您可以使用下面的代碼：（如果不考慮從設置中，那麼這將您的應用程序到設備的設置屏幕）：

- (IBAction)loginWithTwitterBtn:(id)sender 
{ 
    if ([TWTweetComposeViewController canSendTweet]) 
    { 
     //yes user is logged in 
     accountStore = [[ACAccountStore alloc] init]; 
     ACAccountType *accountType = [accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierTwitter]; 

     // Request access from the user to use their Twitter accounts. 
     [accountStore requestAccessToAccountsWithType:accountType withCompletionHandler:^(BOOL granted, NSError *error) 
     { 
      // Did user allow us access? 
      if (granted == YES) 
      { 
       // Populate array with all available Twitter accounts 
       NSArray *arrayOfAccounts = [accountStore accountsWithAccountType:accountType]; 

       ACAccount *acct = [arrayOfAccounts objectAtIndex:0]; 

       // Set the cell text to the username of the twitter account 
       NSString *userID = [[acct valueForKey:@"properties"] valueForKey:@"user_id"]; 

      } 
     }]; 
    } 
    else 
    { 
     //show tweeet login prompt to user to login 
     TWTweetComposeViewController *viewController = [[TWTweetComposeViewController alloc] init]; 

     //hide the tweet screen 
     viewController.view.hidden = YES; 

     //fire tweetComposeView to show "No Twitter Accounts" alert view on iOS5.1 
     viewController.completionHandler = ^(TWTweetComposeViewControllerResult result) { 
      if (result == TWTweetComposeViewControllerResultCancelled) { 
       [self dismissModalViewControllerAnimated:NO]; 
      } 
     }; 
     [self presentModalViewController:viewController animated:NO]; 

     //hide the keyboard 
     [viewController.view endEditing:YES]; 
    } 
}
