ionic-ion-imageCacheFactory

A factory to preload images for your Ionic app.

Usage

First, import the script into your page.

<script src="https://github.com/andrewmcgivery/ionic-ion-imageCacheFactory/raw/v1.0.2/lib/ionic.ion.imagecachefactory.js">
</script>

Next, import the module into your app.

angular.module('myCoolApp', ['ionic','ionic.ion.imageCacheFactory'])

Finally, you can call the factory by passing it an array of image URLs to preload.

$ImageCacheFactory.Cache([
        "http://domain.com/path/to/kittens.jpg",
        "http://domain.com/path/to/kittens2.jpg",
        "http://domain.com/path/to/kittens3.jpg"
    ]);

The Cache method retuns a promise when all images have been loaded.

$ImageCacheFactory.Cache([
        "http://domain.com/path/to/kittens.jpg",
        "http://domain.com/path/to/kittens2.jpg",
        "http://domain.com/path/to/kittens3.jpg"
    ]).then(function(){
        console.log("Images done loading!");
    });

If any of the images result in an error, you can handle that as well by passing a second function to your then.

$ImageCacheFactory.Cache([
        "http://domain.com/path/to/kittens.jpg",
        "http://domain.com/path/to/kittens2.jpg",
        "http://domain.com/path/to/kittens3.jpg"
    ]).then(function(){
        console.log("Images done loading!");
    },function(failed){
        console.log("An image failed: "+failed);
    });
