Answer 1

use this methods to get the userinfo
- (void) storeCachedTwitterOAuthData: (NSString *) data forUsername: (NSString *) username
{
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setObject: data forKey: #"authData"];
[defaults synchronize];
}
- (NSString *) cachedTwitterOAuthDataForUsername: (NSString *) username
{
return [[NSUserDefaults standardUserDefaults] objectForKey: #"authData"];
}
and also
- (void)userInfoReceived:(NSArray *)userInfo forRequest:(NSString *)connectionIdentifier
{
NSLog(#"User Info Received: %#", userInfo);
}
we will get the username here

in the TWTweetComposeViewController you can get a picker shown in image and you can select one of your account from it.
when you are tweeting directly , with the help of ACAccount you can get it by
+ (void)pritnUserName {
// Create an account store object.
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) {
// Get the list of Twitter accounts.
NSArray *accountsArray = [accountStore accountsWithAccountType:accountType];
// For the sake of brevity, we'll assume there is only one Twitter account present.
// You would ideally ask the user which account they want to tweet from, if there is more than one Twitter account present.
if ([accountsArray count] > 0) {
// Grab the initial Twitter account to tweet from.
for (int i = 0 ; i < [accountsArray count] ;i++){
ACAccount *twitterAccount = [accountsArray objectAtIndex:i];
NSLog(#"username :%d is %#",i+1,twitterAccount.username);
}
}
}
}];
[accountStore release];
}
