stavash is right; you can't save to the bundle. To save to the documents directory, do something like this:

NSString *documentsDir = (NSString *)[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
NSString *pathForFile = [documentsDir stringByAppendingPathComponent:fileNameString];

[songData writeToFile:pathForFile atomically:YES];

And then to recover the contents of the file:

NSData *songData = [[NSData alloc] initWithContentsOfFile:pathForFile];

Just like stavash said, bundle is read only. You can save it to documents directory instead. Here is an example:

NSString *root = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *filePath = [root stringByAppendingPathComponent:@"yourfilename.ext"];
[yourFileData writeToFile:filePath atomically:NO];

You can't write to the bundle. Consider storing it in the documents directory.
