It uses Core Graphics and Core Image APIs for the transition effects to animate the window / view, which probably needs a minimum of Mac OS X Tiger. The full source code is available.

Transitions Demonstration

Demonstration of the various effects available using Core Graphics and Core Image.

Usage

As easy as

1. Download the package.
2. In Xcode, open AnimatingTabsDemo.xcodeproj, then click build and run, or press Command + R. The Application will build, and the demo will run!
3. Run through the demo and play around with all the different transitions you can use!

After you’ve built it once, you can simply run the “Transitions Demo.app” package that is created in the “build” folder by double-clicking it without going through the prior steps again.

Real World Usage

When using the NSTabView subclass, you can change the default transition by setting transitionsStyle to one of the following. (Hover your mouse over for a description)

• CGNone
• CGFade
• CGZoom
• CGReveal
• CGSlide
• CGWarpFade
• CGSwap
• CGCube
• CGWarpSwitch
• CICopyMachine
• CIDisintegrate
• CIDissolve
• CIFlash
• CIMod
• CIPageCurl
• CIRipple
• CISwipe

For example, in the AnimatingTabView’s awakeFromNib: method, the following code sets the transition style to a cube effect:

transitionStyle = CGCube;

If you’re not in the AnimatingTabView’s implementation, you can use the - setTransitionStyle method. The following code sets the transition style to a ripple effect:

[AnimTabView setTransitionStyle:CIRipple];

where AnimTabView is the outlet to the AnimatingTabView

You can also get the current transition style by using the `-transitionStyle` method on the AnimatingTabView.

Transitions starting with “CG” are Core Graphics transitions and the result in the whole window being animated, while those starting with “CI” are Core Image transitions and only animate the tab view rather than the whole window.
