Understanding the Rotation Methods in UIViewController The UIViewController class provides several methods to handle rotation, including shouldAutorotateToInterfaceOrientation:, willRotateToInterfaceOrientation:duration:, willAnimateFirstHalfOfRotationToInterfaceOrientation:duration:, willAnimateSecondHalfOfRotationFromInterfaceOrientation:duration:, and didRotateFromInterfaceOrientation:. But who is responsible for dispatching these method calls? And how does the UIViewController instance know which one to respond to? The Role of UIApplication According to Apple’s documentation, it is indeed the UIApplication class that is responsible for forwarding messages related to rotation to the active view controller.

Creating a Column Based on the Substring of Another Column Using case_when In this article, we will explore how to create a new column in a data frame based on the substring of another column using the case_when function from the dplyr package.
