Dynamic UIActionSheet 'otherButtonTitles:'

Question

I am trying to create something to list all the Twitter user accounts connected to the device in UIActionSheet. For example, I have three Twitter accounts on my device. I would like the action sheet to list my accounts with a cancel button. Currently my function looks like this:

- (void)showAlertViewForAccounts:(NSArray*)accounts {
    accounts = _.arrayMap(accounts, ^id(ACAccount *account) {
        return account.username;
    });

    UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:@"Choose an account:"
                                                             delegate:self
                                                    cancelButtonTitle:@"Cancel"
                                               destructiveButtonTitle:nil
                                                    otherButtonTitles:nil];
    for (NSString *username in accounts) {
        [actionSheet addButtonWithTitle:username];
    }    


    [actionSheet showInView:[[[[[UIApplication sharedApplication] delegate] window] rootViewController] view]];
}

My problem is that the cancel button does not appear in a separate “section” of the action sheet.

In any case, I can A.) convert the array accountsto va_list, which should be passed as a parameter of the method UIActionSheet init..., or B.) indicate that the cancel button should be displayed in a separate "section"?

Answer 1

:

- (void)showAlertViewForAccounts:(NSArray*)accounts {
    accounts = _.arrayMap(accounts, ^id(ACAccount *account) {
        return account.username;
    });

    UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:@"Choose an account:"
                                                             delegate:self
                                                    cancelButtonTitle:nil
                                               destructiveButtonTitle:nil
                                                    otherButtonTitles:nil];
    for (NSString *username in accounts) {
        [actionSheet addButtonWithTitle:username];
    }    

    actionSheet.cancelButtonIndex = [actionSheet addButtonWithTitle:@"Cancel"];  

    [actionSheet showInView:[[[[[UIApplication sharedApplication] delegate] window] rootViewController] view]];
}
