date];
   
6. 
   
7. [formatter release]
