please help me !!! thanks!

NSString *contentOfResponseDataInJsonValue = 
   [NSString stringWithContentsOfURL:url encoding:encoder=-2147483646 error:&error];
//                                                ^^^^^^^^^^^^^^^^^^^

What is this? You are using the encoding 0x80000002 which is not documented anywhere. Since translate.google.com is returning UTF-8 result, you should write

NSString *contentOfResponseDataInJsonValue = 
   [NSString stringWithContentsOfURL:url encoding:NSUTF8StringEncoding error:&error];

or let the system determines the encoding for you,

NSString *contentOfResponseDataInJsonValue = 
   [NSString stringWithContentsOfURL:url usedEncoding:&encoding error:&error];

I looked up the Unicode table, and indeed

• \U515c is 兜 ,
• \U639b is 掛 ,
• \U8e55 is 蹕 .

The combination of those three letters doesn't make sense to me (as a Japanese), but that's what you have in JSON data.
