iPhone-Twitter API获得用户关注/关注

我希望能够使用ios 5的Twitter API将所有用户关注者和后续用户名放入

NSDictionary

不过我遇到了一个路障。我不知道如何使用Twitter API来做这件事。。。但是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请求来查找此用户的追随者

有没有人能给我举个例子，让你的Twitter用户关注你和关注你

---

PS：我已经添加了Twitter框架，并导入了它，它是苹果的Twitter API和Twitter自己的API的组合。一旦你读了代码，它就相当直截了当了。我将提供示例代码，说明如何获取Twitter帐户的“好友”（这是用户关注的人的术语），这应该足以让您使用一种方法来获取帐户的关注者

首先，添加

账户

和

推特

框架

现在，让我们获取用户设备上的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.)
                                }
    }];
}

#导入命令：

#导入
-（无效）getTwitterFriendsForAccount:（ACAccount*）帐户{
//在本例中，我正在为该帐户创建字典
//添加帐户屏幕名称
NSMutableDictionary*accountDictionary=[NSMutableDictionary dictionaryWithObjectsAndKeys:account.username，@“screen_name”，nil]；
//添加用户id（在我的案例中我需要它，但执行请求时不需要它）
[accountDictionary setObject:[[account Dictionary WithValuesForkeys:[NSArray arrayWithObject:@“properties”]]objectForKey:@“properties”]objectForKey:@“user_id”]forKey:@“user_id”]；
//设置URL，正如您所看到的，它只是Twitter自己的API URL方案
NSURL*以下URL=[NSURL URLWithString:@”http://api.twitter.com/1/friends/ids.json"];
//传入参数（基本上是'.ids.json？screen_name=[screen_name]'））
NSDictionary*参数=[NSDictionary Dictionary WithObjectsAndKeys:account.username，@“screen_name”，nil]；
//设置请求
TWRequest*twitterRequest=[[TWRequest alloc]initWithURL:followURL
参数：参数
requestMethod:TWRequestMethodGET]；
//这很重要！请设置请求的帐户，以便我们可以执行经过身份验证的请求。如果没有此设置，您将无法获得私人帐户的关注者，如果您执行的请求太多，Twitter也可能会返回错误
[TwitterRequestSetAccount:account]；
//执行对Twitter好友的请求
[twitterRequest performRequestWithHandler:^（NSData*responseData，NSHTTPURLRResponse*URLRResponse，NSError*错误）{
如果（错误）{
//处理任何错误-请记住，尽管您可能会收到包含错误的有效响应，因此您可能希望查看响应并确保字典中不存在“error:”键
}
n错误*jsonError=nil；
//将响应转换为字典
NSDictionary*twitterFriends=[NSJSONSerialization JSONObject WithData:responseData选项：NSJSONWriting预打印错误：&jsonError]；
//抓取Twitter返回的ID并将它们添加到我们之前创建的字典中
[accountDictionary setObject:[twitterFriends objectForKey:@“ids”]forKey:@“friends_ids”]；
NSLog（@“%@”，accountDictionary）；
}];
}

当你想要一个帐户的追随者，它几乎是一样的。。。简单使用URL
http://api.twitter.com/1/followers/ids.format
并通过

希望这能给你一个良好的开端

更新：

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

#导入“FHSTwitterEngine.h”

添加SystemConfiguration.framework

将以下代码写入viewDidLoad（用于oauth登录）

UIButton*logIn=[UIButton-button-with-type:uibuttontyperoundrect]；
logIn.frame=CGRectMake（100100100100）；
[登录设置标题：@“登录”状态：UIControlStateNormal]；

NSMutableArray*数组=[dict1 objectForKey:@“用户”]；
对于（int i=0；i
参考runmad帖子上的评论，“[\uu NSArrayI objectAtIndex:]：索引0超出空数组的界限”的错误源是您尚未在模拟器中设置twitter帐户。您需要使用您的用户名和twitter提供的临时密码在twitter上签名
