ios5 - iOS 的 twitter 框架支持自动分享吗？

Question

我有一个名为 twitter 的按钮，当我通常单击此按钮时，会显示一个用于发送推文的 View ，即 TWTweetComposeViewController .我有两种发推文的方式，即自动分享和正常分享。正常分享工作得很好，但我怀疑如何在自动分享中做同样的事情，这意味着当我点击推特按钮而不是显示时会自动推特一些默认消息TWTweetComposeViewController查看并单击完成按钮。

最后我在 ios5 中搜索了很多与 Twitter 相关的问题，并在 twitter Developer Document 中阅读并尝试了这个答案。我认为这是进行自动共享的解决方案之一。

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

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

                // Sanity check
                if ([arrayOfAccounts count] > 0) 
                {
                    // Keep it simple, use the first account available
                    ACAccount *acct = [arrayOfAccounts objectAtIndex:0];

                    NSURL *url = 
                    [NSURL URLWithString:
                     @"https://upload.twitter.com/1/statuses/update_with_media.json"];

                    //  Create a POST request for the target endpoint
                    TWRequest *request = 
                    [[TWRequest alloc] initWithURL:url 
                                        parameters:nil 
                                     requestMethod:TWRequestMethodPOST];

                    //  self.accounts is an array of all available accounts; 
                    //  we use the first one for simplicity
                    [request setAccount:acct];

                    //  The "larry.png" is an image that we have locally
                    UIImage *image = (UIImage *)[dictionarydata valueForKey:@"image"];
                    NSLog(@"%@",image);
                    if (image!=nil) {

                        //  Obtain NSData from the UIImage 
                        NSData *imageData = UIImagePNGRepresentation(image);


                        //  Add the data of the image with the 
                        //  correct parameter name, "media[]"
                        [request addMultiPartData:imageData 
                                         withName:@"media[]" 
                                             type:@"multipart/form-data"];

                        // NB: Our status must be passed as part of the multipart form data
                        NSString *status = [NSString stringWithFormat:@"%@ %@ %@",[dictionaryData valueForKey:@"firstname"],[dictionaryData valueForKey:@"lastname"],[dictionarydata valueForKey:@"title"]];

                        //  Add the data of the status as parameter "status"
                        [request addMultiPartData:[status dataUsingEncoding:NSUTF8StringEncoding] 
                                         withName:@"status"

                        //  Perform the request.  
                        //    Note that -[performRequestWithHandler] may be called on any thread,
                        //    so you should explicitly dispatch any UI operations to the main thread

                         }];
