有人用上AFNetworking 2.0了吗？
AFHTTPRequestOperationManager *manager=[AFHTTPRequestOperationManager manager];
manager.responseSerializer=[AFJSONRequestSerializer serializer];
[manager GET:@"http://www.weather.com.cn/data/sk/101190101.html" parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject){
NSLog(@"traces:%@",responseObject);
}failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(@"Error: %@", error);
}];
解析一个json接口是这样用吗？为啥不行？
