我正在使用iOS的Twitter Native Framework.

要从Twitter获取朋友列表，您可以采用这种方式(四个步骤).

To getting friends list from Twitter you can go this way (Four Steps).

1. 将Twitter和Accounts Framework添加到项目中.
2. 获取当前的Twitter帐户实例.
3. 然后您将通过API从Twitter获得好友ID列表 请求.
4. 最后，您可以通过ID获得好友名称或其他数据， 放入数组

1. Add Twitter and Accounts Framework to project.
2. Get The Current Twitter Account Instance.
3. Then you will get the Friends ID list from Twitter through API Request.
4. And finally you can get the Friends Name or other data via ID and put in Array

所以...您的.h文件应该看起来像这样

so...your .h file should look like this

#import <UIKit/UIKit.h>
#import <Twitter/Twitter.h>
#import <Accounts/Accounts.h>

@interface LoginView : UIViewController{    

    ACAccount *myAccount;  
    NSMutableString *paramString;  
    NSMutableArray *resultFollowersNameList;
}

@property(nonatomic,retain) ACAccount *myAccount;
@property(nonatomic, retain) NSMutableString *paramString;
@property(nonatomic, retain) NSMutableArray *resultFollowersNameList;

，并且您的.m文件应该是这样的.

and your .m file should have like this..

Get The Twitter Account Instance
/******To check whether More then Twitter Accounts setup on device or not *****/

-(void)getTwitterAccounts {

    ACAccountStore *accountStore = [[ACAccountStore alloc] init];    
    ACAccountType *accountType = [accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierTwitter];   
    [accountStore requestAccessToAccountsWithType:accountType
                            withCompletionHandler:^(BOOL granted, NSError *error) {

    if (granted && !error) {
        accountsList = [accountStore accountsWithAccountType:accountType]; 

        int NoOfAccounts = [accountsList count]; 

        if (NoOfAccounts > 1) {      

            NSLog(@"device has more then one twitter accounts %i",NoOfAccounts);

        } 
        else 
        {
            myAccount = [accountsList objectAtIndex:0];             
            NSLog(@"device has single twitter account : 0");           

        }
    } 
    else 
    {
        // show alert with information that the user has not granted your app access, etc.
    }                                

  }];
}
