Question

I’m using the following code to get the user details from Twitter in iOS 5.

if ([TWTweetComposeViewController canSendTweet]) 
{
    // Create account store, followed by a Twitter account identifer
    account = [[ACAccountStore alloc] init];
    ACAccountType *accountType = [account accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierTwitter];

    // Request access from the user to use their Twitter accounts.
    [account requestAccessToAccountsWithType:accountType withCompletionHandler:^(BOOL granted, NSError *error) 
     {
         // Did user allow us access?
         if (granted == YES)
         {
             // Populate array with all available Twitter accounts
             arrayOfAccounts = [account accountsWithAccountType:accountType];
             [arrayOfAccounts retain];

             // Populate the tableview
             if ([arrayOfAccounts count] > 0) 
                 [self performSelectorOnMainThread:@selector(updateTableview) withObject:NULL waitUntilDone:NO];
         }
     }];
}

//

-(void)updateTableview
{

    numberOfTwitterAccounts = [arrayOfAccounts count];
    NSLog(@"Twiter details-- %@",[arrayOfAccounts objectAtIndex:0]);

}

In my NSLog console, I am getting the output as follows:

Twiter details-- type:com.apple.twitter  
identifier: E8591841-2AE0-4FC3-8ED8-F286BE7A36B0
accountDescription: @Sadoo55
username: [e-mail]
objectID: x-coredata://F8059811-CFB2-4E20-BD88-F4D06A43EF11/Account/p8
enabledDataclasses: {(
)}
properties: {
  "user_id" = 308905856;
}
parentAccount: (null)
owningBundleID:com.apple.Preferences

I want to get the “user_id” from this. How can I fetch “user_id” (ie. 308905856)?

Answer 1

Getting the user ID &/or username is much easier than that.

iOS 7 version

ACAccount *account = accountsArray[0];
NSString *userID = ((NSDictionary*)[account valueForKey:@"properties"])[@"user_id"];

or

ACAccount *twitterAccount = accountsArray[0];
NSRange range = [account.description rangeOfString:@" [0-9]{7,8}"
                                           options:NSRegularExpressionSearch];
if (range.location != NSNotFound) {
  NSString *userID = [[account.description substringWithRange:range] stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
  NSLog(@"User ID: %@", userID);
}

iOS 5 version

There was an undocumented method of ACAccount called accountProperties of type NSDictionary with a user_id key.

ACAccount *twitterAccount = [accountsArray objectAtIndex:0];
NSString *userID = [[twitterAccount accountProperties] objectForKey:@"user_id"];
NSString *username = twitterAccount.username;

**Does not work under iOS6 because the method is no longer defined.
