What's wrong with my copy here?

Question

I'm trying to copy a file from my application bundle to my app's documents directory. I'm getting an error, "Cocoa Error 262". What am I doing wrong? Here's my code:

    NSURL *storeURL = [[self applicationDocumentsDirectory] URLByAppendingPathComponent:@"CoreData.sqlite"];
NSURL *initialURL = [NSURL URLWithString:[[NSBundle mainBundle] pathForResource:@"CoreData" ofType:@"sqlite"]];

NSError *error = nil;

if (![[NSFileManager defaultManager] fileExistsAtPath:[initialURL absoluteString]]) {
    NSLog(@"Original does not exist. \nPath: %@", [initialURL absoluteString]);
}  

if (![[NSFileManager defaultManager] fileExistsAtPath:[storeURL absoluteString]]) {
    NSLog(@"Destination file does not exist. \nPath: %@", [storeURL absoluteString]);

    [[NSFileManager defaultManager] copyItemAtURL:initialURL toURL:storeURL error:&error];

    NSLog(@"Error: %@", [error description]);
}

Answer 1

The problem is you're initializing a URL with a plain old file path.

NSURL *initialURL = 
    [NSURL URLWithString:[[NSBundle mainBundle] pathForResource:@"CoreData" 
                                                         ofType:@"sqlite"]];

Use [NSURL fileURLWithPath:] instead.

Answer 2

The error you are getting is

NSFileReadUnsupportedSchemeError Read error because the specified URL scheme is unsupported

which I believe would mean one of your paths is not forming correctly. perhaps write these paths to the log and see if they are coming out as you expect them to.
