在JSON中如何让数组正常显示

我要在JSON中发送数组

代码如下：

-(void)getConnection {    NSArray *comment=[NSArray arrayWithObjects:@""aaa""@""bbb""@""ccc""@""helloyestell"" nil];    NSURL *aurl=[NSURL URLWithString:@""http://sajalaya.com/taskblazer/staffend/form/iphonearraytest.php""];    NSMutableURLRequest *request=[NSMutableURLRequest requestWithURL:aurl cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];    [request setValue:@""application/x-www-form-urlencoded"" forHTTPHeaderField:@""Content-Type""];    [request setHTTPMethod:@""POST""];   NSData *jsonData2 = [NSJSONSerialization dataWithJSONObject:comment options:NSJSONWritingPrettyPrinted error:nil];   NSString *new = [[NSString alloc] initWithData:jsonData2 encoding:NSUTF8StringEncoding]; // NSString *new = [comment JSONString]; // NSArray *new=[comment jsonvalue];    NSString *postString=[NSString stringWithFormat:@""tag=&comment=%@&total=%@""new@""4""];    NSLog(@""this is post string%@""postString);    [request setHTTPBody:[postString dataUsingEncoding:NSUTF8StringEncoding]];     [NSURLConnection connectionWithRequest:request delegate:self];       }
