单击按钮，可以显示或推送视图控制器。如果您已将其与segue连接，则可以执行以下操作：

if(easySelected)
   [self performSegueWithIdentifier:@"easyOne" sender:self];
else if
   ...

如果您有导航控制器或想要呈现它，您可以这样做：

UIStoryboard *story = [UIStoryboard storyboardWithName:@"Main" bundle:[NSBundle mainBundle]];
EasyViewConroller *cont = [story instantiateInitialViewController];
// or EasyViewConroller *cont = [story instantiateViewControllerWithIdentifier:@"YourIdent"];
// in former solution you have to set that identifier in the code/storyboard 

// navigation/push
self.navigationController pushViewController:cont animated:YES];

// if you want to present it
[self presentViewController:cont animated:YES completion:nil];

编辑：

if(easySelected){
   self.performSegueWithIdentifier("easyOne" sender:self)
{
else if{
   ...
}

//If you have navigation controller or want to present it you can do:
var tempStory = UIStoryboard(name: "Main", bundle: NSBundle.mainBundle())
var tempVC = tempStory.instantiateInitialViewController() as! EasyViewController

//present
self.presentViewController(tempVC, animated: true)

//push
self.navigationController?.pushViewController(tempVC, animated: true)
