iPhone- Twitter API GET用户关注者/关注者

Question

我希望能够使用ios 5的Twitter API来获取所有用户关注者和关注用户名NSDictionary...

我虽然遇到了障碍.我不知道如何使用Twitter API这样做...但我的主要问题是首先获取用户的用户名.当我甚至不知道用户的用户名时,如何发出API请求来查找此用户关注者？

有人能给我一个关于让你的Twitter用户关注者和关注者的例子吗？

PS:我已经添加了Twitter框架,并已导入

它是Apple的Twitter API和Twitter自己的API的组合.一旦你阅读了代码,这是相当直接的.我将提供如何获取Twitter帐户的"朋友"的示例代码(这是用户关注的人的术语),这应该足以让您继续获取一个方法来获取关注者帐户.

首先,添加Accounts和Twitter框架.

现在,让我们在用户的设备上获取Twitter帐户.

#import <Accounts/Accounts.h>

-(void)getTwitterAccounts {
    ACAccountStore *accountStore = [[ACAccountStore alloc] init];
    // Create an account type that ensures Twitter accounts are retrieved.
    ACAccountType *accountType = [accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierTwitter];
    // let's request access and fetch the accounts
    [accountStore requestAccessToAccountsWithType:accountType
                            withCompletionHandler:^(BOOL granted, NSError *error) {
                                // check that the user granted us access and there were no errors (such as no accounts added on the users device)
                                if (granted && !error) {
                                    NSArray *accountsArray = [accountStore accountsWithAccountType:accountType];
                                    if ([accountsArray count] > 1) {
                                        // a user may have one or more accounts added to their device
                                        // you need to either show a prompt or a separate view to have a user select the account(s) you need to get the followers and friends for 
                                    } else {
                                        [self getTwitterFriendsForAccount:[accountsArray objectAtIndex:0]];
                                    }
                                } else {
                                    // handle error (show alert with information that the user has not granted your app access, etc.)
                                }
    }];
}

现在我们可以使用GET friends/ids命令获取帐户的朋友:

#import <Twitter/Twitter.h>

-(void)getTwitterFriendsForAccount:(ACAccount*)account {
    // In this case I am creating a dictionary for the account
    // Add the account screen name
    NSMutableDictionary *accountDictionary = [NSMutableDictionary dictionaryWithObjectsAndKeys:account.username, @"screen_name", nil];
    // Add the user id (I needed it in my case, but it's not necessary for doing the requests)
    [accountDictionary setObject:[[[account dictionaryWithValuesForKeys:[NSArray arrayWithObject:@"properties"]] objectForKey:@"properties"] objectForKey:@"user_id"] forKey:@"user_id"];
    // Setup the URL, as you can see it's just Twitter's own API url scheme. In this case we want to receive it in JSON
    NSURL *followingURL = [NSURL URLWithString:@"http://api.twitter.com/1/friends/ids.json"];
    // Pass in the parameters (basically '.ids.json?screen_name=[screen_name]')
    NSDictionary *parameters = [NSDictionary dictionaryWithObjectsAndKeys:account.username, @"screen_name", nil];
    // Setup the request
    TWRequest *twitterRequest = [[TWRequest alloc] initWithURL:followingURL
                                                parameters:parameters
                                             requestMethod:TWRequestMethodGET];
    // This is important! Set the account for the request so we can do an authenticated request. Without this you cannot get the followers for private accounts and Twitter may also return an error if you're doing too many requests
    [twitterRequest setAccount:account];
    // Perform the request for Twitter friends
    [twitterRequest performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) {
                if (error) {
                    // deal with any errors - keep in mind, though you may receive a valid response that contains an error, so you may want to look at the response and ensure no 'error:' key is present in the dictionary
                }
                NSError *jsonError = nil;
                // Convert the response into a dictionary
                NSDictionary *twitterFriends = [NSJSONSerialization JSONObjectWithData:responseData options:NSJSONWritingPrettyPrinted error:&jsonError];
                // Grab the Ids that Twitter returned and add them to the dictionary we created earlier
                [accountDictionary setObject:[twitterFriends objectForKey:@"ids"] forKey:@"friends_ids"];
                NSLog(@"%@", accountDictionary);
    }];
}

当你想要一个帐户的关注者时,它几乎是一样的......简单地使用URL http://api.twitter.com/1/followers/ids.format并传递通过GET关注者/ ids找到的所需参数

希望这能为您提供良好的开端.

更新:

正如评论中指出的那样,您应该使用更新的API调用: https://api.twitter.com/1.1/followers/list.json
