我使用了 twitter 提供的 twitter api,获取详细信息但无法执行,甚至尝试传递消费者密钥、消费者密钥、令牌等身份验证数据,但结果相同。
我能够登录并接收 Twitter 身份验证令牌,但无法获取用户详细信息。下面的代码是我使用的(我正在使用 MGtwitter 引擎):

NSMutableURLRequest *request =[[NSMutableURLRequest alloc]initWithURL:[NSURL URLWithString:[NSString stringWithFormat:@"https://api.twitter.com/1.1/users/show.json?screen_name=%@",username]]];

NSData *returnData = [ NSURLConnection sendSynchronousRequest: request returningResponse: nil error: nil ];

NSString *returnString = [[NSString alloc]initWithData:returnData encoding:NSUTF8StringEncoding];
    NSError *err = nil;

twitterLogin = [NSJSONSerialization JSONObjectWithData:[returnString dataUsingEncoding:NSUTF8StringEncoding] options:NSJSONReadingMutableContainers error:&err];

错误如下图所示:

errors = (
{
    code = 215;
    message = "Bad Authentication data";
} );

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 Twitter库。

2.将文件夹FHSTwitterEngine“添加到您的项目和#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];

并且不要忘记导入委托FHSTwitterEngineAccessTokenDelegate

  1. 您需要获得您的请求的权限,使用以下方法将显示登录窗口:
- (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 TwitterUsernamePasswordauthenticate的请求。

  1. 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.现在您已准备好使用以下方法获取您的请求(在此方法中,我创建了Twitter一些搜索Hashtag,以获取screen_name示例):

- (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。我刚刚从搜索查询中获得了 screen_name,您可以使用以下方法获取用户的时间线:

// 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><consumer_secret>您需要访问此链接 以在 Twitter 中注册您的应用程序。

在 MKAlatrash 还原后得到解决方案,要获取用户配置文件,请按照以下代码中的某些步骤操作:

[[FHSTwitterEngine sharedEngine]getProfileImageForUsername:username andSize:FHSTwitterEngineImageSizeNormal];

跳转到该函数的定义并替换 if ... else if 部分

if ([userShowReturn isKindOfClass:[NSError class]]) {
        return [NSError errorWithDomain:[(NSError *)userShowReturn domain] code:[(NSError *)userShowReturn code] userInfo:[NSDictionary dictionaryWithObject:request forKey:@"request"]];
        NSLog(@"user show return %@",userShowReturn);
    } else if ([userShowReturn isKindOfClass:[NSDictionary class]]) {
        return userShowReturn;
        NSString *url = [userShowReturn objectForKey:@"profile_image_url"]; // normal

        if (size == 0) { // mini
            url = [url stringByReplacingOccurrencesOfString:@"_normal" withString:@"_mini"];
        } else if (size == 2) { // bigger
            url = [url stringByReplacingOccurrencesOfString:@"_normal" withString:@"_bigger"];
        } else if (size == 3) { // original
            url = [url stringByReplacingOccurrencesOfString:@"_normal" withString:@""];
        }

        id ret = [self sendRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:url]]];

        if ([ret isKindOfClass:[NSData class]]) {
            return [UIImage imageWithData:(NSData *)ret];
        }

        return ret;
    }

这真的很有帮助谢谢
