iOS：如何從Twitter API 1.1獲取推文

Question

Twitter已棄用其API 1.0並實施了新的API 1.1根據新的API，我們需要在獲取公共時間線之前進行身份驗證。

我在這里閱讀了新的API文檔： https ： //dev.twitter.com/docs/api/1.1但我不明白，如何在iOS中實現它。

任何人都可以告訴我使用API​​ 1.1獲取Twitter的公共時間表形式的最佳方式

提前致謝。

Answer 1

首先，您需要Authenticate您的請求（獲取權限）。

第二，請參閱以下步驟：

1.下載FHSTwitterEngine Twitter庫。

2.將文件夾FHSTwitterEngine “添加到您的項目和#import "FHSTwitterEngine.h".

3.add SystemConfiguration.framework到您的項目。

用法：1。在[ViewDidLoad]添加以下代碼。

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!!!");
    }];
}

顯示“登錄”窗口時，輸入您的Twitter用戶名和密碼以驗證您的請求。

將以下方法添加到您的代碼中：

-(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;
                }
            });
        }
    });
}

就這樣。 我剛剛從search Query中獲取了screen_name ，您可以使用以下方法為用戶獲取時間軸：

// 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：請參閱FHSTwitterEngine.h以了解您需要使用的方法。 注意：要獲取<consumer_key>和<consumer_secret>您需要訪問此鏈接以在Twitter register您的應用程序。

您可能對以下庫感興趣。

https://github.com/nst/STTwitter

它是Twitter REST API 1.1的輕量級Objective-C包裝器。

查看自述文件和演示項目的示例

這只是圖書館擁有的眾多方法之一：

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