You can download any needed medias in your app document folder.

You can get it's URL that way :

  [NSHomeDirectory() stringByAppendingPathComponent:@"Documents"]

or

NSString *homeDir = NSHomeDirectory();
NSArray *arrayPaths = 
    NSSearchPathForDirectoriesInDomains(
        NSDocumentDirectory,
        NSUserDomainMask,
        YES);

NSString *docDir = [arrayPaths objectAtIndex:0];

You could try out this answer. Basically, you store all your content in a directory. If the directory exists, do nothing. Else, download a zip file and unzip the contents into the directory. It's all detailed in the link above.
