iOS:如何从Twitter API 1.1获取tweet

Question

Twitter已经弃用了它的API 1.0并实现了新的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

Answer 1

首先，您需要Authenticate您的请求(获得许可)。

第二步，参照以下步骤:

1。下载FHSTwitterEngine Twitter库

2。添加文件夹FHSTwitterEngine "到您的项目和#import "FHSTwitterEngine.h".

3。添加SystemConfiguration.framework到你的项目

用法:1。在[ViewDidLoad]中添加以下代码:

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!!!");
    }];
}

当登录窗口出现时，输入您的Twitter用户名和密码来验证您的请求。

在代码中添加以下方法:

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

。我刚刚从search Query中获得了screen_name，您可以使用以下方法获得用户的时间轴:

// 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以了解您需要使用的方法。注意:要获得<consumer_key>和<consumer_secret>，您需要访问register的链接，你的应用程序在Twitter。

您可能对下面的库感兴趣。

https://github.com/nst/STTwitter

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

查看ReadMe和Demo项目中的示例

这只是库中众多方法之一:

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