Principle for Mac 2.1.5 介绍
Principle makes it easy to create animated and interactive user interface designs. Go beyond static mockups and create living designs that express feeling. Whether you're designing the flow of a multi-screen app, or fun new interactions and animations, Principle lets you create designs that look and feel amazing.
The familiar interface enables app designers to show their animated designs to clients, managers and the development team - gone are the days of handwaving and long meetings.
Inspired by studying how some of the world’s best user interface designers work, Principle combines the design, animation and interaction tools you need into a lightweight, easy-to-learn interface.
Principle is retina-ready and built on the same rendering and animation system that powers OS X and iOS, so you can be confident that your designs will match reality.
Interact with layers, artboards and animations, not code, so you can focus on what you do best: thinking visually. Design each state of your app, and Principle will automatically animate between them.
Interact with your ideas as soon as you have them, not after weeks of development time — on your iOS device or in Principle’s preview.
Room for Your Ideas
Principle doesn’t constrain you to pre-canned animations and transitions, so you can design experiences that are entirely new.
A Native Experience
Designed for OS X and built on Core Animation, Principle has the performance, shortcuts and power that you expect from a native app.
Export a movie, animated gif, or share the design itself to explain your ideas, track development progress, and show clients.
Note: Now requires OS X 10.10 or later.
