iOS 发布 Twitter 媒体崩溃

Question

我正在尝试将图片从我的应用程序发布到 Twitter 帐户。它在我的 3 台设备上运行良好，但在我的一位 friend 上崩溃了。我正在使用以下代码..到目前为止已经浪费了近 2 天的时间，没有任何运气。请查看问题行，根据崩溃分析，应用程序在这两行上崩溃。有人经历过这种情况吗？

NSString *account_id = [PFUser currentUser][@"Twitter_ScreenName"];

            NSURL *retweetURL = [NSURL URLWithString:@"https://api.twitter.com/1.1/statuses/update_with_media.json"];
            //Problem
            NSDictionary *params = @{@"status" : [NSString stringWithFormat:@"%@#mytag",self.postTextView.text]};
            SLRequest *request = [SLRequest requestForServiceType:SLServiceTypeTwitter
                                                    requestMethod:SLRequestMethodPOST
                                                              URL:retweetURL
                                                       parameters:params];
            NSData *imageData = UIImageJPEGRepresentation(self.postImage, 0.5f);
            [request addMultipartData:imageData withName:@"media[]" type:@"image/jpeg" filename:@"image.jpg"];

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

            [account requestAccessToAccountsWithType:accountType options:nil completion:^(BOOL granted, NSError *error)
             {
                 if (granted == YES)//Problem
                 {
                     NSArray *twitterAccounts =
                     [account accountsWithAccountType:accountType];


                     if ([twitterAccounts count] > 0)
                     {
                         ACAccount *twitterAccount;

                         for (int i=0; i<[twitterAccounts count]; i++)
                         {
                             ACAccount *acc=[twitterAccounts objectAtIndex:i];
                             if ([acc.username isEqualToString: account_id ])
                             {
                                 twitterAccount = acc;
                                 break;

                             }
                         }

Answer 1

我最终碰巧创建了一个简单的应用程序，它只使用用户的 Twitter 帐户发布媒体。我能够确定这个问题，这是因为过期的 token 。用户的 Twitter 凭据不再准确。当他在“设置”中点击他的 Twitter 帐户时，我们收到了警报来证明这一点。一旦他重新输入警报，一切就开始工作了。现在它也可以在我的主应用程序中运行。

谢谢大家!
