Titanium.UI.iOS.CoverFlowView

viewiPhoneiPadmacOSsince iPhone 0.8, iPad 0.8, macOS 9.2.0

Extends Titanium.UI.ViewTitanium.Proxy

The cover flow view is a container showing animated three-dimensional images in a style consistent with the former cover flow presentation style used for iPod, iTunes, and Finder.

The cover flow view is created by the Titanium.UI.iOS.createCoverFlowView method or <CoverFlowView> element in an Alloy application.

Examples

Simple 3 image cover flow example

Create a simple cover flow view.

var view = Titanium.UI.iOS.createCoverFlowView({
  backgroundColor:'#000',
  images:['a.png','b.png','c.png']
});
window.add(view);

Alloy XML Markup

Previous example as an Alloy view.

<Alloy>
    <Window id="window">
        <CoverFlowView id="view" platform="ios" backgroundColor="#000">

            <!-- The Images tag sets the CoverFlowView.images property. -->
            <Images>

                <!-- Assign the image by node text or the image attribute. -->
                <!-- Can also specify the width and height attributes. -->

                <Image>a.png</Image>
                <Image>b.png</Image>
                <Image>c.png</Image>

            </Images>

            <!-- Place additional views for the CoverFlowView here. -->

        </CoverFlowView>
    </Window>
</Alloy>
