Pokeapi 和获取 resource_uri

Question

所以我使用 AFNetworking 和 pokeapi 来获取 pokemon 列表。我可以让 tableview 加载，标题是口袋妖怪的名字。但我希望字幕是类型。所以我将基数设置为 #define pokeApiBaseURL [NSURL URLWithString: @"http://pokeapi.co/"]

这是我的请求的样子。我制作了一个数组，它为我提供了 url 的下半部分，我需要解析并获取类型和口袋妖怪的所有其他信息。但我似乎无法弄清楚如何使 baseURL 和 resource_uri 为我创建一个新的 url 来解析。

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];

这是我将它添加到单元格的地方

- (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;

}

我想您可能正在寻找这种将资源与基础结合起来的方法：

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

今天早上我有一些空闲时间，因为客户没有回复我，所以我做了这个：https://github.com/AlexTrott/PokeAPI：远非完美，这只是向您展示如何首先在本地存储数据加载，如果您有任何问题，请告诉我。

这里是获取您想要的 URL 和信息的方法(I used AFHTTPSessionManager as the method you use is about to be deprecated in AFN3) :

-(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);
    }];
}

我认为你需要重新考虑如何处理这个问题，我刚刚查看了 poke api，要执行你想要的操作，你必须进行 779 次调用，1 次是 pokedex 调用，然后另一个是778宝可梦

你可以通过删除 pokedex 请求，然后根据数据形成一个数组，将这个降低一个，但是你正在做 778 请求，这在我看来是疯狂的，我认为你需要解决你想如何显示数据，如果你最好不要第一次加载，或者你自己编译数据并在本地拥有它，因为 778 请求是疯狂的。

如果您确实必须执行那么多请求，请确保它只执行一次，并且是在他们第一次加载应用程序或其他内容时，然后存储在 CD 或领域或其他内容中。

有关将数据放入一个已排序的 NSMutableArray 的非常快速但肮脏的示例，请看一下这个，我不会这样做，我会对其进行批处理或在加载时存储在本地，但它应该让你更好地了解你想做什么。

#import "ViewController.h"
#import <AFNetworking/AFNetworking.h>

@interface ViewController () {
    NSString *pokeApiBaseURL;
    NSMutableArray *pokedex;
}

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(updateTable) name:@"orginalDone" object:nil];
    pokeApiBaseURL = @"http://pokeapi.co/";
    pokedex = [[NSMutableArray alloc] init];
    for (int i = 0; i < 151; i++) {
        [self loadData:i];
    }
}

- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
}


-(void)loadData:(int)pokemonID {
    NSString *url = [NSString stringWithFormat:@"http://pokeapi.co/api/v1/pokemon/%d/", pokemonID];
    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
    [manager GET:url parameters:nil success:^(NSURLSessionTask *task, id responseObject) {
        [self addPokemon:responseObject];
    } failure:^(NSURLSessionTask *operation, NSError *error) {
        NSLog(@"Error: %@", error);
    }];
}

-(void)addPokemon:(id)pokemonObject {
    NSMutableDictionary *pokemonData = [[NSMutableDictionary alloc] init];
    [pokemonData setObject:pokemonObject[@"pkdx_id"] forKey:@"pkmnID"];
    [pokemonData setObject:pokemonObject[@"name"] forKey:@"pokemonName"];
    NSMutableArray *types = [[NSMutableArray alloc] init];
    for (int i = 0; i < [pokemonObject[@"types"] count]; i++) {
        [types addObject:pokemonObject[@"types"][i][@"name"]];
    }
    [pokemonData setObject:types forKey:@"types"];
    [pokedex addObject:pokemonData];
    NSLog(@"count = %lu", (unsigned long)[pokedex count]);
    if ([pokedex count] == 150) {
        [[NSNotificationCenter defaultCenter] postNotificationName:@"orginalDone" object:nil];
    }
}

-(void)updateTable {
    NSLog(@"Unsorted = %@", pokedex);
    NSSortDescriptor *sort = [NSSortDescriptor sortDescriptorWithKey:@"pkmnID" ascending:YES];
    [pokedex sortUsingDescriptors:[NSArray arrayWithObject:sort]];
    NSLog(@"Sorted = %@", pokedex);
}
