我希望能够使用ios 5的Twitter API将所有用户关注者和用户名关注到NSDictionary ...
虽然我遇到了障碍。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用户关注并关注的例子吗？
PS：我已经添加了Twitter框架，并导入了

这是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），这应该足以让您使用某种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);
}];
}
当您想要一个帐户的关注者时，它几乎相同...简单使用网址http://api.twitter.com/1/followers/ids.format并传递通过GET followers/ids找到的所需参数
希望这能为你提供一个良好的开端。

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

参考关于 runmad 帖子的评论＆＃34; [__ NSArrayI objectAtIndex：]的错误来源：索引0超出范围空数组＆＃34; 是你没有在模拟器中设置twitter帐户。您需要使用您的用户名和twitter提供的临时密码来签署Twitter。
其他错误来源是＆＃34; setObject表示密钥错误，密钥ID为nil＆＃34;。要克服以下代码类型： -
-(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.)
}
}];
}
-(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:@"https://api.twitter.com/1.1/followers/list.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];
NSLog(@"%@", twitterFriends);
}];
}
注意： - TWRequest已被弃用。因此，您也可以使用此代码段：
ACAccountStore *accountStore = [[ACAccountStore alloc] init];
ACAccountType *accountType = [accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierTwitter];
[accountStore requestAccessToAccountsWithType:accountType options:nil completion:^(BOOL granted, NSError *error){
if (granted) {
NSArray *accounts = [accountStore accountsWithAccountType:accountType];
// Check if the users has setup at least one Twitter account
if (accounts.count > 0)
{
ACAccount *twitterAccount = [accounts objectAtIndex:0];
for(ACAccount *t in accounts)
{
if([t.username isEqualToString:twitterAccount.username])
{
twitterAccount = t;
break;
}
}
SLRequest *twitterInfoRequest = [SLRequest requestForServiceType:SLServiceTypeTwitter requestMethod:SLRequestMethodGET URL:[NSURL URLWithString:@"https://api.twitter.com/1.1/followers/list.json"] parameters:[NSDictionary dictionaryWithObjectsAndKeys:[NSString stringWithFormat:@"%@", twitterAccount.username], @"screen_name", @"-1", @"cursor", nil]];
[twitterInfoRequest setAccount:twitterAccount];
// Making the request
[twitterInfoRequest performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) {
dispatch_async(dispatch_get_main_queue(), ^{
// Check if we reached the reate limit
if ([urlResponse statusCode] == 429) {
NSLog(@"Rate limit reached");
return;
}
// Check if there was an error
if (error) {
NSLog(@"Error: %@", error.localizedDescription);
return;
}
// Check if there is some response data
if (responseData) {
NSError *error = nil;
NSArray *TWData = [NSJSONSerialization JSONObjectWithData:responseData options:NSJSONReadingMutableLeaves error:&error];
NSLog(@"TWData : %@", TWData);
}
});
}];
}
} else {
NSLog(@"No access granted");
}
}];
