Where to download images to in xcode

I was working with an xcode project(game with cocos2d) that uses a lot of sprites. The thing is I would want to download images from the URL to a local directory on the device, so that i can use them later to create sprites.

So what would be the best location to download the images to? I can create a folder reference inside my projects folder, but is that a good way to go about it? Is there a standard practice to this?

I read that there are iphone which can be used for this? Please let me know if there are resources that can help me understand these better....

Thanx

You can download all images form the URl to DocumentDirectory and you can use it later, as a part of your game. I am using the following code to download Images

NSArray* path = NSSearchPathForDirectoriesInDomains(NSDocumentationDirectory, NSUserDomainMask, YES);
NSString* docPath = [path objectAtIndex:0];
        docPath = [docPath stringByAppendingPathComponent:@"ImageName.png"];
UIImage* image = [UIImage imageWithData:[NSData dataWithContentsOfURL:[NSURL URLWithString:[[array objectAtIndex:o] valueForKey:@"Image_Question"]]]];
NSData* imgData = UIImagePNGRepresentation(image);
[imgData writeToFile:docPath atomically:YES];

And when you want to retrieve for any usage in application you can use the following code

UIImage* imageFormDoc = [UIImage imageWithContentsOfFile:docPath];

and when you want to delete the image form the Document Directory you can use the following code.

[[NSFileManager defaultManager] removeItemAtPath:docPath error: &error];

docPath is the full path of Document Directory with Image then you can Print Using NSLog for detail information.emphasized text
