UIAppearance. Manage the appearance of iOS applications
Style or Essence
Message or Media
Rhetoric or Dialectic
Is beauty something superficial or coming from deep truths?
What does “good design” mean?
Aesthetic judgments are relative or absolute?
These are important questions that have been discussed by philosophers, artists, and poets for millennia.

And while we continue our search for beauty and understanding of the world, the market for mobile applications in this area clearly states:
Users pay for beautiful applications.
When buying an iPhone, the user also buys Apple's philosophy: things must not only work well, but also look good. The same applies to the development on iOS - an ugly user interface affects the program code.
Historically, even for a minor change in the appearance of an application in iOS, a set of hacks was required, with the risk of rejecting the application in the AppStore. Fortunately, starting with iOS 5, developers have a new tool:

UIKit structure, UIKit specialists implemented a rather interesting solution: UIAppearance is a protocol that provides a proxy object that is used to configure objects of a particular class. Why proxy, but not property or method of UIView itself? Because there are objects that are not part of the UIView hierarchy, such as UIBarButtonItem , with their own view. The appearance can be changed for all components of a particular type or only for those linked to a specific hierarchy:+appearancereturns a proxy object for this class of elements.+appearanceWhenContainedIn:(Class )ContainerClass,...: - , .
.
The spirit of perfectionism is still alive in iOS. The community is constantly developing a system in the field of user interaction. This makes iOS development more difficult, but also much more enjoyable.
Do not settle for half measures.
Make your applications beautiful from appearance to implementation.
