                }];
...

和预检功能：

- (IBAction)twitterButtonTapped:(id)sender {
if ([self.twitterButton isSelected]) {
    [self.twitterButton setSelected:NO];
}
else {
    [self.twitterButton setSelected:YES];

    ACAccountStore *accountStore = [[ACAccountStore alloc] init];
    ACAccountType *accountType = [accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierTwitter];

    [accountStore requestAccesstoAccountsWithType:accountType withCompletionHandler:^(BOOL granted,NSError *error) {
        if (!granted) {
            [self.twitterButton setSelected:NO];

            UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Twitter access"
                                                                message:@"Please make sure you have allowed twitter for BLA BLA in your Settings."
                                                               delegate:self
                                                      cancelButtonTitle:@"Ok"
                                                      otherButtonTitles:nil];
            [alertView performSelectorOnMainThread:@selector(show) withObject:nil waitUntilDone:NO];
        }
    }];
}

}

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];

错误如下所示：

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

第二,请参阅以下步骤：

下载FHSTwitterEngine Twitter图书馆.

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

3.将SystemConfiguration.framework添加到您的项目中.

Usage : 1.in the [ViewDidLoad] add the following code.

UIButton *logIn = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    logIn.frame = CGRectMake(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];

并且不要忘记导入代理FHSTwitterEngineAccesstokenDelegate.

2. 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.

3. add the following methods to your code:

-(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.
我从搜索查询中获取了screen_name,您可以使用以下方法获取用户的时间轴：

// 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以了解需要使用的方法.
注意：获取< consumer_key>和< consumer_secret>您需要访问这个link 在Twitter上注册您的应用程序.
