如何在肖像和风景上制作UITableView不同的音量？

Question

我需要在iOS通用应用程序（iPhone / iPad）上呈现表格视图。我正在寻找一种简单的方法来在肖像和风景上制作不同的专栏

我的目标

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

我应该以编程方式或使用大小类或其他方式？

请向我解释。

谢谢

Answer 1

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

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

通过UIApplicationDelegate获取事件

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

或者您可以订阅NSNotificationCenter中的通知

UIApplicationWillChangeStatusBarOrientationNotification; 
UIApplicationDidChangeStatusBarOrientationNotification; 
UIApplicationStatusBarOrientationUserInfoKey;
