根据苹果示例

，我可以使用TWRequest轻松发送推文

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

             // Build a twitter request
           TWRequest *postRequest = [[TWRequest alloc] initWithURL:
                                  [NSURL URLWithString:@"http://api.twitter.com/1/statuses/update.json"] 
                                                          parameters:[NSDictionary dictionaryWithObject:@"tweet goes here" 
                                                                                                 forKey:@"status"] requestMethod:TWRequestMethodPOST];             

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

            // Block handler to manage the response
[postRequest performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) 
              {
                  NSLog(@"Twitter response, HTTP response: %i", [urlResponse statusCode]);
              }];

但我想知道是否有可能以某种方式使用http://api.twitter.com/1/statuses/update_with_media.json来发送带有推文的图像，而不是通过twitpic或其他服务。或者是否有另一种方式将图像与推文一起发送？

有可能。您需要使用addMultiPartData：withName：type：方法为您的推文添加属性。在将其添加为多部分数据之前，不会显示状态文本。

TWRequest *postRequest = [[TWRequest alloc] initWithURL:[NSURL URLWithString:@"https://upload.twitter.com/1/statuses/update_with_media.json"] parameters:nil requestMethod:TWRequestMethodPOST];
NSData *myData = UIImagePNGRepresentation(img);
[postRequest addMultiPartData:myData withName:@"media" type:@"image/png"];
myData = [[NSString stringWithFormat:@"Any status text"] dataUsingEncoding:NSUTF8StringEncoding];
[postRequest addMultiPartData:myData withName:@"status" type:@"text/plain"];

使用TWrequest在IOS5中将带有文本的图像发送到Twitter
