我正在使用下面的代码通过 twitter分享内容（来自UITextView, ）UIImageView

-(void)shareViaTweet:(NSString *)shareMessage{
if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeTwitter])
{
    SLComposeViewController *tweetSheet = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeTwitter];
    [tweetSheet setInitialText:[NSString stringWithFormat:@"%@",shareMessage]];
    if (self.imageString)
    {
        [tweetSheet addImage:[UIImage imageNamed:self.imageString]];
    }

    if (self.urlString)
    {
        [tweetSheet addURL:[NSURL URLWithString:self.urlString]];
    }
    [self presentViewController:tweetSheet animated:YES completion:nil];
}
else
{
    UIAlertView *alertView = [[UIAlertView alloc]
                              initWithTitle:@"Sorry"
                              message:@"You can't send a tweet right now, make sure your device has an internet connection and you have at least one Twitter account setup"
                              delegate:self
                              cancelButtonTitle:@"OK"
                              otherButtonTitles:nil];
    [alertView show];
}

}

但我需要分享这个，而不使用弹出视图（我认为是推特表）。发生这种情况是因为下面的代码，

[self presentViewController:tweetSheet animated:YES completion:nil];

当我点击我的应用程序的“分享”按钮时，我需要在推特上发布。

编辑：

- (IBAction)doneButtonClicked:(id)sender
{
ACAccountStore *account = [[ACAccountStore alloc] init];
ACAccountType *accountType = [account accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierTwitter];
NSString *message = messageTextView.text;
//hear before posting u can allow user to select the account
NSArray *arrayOfAccons = [account accountsWithAccountType:accountType];
for(ACAccount *acc in arrayOfAccons)
{
    NSLog(@"%@",acc.username); //in this u can get all accounts user names provide some UI for user to select,such as UITableview
}


NSURL *url = [NSURL URLWithString:@"https://api.twitter.com"
              @"/1.1/statuses/user_timeline.json"];
             NSDictionary *params = @{@"screen_name" : message,
                                     @"forKey":@"status",
                                      @"trim_user" : @"1",
                                      @"count" : @"1"};
// Request access from the user to access their Twitter account

[account requestAccessToAccountsWithType:accountType options:nil completion:^(BOOL granted, NSError *error)

 {
     if (granted == YES)
     {
         // Populate array with all available Twitter accounts
         NSArray *arrayOfAccounts = [account accountsWithAccountType:accountType];
         if ([arrayOfAccounts count] > 0)
         {
             //use the first account available
             ACAccount *acct = [arrayOfAccounts objectAtIndex:0]; //hear this line replace with selected account. than post it :)




             SLRequest *request =
             [SLRequest requestForServiceType:SLServiceTypeTwitter
                                requestMethod:SLRequestMethodPOST
                                          URL:url
                                   parameters:params];


             //Post the request
             [request setAccount:acct];

             //manage the response
             [request performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error)
              {
                  if(error)
                  {
                      //if there is an error while posting the tweet
                      UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Twitter" message:@"Error in posting" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
                      [alert show];

                  }
                  else
                  {
                      // on successful posting the tweet
                      NSLog(@"Twitter response, HTTP response: %i", [urlResponse statusCode]);
                      UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Twitter" message:@"Successfully posted" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
                      [alert show];


                  }
              }];

         }
         else

             UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Twitter" message:@"You have no twitter account" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
             [alert show];

         }
     }
     else
     {
         //suppose user not set any of the accounts
         UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Twitter" message:@"Permission not granted" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
         [alert show];

     }
 } ];


//[widgetsHandler closeWidget:nil];


//[self postImage:shareImageView.image withStatus:messageTextView.text];
}

要发送图像，您需要执行以下操作


  [account requestAccessToAccountsWithType:accountType withCompletionHandler:^(BOOL granted, NSError *error)
 {
   if (granted == YES)
    {
      // Populate array with all available Twitter accounts
     NSArray *arrayOfAccounts = [account accountsWithAccountType:accountType];
     if ([arrayOfAccounts count] > 0)
      {
           //use the first account available
       ACAccount *acct = [arrayOfAccounts objectAtIndex:0];

       //create this request 
       SLRequest *postRequest = [SLRequest requestForServiceType:SLServiceTypeTwitter requestMethod:SLRequestMethodPOST URL:[NSURL   URLWithString:@"https://api.twitter.com"@"/1.1/statuses/update_with_media.json"] parameters:  [NSDictionary dictionaryWithObject:message forKey:@"status"]];
       UIImage *imageToPost = [UIImage imageNamed:@"image.jpg"];
       NSData *imageData = UIImageJPEGRepresentation(imageToPost, 1.0f);//set the compression quality
      [postRequest addMultipartData:imageData withName:@"media" type:@"image/jpeg" filename:@"image.jpg"];

   //set account and same as above code 

....
 ....

如果您想在不使用推文表的情况下分享推文，请参阅我的答案，它将在推特墙上发布，而不使用推文表，请参阅收听，并在设备中设置推特帐户。希望这可以帮助

不幸的是，该类TWRequest在 iOS 6 中已弃用，但我们也可以SLRequest在 Social 框架中使用 present

这个答案类似于旧答案我注释掉了我不想要的东西但是如果你想选择使用哪个帐户然后取消注释注释代码


 - (IBAction)doneButtonClicked:(id)sender
    {
      ACAccountStore *account = [[ACAccountStore alloc] init];
      ACAccountType *accountType = [account accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierTwitter];
      NSString *message = _textView.text;

    //    NSArray *arrayOfAccons = [account accountsWithAccountType:accountType];
    //    for(ACAccount *acc in arrayOfAccons)
    //    {
    //        NSLog(@"%@",acc.username);
    //        NSDictionary *properties = [acc dictionaryWithValuesForKeys:[NSArray arrayWithObject:@"properties"]];
    //        NSDictionary *details = [properties objectForKey:@"properties"];
    //        NSLog(@"user name = %@",[details objectForKey:@"fullName"]);
    //        NSLog(@"user_id  =  %@",[details objectForKey:@"user_id"]);
    //    }


    // Request access from the user to access their Twitter account
    [account requestAccessToAccountsWithType:accountType withCompletionHandler:^(BOOL granted, NSError *error)

[account release];
