IOS开发：解析服务器端的json数据

//连接字符串
NSString *urlstring = @"http://openapi.baidu.com/public/2.0/bmt/translate";
//构造request对象
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:urlstring]];
[request setHTTPMethod:@"GET"];
NSData *response = [NSURLConnection sendSynchronousRequest:request returningResponse:Nil error:nil];
//解析json数据到字典中,其中NSJSONReadingMutableContainers表示解析出的字典可以被修改
NSDictionary *dict = [NSJSONSerialization JSONObjectWithData:response options:NSJSONReadingMutableContainers error:Nil];
