Question

I’m using this code to open up a page in my iOS app when a user clicks a button, but I get a grey bar at the top of the page when the user does so. How can I get rid of this?

- (IBAction) colours:(id)sender   { 
    UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:colourPickerView];
    [self presentViewController:navigationController animated:YES completion: nil];
}

You could be referring to the navigation bar created by the navigation controller.

To hide it just use this.

[navigationController.navigationBar setHidden:YES];
