Download image from url in ios phonegap - iphone

Question

I am trying to download an image from a url and was not successful in ios but in android it was succesfully done.
var url = "http://www.intelligrape.com/images/logo.png"; // image url
try{
window.requestFileSystem(LocalFileSystem.PERSISTENT, 0, function (fs) {
var imagePath = fs.root.fullPath + "/logo.png"; // full file path
var fileTransfer = new FileTransfer();
fileTransfer.download(url, imagePath, function (entry) {
alert(entry.fullPath); // entry is fileEntry object
}, function (error) {
alert("Some error");
});
})
}catch(e){
alert(e);
}
