Pokeapi和获取resource_uri

Question

因此，我使用AFNetworking和pokeapi来获取pokemon的列表。我可以让表视图加载，标题是口袋妖怪的名称。但我希望副标题是那种。所以我把基础设为#define pokeApiBaseURL [NSURL URLWithString: @"http://pokeapi.co/"]

以下是我的请求。我创建了一个数组，它为我提供了我需要解析的url的下半部分，并得到了类型和所有口袋妖怪的其他信息。但我似乎想不出如何使baseURL和resource_uri创建一个新的url供我解析。

NSString *string = [NSString stringWithFormat:@"%@api/v1/pokedex/1/", pokeApiBaseURL];
NSURL *url = [NSURL URLWithString:string];
NSURLRequest *request = [NSURLRequest requestWithURL:url];

AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];

operation.responseSerializer = [AFJSONResponseSerializer serializer];
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {


    self.pokemonArray = [responseObject objectForKey:@"pokemon"];
    self.pokemonDetailArray = [[responseObject objectForKey:@"pokemon"]valueForKey:@"resource_uri"];




   // NSLog(@"\n%@",detailString);

    [self.tableView reloadData];
    [self.refreshControl endRefreshing];


} failure:^(AFHTTPRequestOperation *operation, NSError *error) {

    NSLog(@"Request Failed: %@, %@", error, error.userInfo);

}];

[operation start];

这是我把它加到牢房里的地方

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

static NSString *CellIdenifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdenifier forIndexPath:indexPath];


NSDictionary *pokemonDictionary = [self.pokemonArray objectAtIndex:indexPath.row];
NSDictionary *pokemonDetailDictionary = [self.pokemonDetailArray objectAtIndex:indexPath.row];


cell.textLabel.numberOfLines = 0;
cell.textLabel.lineBreakMode = NSLineBreakByWordWrapping;
[cell.textLabel sizeToFit];
cell.textLabel.text = [pokemonDictionary objectForKey:@"name"];
cell.detailTextLabel.text = @"PLACEHOLDER"; //WANT THE TYPE TO GO HERE!

return cell;

}

今天早上，我有一些空闲时间，因为一个客户没回我的电话，于是就提了这个问题：https://github.com/AlexTrott/PokeAPI：这并不完美，它只是向您展示如何在第一次加载时本地存储数据，如果您有任何问题要告诉我的话。

以下是如何获取您想要的https://github.com/AFNetworking/AFNetworking/wiki/AFNetworking-3.0-Migration-Guide的URL和信息)：

-(void)loadData {
    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
    [manager GET:@"http://pokeapi.co/api/v1/pokedex/1/" parameters:nil success:^(NSURLSessionTask *task, id responseObject) {
        pokemonArray = [responseObject objectForKey:@"pokemon"];
        pokemonDetailArray = [[responseObject objectForKey:@"pokemon"]valueForKey:@"resource_uri"];
        [self loop];
    } failure:^(NSURLSessionTask *operation, NSError *error) {
        NSLog(@"Error: %@", error);
    }];
}

-(void)loop {
    for (int i = 0; i < [pokemonArray count]; i++) {
        [self loadMore:i];
    }
}

-(void)loadMore:(int)pokemonID {
    NSString *url = [NSString stringWithFormat:@"%@%@", pokeApiBaseURL, [pokemonDetailArray objectAtIndex:pokemonID]];
    NSLog(@"URL = %@", url);
    NSLog(@"Loop Number = %d", pokemonID);
    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
    [manager GET:url parameters:nil success:^(NSURLSessionTask *task, id responseObject) {
        NSLog(@"response = %@", responseObject);
    } failure:^(NSURLSessionTask *operation, NSError *error) {
        NSLog(@"Error: %@", error);
    }];
}

我认为您需要重新考虑如何处理这个问题，我刚刚检查了poke api，为了做您想做的事情，您必须拨打779个电话，其中一个是pokedex调用，另一个是778口袋妖怪。

您可以通过删除pokedex请求来降低这个值，然后根据数据形成一个数组，但是然后执行778请求，在我看来，这是疯狂的，我认为您需要想出如何显示数据，如果第一次加载数据或者编译自己的数据并使其本地化，这是疯狂的，因为778请求是疯狂的。

如果你真的要这么做的话，一定要确保它只在第一次加载应用程序或其他东西的时候，然后存储在CD或领域之类的地方。

对于一个非常快速和肮脏的示例，要将您的数据放入一个排序的NSMutableArray中--看看这个，我不会这样做，我会对它进行批量处理，或者在加载时在本地存储，但是它会让您更好地了解您想要做的事情。

    [pokedex addObject:pokemonData];
    NSLog(@"count = %lu", (unsigned long)[pokedex count]);
    if ([pokedex count] == 150) {

    [pokedex sortUsingDescriptors:[NSArray arrayWithObject:sort]];
    NSLog(@"Sorted = %@", pokedex);

我认为您可能在寻找将资源与基本资源组合在一起的方法：

+ (instancetype)URLWithString:(NSString *)URLString
            relativeToURL:(NSURL *)baseURL

参考文件/occ/clm/NSURL/URLWithString:relativeToURL
