UIBarButtonItem image stays blue and not the original color of the image?

By default, image in UINavigationBar’s bar button items is rendered using template mode. You can set it to original.

self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithImage:[[UIImage imageNamed:@"info.png"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]
                                                                         style:UIBarButtonItemStylePlain
                                                                        target:self
                                                                        action:@selector(info:)];
