AFN网络的iOS块问题

我目前正在学习积木，我想将它们用于

AFNetworking

。我用单音制作方法：

- (void)getAllPlayers:(void (^)(NSArray *playerz, bool succeed))blockPlayers {
    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    [manager GET:@"https://api.myjson.com/bins/530re" parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {



    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSLog(@"Error: %@", error);
    }];

}

我在viewDidLoad中调用了此方法：

[[Manager sharedInstance]getAllPlayers:^(NSArray *playerz, bool succeed) {
            if (succeed == YES) {
                self.allClubs = playerz;
                [self.tableView reloadData];
            }
        }];

但是没有下载任何内容。
您忘记调用blockPlayers完成处理程序了

- (void)getAllPlayers:(void (^)(NSArray *playerz, bool succeed))blockPlayers {
    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    [manager GET:@"https://api.myjson.com/bins/530re" parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {

        NSarray *returnedPLayerz = [NSArray array];
        //Here treat operation and response Object to extract playerz and assing it to returnedPlayerz
        blockPLayers(returnedPlayerz, YES);

    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        blockPlayers(nil, NO);
        NSLog(@"Error: %@", error);
    }];

}

您从响应对象中的服务器获取了数据。之后，您需要对其进行解析并在块中返回：

- (void)getAllPlayers:(void (^)(NSArray *playerz, bool succeed))blockPlayers {
  AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
  [manager GET:@"https://api.myjson.com/bins/530re" parameters:nil 
  success:^(AFHTTPRequestOperation *operation, id responseObject) {

     NSArray* players = [self getPlayersFromJson:responseObject];
     blockPlayers(players, YES); 

  } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
     blockPlayers(nil, NO);
  }];

}

---

因此，您需要创建解析器方法getPlayersFromJson

什么是“未下载任何内容”？有错误吗？您是否从成功块中剪切了代码，或者它实际上是空的？您需要在网络调用的完成处理程序中调用传入到

GetAllPlayer

的块。我不明白？我对iOS开发基本上是新手。
