-(NSString *) toJson:(NSMutableDictionary*)dic{    // 轉換成json    NSString * string =[dic JSONString];        NSUInteger length = [string length];    NSMutableString *s = [NSMutableString stringWithCapacity:0];    

    // 全形沒有轉換成unicode，再進行轉換    for (int i = 0;i < length; i++)    {        const char *p;                NSString * isChar = [string substringWithRange:NSMakeRange(i, 1)];                p = [isChar UTF8String];                // 判斷是不是全形字元        if ((*p)&0x80) {            NSString *str = [NSString stringWithFormat:@"\\u%x", [string characterAtIndex:i]];            if (str.length == 6) {                [s appendString:str];            } else {                str = [NSString stringWithFormat:@"\\u00%x", [string characterAtIndex:i]];                                [s appendString:str];            }        } else {            [s appendFormat:@"%@",[string substringWithRange:NSMakeRange(i, 1)]];        }    }        return s;}

轉換結果："KEY1\":\"\\u6d41\\u91d1\\u5c81\\u6708\\u7cfb\\u5217 48\",\"KEY2\":\"312201\",\"KEY3\":\"310101\"  。。。。。。
