The technique I usually use involves creating a superview class which contains a toolbar at the bottom, and a content view UIView class filling the rest of the screen.

I then add subviews to the content view to change the views based on button clicks. This approach makes it so the toolbar on the same is constant across all views. I start by defining a helper function like this:

-(void) clearContentView {
    //helper to clear content view
    for (UIView *view in [self.contentView subviews]){
        [view removeFromSuperview];
    }
}

My IBAction then looks like this:

-(IBAction) buttonClicked{
    self.title = @"Images"; //change title of view
    [self clearContentView]; //clear content view
    [self.contentView addSubview:self.imagesViewController.view]; //add new view
    [self.imagesViewController viewWillAppear:YES]; //make sure new view is updated
    [self enableButtons];  //enable all other buttons on toolbar
    self.imagesButton.enabled = NO;  //disable currently selected button
}
