Twitter上的SLRequest给我这样的:HTTP响应状态:403错误0错误(null)

Question

我正在使用Twitter的SLRequest,直到几天前一切正常,下面的代码,但现在响应是空的,错误描述为空,这是我总是使用的代码:

ACAccountStore *accountStoreTw = [[ACAccountStore alloc] init];

ACAccountType *accountTypeTw = [accountStoreTw accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierTwitter];
[accountStoreTw requestAccessToAccountsWithType:accountTypeTw options:NULL completion:^(BOOL granted, NSError *error) {
    if(granted) {

        FMDatabase *db = [FMDatabase databaseWithPath:[self databasePath]];

        if ([db open]) {
            FMResultSet *tw_name_q = [db executeQuery:@"SELECT tw_username FROM settings WHERE id = 1"];

            NSString *tw_name = @"";

            while ([tw_name_q next]) {
                tw_name = [tw_name_q stringForColumn:@"tw_username"];
            }

            if (![tw_name isEqualToString:@""]) {

                NSArray *accountsArray = [accountStoreTw accountsWithAccountType:accountTypeTw];

                for (ACAccount *tw_account in accountsArray) {

                    if ([[tw_account username] isEqualToString:tw_name]) {

                        SLRequest* twitterRequest = [SLRequest requestForServiceType:SLServiceTypeTwitter
                                                                       requestMethod:SLRequestMethodPOST
                                                                                 URL:[NSURL URLWithString:@"http://api.twitter.com/1/statuses/update.json"]
                                                                          parameters:[NSDictionary dictionaryWithObject:msg_post forKey:@"status"]];

                        [twitterRequest setAccount:tw_account];

                        [twitterRequest performRequestWithHandler:^(NSData* responseData, NSHTTPURLResponse* urlResponse, NSError* error) {
                            NSLog(@"text response: %@", [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding]);
                            NSLog(@"error: %@",error.localizedDescription);
                            NSString *output = [NSString stringWithFormat:@"HTTP response status: %i Error %d", [urlResponse statusCode],error.code];
                            NSLog(@"%@ error %@", output,error.description);

                        }];

                        break;
                    }
                }
            }
        }

        [db close];
    }

}];

现在这个日志给我这个:

text response: 
error: (null)
403 Error 0 error (null)

问题是什么？有什么想法来解决它吗？

一直有最近改变Twitter的API.您现在只能使用HTTPS调用它.

您应确保您/您的库所使用的URL始于

https://api.twitter.com/1.1/

(注意额外s的http.)
