TwUI is a hardware accelerated UI framework for Mac, inspired by UIKit. It enables:
It differs from UIKit in a few ways:
To use the current development version, include all the files in your project and import TUIKit.h. Set your target to link to the ApplicationServices and QuartzCore frameworks.
TUIView-based view hierarchy is hosted inside an
TUINSView, which is the bridge between AppKit and TwUI. You may set a
TUINSView as the content view of your window, if you'd like to build your whole UI with TwUI. Or you may opt to have a few smaller
TUINSViews, using TwUI just where it makes sense and continue to use AppKit everywhere else.
You can also add
NSViews to a TwUI hierarchy using
TUIViewNSViewContainer, which bridges back into AppKit from TwUI.
An included example project shows off the basic construction of a pure TwUI-based app. A
TUINSView is added as the content view of the window, and some
TUIView-based views are hosted in that. Within the table view cells, some
NSTextFields are also added using
TUIViewNSViewContainer. It includes a table view and a tab bar (which is a good example of how you might build your own custom controls).
TwUI is currently shipping in Twitter for Mac and GitHub for Mac, in use 24/7 by many, many users, and has proven itself very stable.
This project follows the SemVer standard. The API may change in backwards-incompatible ways between major releases.
The goal of TwUI is to build a high-quality UI framework designed specifically for the Mac. Much inspiration comes from UIKit, but diverging to try new things (i.e. block-based layout and drawRect), and optimizing for Mac-specific interactions is encouraged.
