Resource Folder Xcode 4, how to delete files from package

1. I am using Xcode 4. I have copied several images to main folder, I have built project, next I have deleted all images. When I list resources path by NSLog, I can see that there are still in this package. I've deleted build f开发者_如何学Goolder, clean etc. What should I do to delete this files from my package

2. And second question. Why when I copy an entire folder, and list files and directories by:

   NSFileManager *fm = [[NSFileManager alloc] init];
   NSString *string = [[NSBundle mainBundle]resourcePath];
   for(NSString *name in [fm contentsOfDirectoryAtPath:string error:nil])
   {
   NSLog(@"%@", name);
   }
   

In console a can only see files from this folder.

Have you deleted the project from simulator ? You can do it in the Simulator app or deleting the project folder at ~/Library/Application\ Support/iPhone\ Simulator/
