它是 Apple 的 Twitter API 和 Twitter 自己的 API 的组合。一旦你阅读了代码，它就相当简单了。我将提供有关如何获取 Twitter 帐户的“朋友”（这是用户关注的人的术语）的示例代码，这应该足以让您继续了解获取 Twitter 帐户的关注者的方法。帐户。
首先，添加Accounts and Twitter构架。
现在，让我们获取用户设备上存在的 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.)
}
}];
}
现在我们可以使用以下命令让朋友注册一个帐户获取好友/ID命令：
#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);
}];
}
当您想要一个帐户的关注者时，几乎是一样的......简单使用 URLhttp://api.twitter.com/1/followers/ids.format并传入通过找到的所需参数获取关注者/id
希望这能给您一个良好的开端。
UPDATE:
正如评论中指出的，您应该使用更新后的 API 调用：https://api.twitter.com/1.1/followers/list.json
