Attempting to save image to applicationDataDirectory

TiSDK 1.7.1 iOS 5.0

Hi all,

I'm attempting to take the URL of an image that is passed to the app and store it in applicationDataDirectory.

I've written a function that takes the url, creates an ImageView, passes it to .toImage() and then writes it to a file.

When I run it in the simulator and go to the applicationDataDirectory to view the image it's the generic placeholder image.

Thoughts?

Hi, I'am realize this with the following code: 

var cachedImageView = function(imageDirectoryName, url, imageViewObject, hires) {
    var filename = url.split('/');
    var hiresfilename;
    filename = filename[filename.length - 1];
    hiresfilename = filename.split('.');
    hiresfilename = hiresfilename[hiresfilename.length - 2] + '@2x' + hiresfilename[hiresfilename.length - 1];
    var file = Ti.Filesystem.getFile(Ti.Filesystem.applicationDataDirectory, imageDirectoryName, filename);
    var hiresfile = Ti.Filesystem.getFile(Ti.Filesystem.applicationDataDirectory, imageDirectoryName, hiresfilename);
 
    if (file.exists()) {
        imageViewObject.image = file.nativePath;
    } else {
        var g = Ti.Filesystem.getFile(Ti.Filesystem.applicationDataDirectory, imageDirectoryName);
        if (!g.exists()) {
            g.createDirectory();
    };
    var xhr = Ti.Network.createHTTPClient();
    xhr.onload = function() {
        if (xhr.status == 200) {
            file.write(xhr.responseData);
            if (hires) {
                hiresfile.write(xhr.responseData);
            }   
            imageViewObject.image = file.nativePath;
        };
    };
    xhr.open('GET', url);
    xhr.send();
};
This code realizes also hires images.
