Iphone twitter.framework问题

我正在尝试在iOS 5上使用twitter实现单点登录，除了在settings.app中没有帐户时，应用程序会陷入无限循环，控制台上会显示此消息“twitter会话中断，重新启动。”

应用程序冻结在这行代码上

if ([TWTweetComposeViewController canSendTweet])

非常感谢您的帮助

///EDIT//// 这是我的密码 if（[TWTweetComposeViewController canSendTweet]） { ACAccountStore*accountStore=[[ACAccountStore alloc]init]

// Create an account type that ensures Twitter accounts are retrieved.
ACAccountType *accountType = [accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierTwitter];

// Request access from the user to use their Twitter accounts.
[accountStore requestAccessToAccountsWithType:accountType withCompletionHandler:^(BOOL granted, NSError *error) {
    if(granted) {
        // Get the list of Twitter accounts.
        NSArray *accountsArray = [accountStore accountsWithAccountType:accountType];

        // For the sake of brevity, we'll assume there is only one Twitter account present.
        // You would ideally ask the user which account they want to tweet from, if there is more than one Twitter account present.
        if ([accountsArray count] > 0)
        {
            // Grab the initial Twitter account to tweet from.
            ACAccount *twitterAccount = [accountsArray objectAtIndex:0];


            NSURL *url = [NSURL URLWithString:@"http://api.twitter.com/1/account/verify_credentials.json"];
            TWRequest *req = [[TWRequest alloc] initWithURL:url
                                                 parameters:nil
                                              requestMethod:TWRequestMethodGET];

            // Important: attach the user's Twitter ACAccount object to the request
            req.account = twitterAccount;

            [req performRequestWithHandler:^(NSData *responseData,
                                             NSHTTPURLResponse *urlResponse,
                                             NSError *error) {

                // If there was an error making the request, display a message to the user
                if(error != nil) {

                }

                // Parse the JSON response
                NSError *jsonError = nil;
                id resp = [NSJSONSerialization JSONObjectWithData:responseData
                                                          options:0
                                                            error:&jsonError];

                // If there was an error decoding the JSON, display a message to the user
                if(jsonError != nil) {

                    return;
                }




            }];


        }
    }
}];
 }

使用此代码检查Twitter帐户是否存在：-

if ([TWRequest class])
            {
            ACAccountStore *as = [[ACAccountStore alloc] init];
            ACAccountType *accountType = [as accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierTwitter];
            NSArray *twitterAccounts = [as accountsWithAccountType:accountType];
            if (!twitterAccounts.count)
            {
                NSLog(@"No Twitter Account configured");

            }
            }

希望它能对您有所帮助！

非常感谢，但我以前也尝试过。当我使用accounts中的类时，它会卡住。framework…在您的代码中，应用程序在ACAccountStore*上冻结为=[[ACAccountStore alloc]init]；您是在模拟器还是在设备上测试它？我在设备和模拟器上都遇到了相同的问题。我添加了我的代码作为问题的编辑
