Login twitter IOS without go to the Settings (like instagram) -

i'm newer in twitter integration ios

so, have doubt that.

i saw in many examples on web when don't have account connected in twitter, show alert , redirect user setting login in twitter account.

how can make login form instagram? user can insert user_name , password , submit it?

my code @ moment:

accountstore = [[acaccountstore alloc] init]; acaccounttype *twittertype = [accountstore accounttypewithaccounttypeidentifier:acaccounttypeidentifiertwitter];  // request access user use twitter accounts. [accountstore requestaccesstoaccountswithtype:twittertype options:nil completion:^(bool granted, nserror *error) {       if (granted == yes){       //get accounts use.       accounts = [accountstore accountswithaccounttype:twittertype];       if ([accounts count] > 0) nslog(@"account: %@", accounts);       }else{          // show alert inser user_name , password login on twitter          alerttwitteraccount = [[uialertview alloc]                                       initwithtitle:@"enter twitter account"                                             message:nil                                            delegate:self                                   cancelbuttontitle:@"cancel"                                   otherbuttontitles:@"login", nil];          [alerttwitteraccount setalertviewstyle:uialertviewstyleloginandpasswordinput];          [[alerttwitteraccount textfieldatindex:0] setplaceholder:@"user"];          [alerttwitteraccount setdelegate:self];          [alerttwitteraccount settag:1];          [alerttwitteraccount show];       } }]; 

anyone have example or know how using slrequest or acaccount?

thanks
