我遇到了同样的问题，错误代码为 220.在我的情况下修复是提示用户再次输入其 Twitter 密码.

I experienced same issue with getting error code 220. Fix in my case was to prompt user to enter it's Twitter password again.

检查下面的示例代码:

SLRequest *request = [SLRequest requestForServiceType:SLServiceTypeTwitter
                                            requestMethod:SLRequestMethodPOST
                                                      URL:[NSURL URLWithString:@"https://api.twitter.com/1.1/statuses/update.json"]
                                               parameters:@{@"status": tweetString}];

[request setAccount:account];  
[request performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) {

   if ([responseData isKindOfClass:[NSData class]]) {

       NSError *jsonError = nil;
       NSDictionary *json = [NSJSONSerialization JSONObjectWithData:responseData options:0 error:&jsonError];

       if (json) {
           NSArray *errors = json[@"errors"];
           if (errors.count) {

               NSUInteger errorCode = [json[@"errors"][0][@"code"] integerValue];
                   if (errorCode == 220) {

                       ACAccountStore *accountStore = [[ACAccountStore alloc] init];
                       [accountStore renewCredentialsForAccount:account completion:^(ACAccountCredentialRenewResult renewResult, NSError *error2) {
                            NSLog(@"Renew result: %ld, error: %@", (long)renewResult, error2);

                            if (renewResult == ACAccountCredentialRenewResultRenewed) {
                                [self __makeTweetWithAccounts:@[account] rating:rating review:review];
                             }
                        }];
                }
            }
        }
    }             
    NSLog(@"Twitter response data: %@", [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding]);
}];
