ios – 将一个UIButton连接到2个段

例如,当按下UIButton(标题为“next”)时,

if(condition 1) then go to screen A. else go to screen B.

我相信我的代码是正确的(我已经包括它),但问题是,在故事板视图,我可以连接一个按钮只有一个视图控制器使用segue.我该如何解决 ？

这是我使用的代码 –

-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{
        if([[segue identifier]isEqualToString:@"nextButtonID"]){
            creditCardViewController *cvc = [segue destinationViewController];
        }
        else if([[segue identifier]isEqualToString:@"next2ButtonID"]){
            depositInfoViewController *divc = [segue destinationViewController];
        }
}

-(IBAction)nextClicked{
        if([accountType isEqualToString:@"patron"]){
            [self performSegueWithIdentifier:@"nextButtonID" sender:self];
        }
        else{
            [self performSegueWithIdentifier:@"next2ButtonID" sender:self];
        }
}
