CORE ANIMATION
Core Animation is a software platform for rendering and animating graphics on iOS and MacOS. This framework allows developers to add animated elements to the application interface. Such details often determine the success of a project, both as a unique startup and if you have direct competitors. Core Animation is a part of UIKit and AppKit, respectively, without which it is impossible to create even a simple application interface.
Your app needs animation. Dynamic and especially interactive objects significantly improve the user experience. Animation attracts attention, illustrates actions, confirms their completion, and simply makes the application more lively and organic.
Core Animation is designed to make the work of programmers easier. Most of the basic drawing tasks are performed by built-in graphics tools that speed up rendering. They are also responsible for high frame rates and smooth transitions, without heavy loads on the main processor. All drawing operations will be performed in the graphics engine. To create a motion effect, you just need to set the basic animation parameters, such as the start and end points, and then tell the framework about it.
Just as Core Graphics creates 2D graphics by describing layers step by step, Core Animation works with the same model objects. By assigning them attribute values, such as borders or shadows, you can create highly complex dynamic images. Animations can be grouped together to run simultaneously or at a specified time interval, and much more.
A couple of lines of standard code are enough to draw a simple shape. Basic animation options for layers, such as motion, rotation, overlap, ripple, and so on, can also be called as a method that speeds up the work. If you want to draw something out of the ordinary, there are also all the necessary tools for this. You can create any shapes by connecting points with lines and curves, and then programmatically assign them motion patterns of varying complexity.
Core Animation is a framework without which it is impossible to create a beautiful dynamic application that is intuitive to the user. The idea of the project doesn't matter. Everyone needs page refreshing, reaction to button presses, screen transitions, and other basic animations. But if your goal is to create an app with a good UX that will make you stand out from the competition, you'll need much more. With Core Animation, you can create animations of any complexity, which by default will run smoothly at high frame rates without loading the processor.
