推文，不使用推文表 [英] Tweet, without using the tweet sheet

问题描述

我正在使用以下代码通过twitter分享内容（来自 UITextView ， UIImageView ）

I'm using below code to share the content (from UITextView, UIImageView) through twitter

-(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，没有使用弹出视图（我认为推文表）。这是因为下面的代码，

But I need share this, without using the pop up view (I think tweet sheet). It's happening because the below code,

[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Twitter上发布。

When I click the button "Share" of my app, I need to post that in twitter.

- (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"];

         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

                      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];
}

推荐答案

要发送图像，您需要做类似的事情

To send images u need do something like this

  [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
