Twitter 已弃用其 API 1.0 并实施了新的 API 1.1 根据新的 API，我们需要在获取公共时间线之前进行身份验证。

我在这里阅读了新的 API 文档：https ://dev.twitter.com/docs/api/1.1 但我不清楚如何在 iOS 中实现它。

谁能告诉我使用 API 1.1 从 Twitter 获取公共时间线的最佳方法

提前致谢。

首先，您需要Authenticate您的请求（获得许可）。

其次，请参阅以下步骤：

1.下载FHSTwitterEngine推特库。

2.将文件夹FHSTwitterEngine“添加到您的项目中，然后#import "FHSTwitterEngine.h".

3.添加SystemConfiguration.framework到您的项目中。

用法： 1.在[ViewDidLoad]添加以下代码。

UIButton *logIn = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    logIn.frame = CGRectMake(100, 100, 100, 100);
    [logIn setTitle:@"Login" forState:UIControlStateNormal];
    [logIn addTarget:self action:@selector(showLoginWindow:) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:logIn];

[[FHSTwitterEngine sharedEngine]permanentlySetConsumerKey:@"<consumer_key>" andSecret:@"<consumer_secret>"];
    [[FHSTwitterEngine sharedEngine]setDelegate:self];
and don't forget to import the delegate FHSTwitterEngineAccessTokenDelegate.

you need to get the permission for your request, with the following method which will present Login window:
- (void)showLoginWindow:(id)sender {
    [[FHSTwitterEngine sharedEngine]showOAuthLoginControllerFromViewController:self withCompletion:^(BOOL success) {
        NSLog(success?@"L0L success":@"O noes!!! Loggen faylur!!!");
    }];
}

当出现登录窗口时，输入您的Twitter用户名和密码以验证您的请求。

将以下方法添加到您的代码中：

-(void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];
    [[FHSTwitterEngine sharedEngine]loadAccessToken];
    NSString *username = [[FHSTwitterEngine sharedEngine]loggedInUsername];// self.engine.loggedInUsername;
    if (username.length > 0) {
        lbl.text = [NSString stringWithFormat:@"Logged in as %@",username];
        [self listResults];


    } else {
        lbl.text = @"You are not logged in.";
    }

}
- (void)storeAccessToken:(NSString *)accessToken {
    [[NSUserDefaults standardUserDefaults]setObject:accessToken forKey:@"SavedAccessHTTPBody"];
}

- (NSString *)loadAccessToken {
    return [[NSUserDefaults standardUserDefaults]objectForKey:@"SavedAccessHTTPBody"];
}
4.Now you are ready to get your request, with the following method(in this method I created a `Twitter` search for some `Hashtag`, to get the screen_name for example):

- (void)listResults {

    dispatch_async(GCDBackgroundThread, ^{
        @autoreleasepool {
            [UIApplication sharedApplication].networkActivityIndicatorVisible = YES;

        // the following line contains a FHSTwitterEngine method wich do the search.

            dict = [[FHSTwitterEngine sharedEngine]searchTweetsWithQuery:@"#iOS" count:100 resultType:FHSTwitterEngineResultTypeRecent unil:nil sinceID:nil maxID:nil];
          // NSLog(@"%@",dict);
            NSArray *results = [dict objectForKey:@"statuses"];

          //  NSLog(@"array text = %@",results);
            for (NSDictionary *item in results) {
                NSLog(@"text == %@",[item objectForKey:@"text"]);
                NSLog(@"name == %@",[[item objectForKey:@"user"]objectForKey:@"name"]);
                NSLog(@"screen name == %@",[[item objectForKey:@"user"]objectForKey:@"screen_name"]);
                NSLog(@"pic == %@",[[item objectForKey:@"user"]objectForKey:@"profile_image_url_https"]);
            }

            dispatch_sync(GCDMainThread, ^{
                @autoreleasepool {
                    UIAlertView *av = [[UIAlertView alloc]initWithTitle:@"Complete!" message:@"Your list of followers has been fetched" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
                    [av show];
                    [UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
                }
            });
        }
    });
}

就这样。我刚刚screen_name从 asearch Query中获得，您可以使用以下方法为用户获取时间线：

// statuses/user_timeline
- (id)getTimelineForUser:(NSString *)user isID:(BOOL)isID count:(int)count;
- (id)getTimelineForUser:(NSString *)user isID:(BOOL)isID count:(int)count sinceID:(NSString *)sinceID maxID:(NSString *)maxID;

而不是上面的搜索方法。

注意：请参阅FHSTwitterEngine.h以了解您需要使用什么方法。注意：要获取<consumer_key>和 ，<consumer_secret>您需要访问此链接到register您的应用程序Twitter。

您可能对以下库感兴趣。

https://github.com/nst/STTwitter

它是 Twitter REST API 1.1 的轻量级 Objective-C 包装器。

查看自述文件和演示项目以获取示例

这只是库拥有的众多方法之一：

- (void)getUserTimelineWithScreenName:(NSString *)screenName
                         successBlock:(void(^)(NSArray *statuses))successBlock
                           errorBlock:(void(^)(NSError *error))errorBlock;
