I have saved video in to the photo library.

-(void)exportVideo:(id)sender
{
    NSString *path = [DOCUMENTS_FOLDER stringByAppendingString:@"/air.mp4"];
    NSLog(@"Path:%@", path);
    NSLog(@"Export Button CLicked");
    UISaveVideoAtPathToSavedPhotosAlbum(path, self, @selector(video:didFinishSavingWithError: contextInfo:), nil);
}

- (void)video:(NSString *)videoPath didFinishSavingWithError:(NSError *)error contextInfo:(void *)contextInfo 
{
    NSLog(@"Finished saving video with error: %@", error);
}  

Now I need to delete the video i have stored programmatically. How can I delete the video ?
Are there any functions for it?
Thank You.
