ios - SLRequest - Twitter 返回代码 215(错误的身份验证数据)

Question

我有上传照片的应用程序，就像在 Instagram 应用程序中一样。首先我的应用上传照片并返回链接。然后在状态消息中发送链接。当我在我的 iPhone 上测试时，一切正常，但当我在另一部 iPhone 上测试时，twitter 返回代码 215 错误的身份验证数据。任何想法可能是错的？感谢回复。

- (void)tweet:(NSString *)identifier withCompletionHandler:(void (^)())completionHandler {
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) {
        if (identifier) {
            // Get the list of Twitter accounts.
            NSArray *accountsArray = [accountStore accountsWithAccountType:accountType];

            if ([accountsArray count] > 0) {
                // Grab the initial Twitter account to tweet from.
                NSURL *url = [NSURL URLWithString:@"https://api.twitter.com/1.1/statuses/update.json"];
                NSDictionary *dict = [NSDictionary dictionaryWithObject:[NSString stringWithFormat:@"Check out this great flick on BLA BLA %@", [BLA_URL stringByAppendingFormat:@"/%@/%@", @"flick", identifier]]
                                                                 forKey:@"status"];

                SLRequest *request = [SLRequest requestForServiceType:SLServiceTypeTwitter
                                                        requestMethod:SLRequestMethodPOST
                                                                  URL:url
                                                           parameters:dict];
                [request setAccount:[accountsArray lastObject]];
                [request performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) {
                    if ([urlResponse statusCode] == 200) {
                        NSLog(@"TWEEET!");

                    }
                    else { 
                        NSError *jsonError;
                        id data = [NSJSONSerialization JSONObjectWithData:responseData
                                                                  options:NSJSONReadingMutableLeaves
                                                                    error:&jsonError];

                        dispatch_async(dispatch_get_main_queue(), ^{
                            UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Twitter response"
                                                                                message:[NSString stringWithFormat:@"%d S: %d %@", [error code], [urlResponse statusCode], data]
                                                                               delegate:self
                                                                      cancelButtonTitle:@"Ok"
                                                                      otherButtonTitles:nil];
                            NSLog(@"NOOO TWEEET!");
                            [alertView show];
                            completionHandler();
                        });
                    }
                }];
...

和预检功能:

- (IBAction)twitterButtonTapped:(id)sender {
if ([self.twitterButton isSelected]) {
    [self.twitterButton setSelected:NO];
}
else {
    [self.twitterButton setSelected:YES];

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

    [accountStore requestAccessToAccountsWithType:accountType withCompletionHandler:^(BOOL granted, NSError *error) {
        if (!granted) {
            [self.twitterButton setSelected:NO];

            UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Twitter access"
                                                                message:@"Please make sure you have allowed twitter for BLA BLA in your Settings."
                                                               delegate:self
                                                      cancelButtonTitle:@"Ok"
                                                      otherButtonTitles:nil];
            [alertView performSelectorOnMainThread:@selector(show) withObject:nil waitUntilDone:NO];
        }
    }];
}

好的，我有答案了!问题是其他 iPhone 的帐户数据不完整 - 这意味着您必须在“设置”应用中填写用户名和密码。
