Titanium.UI.iOS.TransitionAnimation

In this example, the red window opens with a transition animation, while closing it uses the default behavior where it slides off screen. To add a transition animation when the red window closes, define a transition animation for the blue window.

var transition = Ti.UI.iOS.createTransitionAnimation({
    duration: 300,
    // The show transition makes the window opaque and rotates it correctly
    transitionTo: {
        opacity: 1,
        duration: 300,
        transform: Ti.UI.createMatrix2D()
    },
    // The hide transition makes the window transparent and rotates it upside down
    transitionFrom: {
        opacity: 0,
        duration: 300 / 2,
        transform: Ti.UI.createMatrix2D().rotate(180),
    }
});

var win2 = Ti.UI.createWindow({
    backgroundColor: 'red',
    title: 'Red Window',
    transitionAnimation: transition,
    opacity: 0,
    transform: Ti.UI.createMatrix2D().rotate(180)
});
var button2 = Ti.UI.createButton({
    title: 'Close Red Window'
});
button2.addEventListener('click', function(){
    nav.closeWindow(win2);
    // In order to see the blue window again,
    // need to reverse the transition animation
    win1.opacity = 1;
    win1.transform = Ti.UI.createMatrix2D().rotate(0);
});
win2.add(button2);

var win1 = Ti.UI.createWindow({
    backgroundColor: 'blue',
    title: 'Blue Window',
    // Uncomment to use a transition animation when the blue window is closed
    // transitionAnimation: transition
});
var button1 = Ti.UI.createButton({title: 'Open Red Window'});
button1.addEventListener('click', function(){
    nav.openWindow(win2);
});
win1.add(button1);

var nav = Ti.UI.createNavigationWindow({
    window: win1
});
nav.open();
