想要从twitter到iPhone应用程序显示好友列表

Question

我正在使用推特和iOS 5帐户框架.问题是我无法使用http://api.twitter.com/1/friends/ids.json?screen_name=%@ "这个api 获取朋友列表但是从twitter api explorer,我得到了朋友列表.(twitter explorer api = https://dev.twitter.com/console).

Answer 1

我正在使用Twitter Native Framework for iOS.

要从Twitter获取朋友列表,您可以采用这种方式(四步).

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请求从Twitter获取好友ID列表.
4. 最后,您可以通过ID获取好友名称或其他数据并放入数组

所以...你的.h文件应该是这样的

#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;

你的.m文件应该有这样的..

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.
    }                                

  }];
}
