使用自述文件中的示例时AFNetworking异常

Question

我还提交了一个问题here。

使用自述文件中的代码：

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager GET:@"http://www.google.com" parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"JSON: %@", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error: %@", error);
}];

抛出以下异常：

2013-09-27 22:16:10.345 Grades[1000:60b] -[AFHTTPRequestOperation setResponseSerializer:]: unrecognized selector sent to instance 0x1666c3f0

我已确认所有AFNetworking文件都已更新为2.0。

如何解决此异常？

问题是某些文件未正确更新。尝试从项目目录中删除所有AFNetworking文件，清理并构建，安装新文件，然后再次清理和构建。
