如何在肖像和风景上制作UITableView不同的colume？

Question

I need to present table view on iOS universal app (iPhone/iPad). I'm seeking a simple way to make different column on portrait and landscape

My target

iPhone portrait has 3 labels
iPad portrait has 6 labels
iPhone&iPad landscape has 6 labels

I should be programatically or use size classes or the other way ?

Please explain to me.

Thank you

Answer 1

1) [[UIDevice current] userInterfaceIdiom] for determine iPhone or iPad

2) [[UIApplication sharedApplication] statusBarOrientation] for determine current orientation

And via UIApplicationDelegate get events

- (void)application:(UIApplication *)application willChangeStatusBarOrientation:(UIInterfaceOrientation)newStatusBarOrientation duration:(NSTimeInterval)duration;
- (void)application:(UIApplication *)application didChangeStatusBarOrientation:(UIInterfaceOrientation)oldStatusBarOrientation;

Or you can subscribe on notifications in NSNotificationCenter

UIApplicationWillChangeStatusBarOrientationNotification; 
UIApplicationDidChangeStatusBarOrientationNotification; 
UIApplicationStatusBarOrientationUserInfoKey;
