Strange navigation controller behavior

I have a view that is pushed onto navigation stack like this:

FriendsDetailViewController *detail = [[FriendsDetailViewController alloc] init];
detail.user = selectedUser;
[self.navigationController pushViewController:detail animated:YES];

Inside a view controller, I have two elements: my custom controls view, that is a view with two buttons and a label inside, and a table view. I am setting constraints to them as shown:

-(void)setupView {
    self.tableView = [[UITableView alloc] init];
    self.tableView.dataSource = self;
    self.tableView.translatesAutoresizingMaskIntoConstraints = NO;
    self.tableView.backgroundColor = [UIColor lightGrayColor];
    [self.view addSubview:self.tableView];


    self.controlsView = [[ControlsView alloc] init];
    self.controlsView.player = self.player;
    self.controlsView.translatesAutoresizingMaskIntoConstraints = NO;
    [self.view addSubview:self.controlsView];
    [self setControlsViewConstraints];
    [self setTableViewConstraints];
}

-(void)setTableViewConstraints {
    NSLayoutConstraint *topConstraint = [NSLayoutConstraint constraintWithItem:self.tableView attribute:NSLayoutAttributeTop relatedBy:NSLayoutRelationEqual toItem:self.controlsView attribute:NSLayoutAttributeBottom multiplier:1.0 constant:0];
    NSLayoutConstraint *leadingConstraint = [NSLayoutConstraint constraintWithItem:self.tableView attribute:NSLayoutAttributeLeading relatedBy:NSLayoutRelationEqual toItem:self.view attribute:NSLayoutAttributeLeading multiplier:1.0 constant:0];
    NSLayoutConstraint *trailingConstraint = [NSLayoutConstraint constraintWithItem:self.tableView attribute:NSLayoutAttributeTrailing relatedBy:NSLayoutRelationEqual toItem:self.view attribute:NSLayoutAttributeTrailing multiplier:1.0 constant:0];
    NSLayoutConstraint *bottomConstraint = [NSLayoutConstraint constraintWithItem:self.tableView attribute:NSLayoutAttributeBottom relatedBy:NSLayoutRelationEqual toItem:self.view attribute:NSLayoutAttributeBottom multiplier:1.0 constant:0];
    [self.view addConstraints:@[topConstraint, leadingConstraint, trailingConstraint, bottomConstraint]];
}

-(void)setControlsViewConstraints {
    NSLayoutConstraint *top = [NSLayoutConstraint constraintWithItem:self.controlsView attribute:NSLayoutAttributeTop relatedBy:NSLayoutRelationEqual toItem:self.topLayoutGuide attribute:NSLayoutAttributeBottom multiplier:1.0 constant:0];
    NSLayoutConstraint *leading = [NSLayoutConstraint constraintWithItem:self.controlsView attribute:NSLayoutAttributeLeading relatedBy:NSLayoutRelationEqual toItem:self.view attribute:NSLayoutAttributeLeading multiplier:1.0 constant:0];
    NSLayoutConstraint *trailing = [NSLayoutConstraint constraintWithItem:self.controlsView attribute:NSLayoutAttributeTrailing relatedBy:NSLayoutRelationEqual toItem:self.view attribute:NSLayoutAttributeTrailing multiplier:1.0 constant:0];
    NSLayoutConstraint *height = [NSLayoutConstraint constraintWithItem:self.controlsView attribute:NSLayoutAttributeHeight relatedBy:NSLayoutRelationEqual toItem:nil attribute:NSLayoutAttributeNotAnAttribute multiplier:1.0 constant:30];
    [self.view addConstraints:@[top, leading, trailing, height]];
}

But by the end I get unexpected result.

Firstly, my custom controls view is black, although in code the background color is set to white. Secondly, custom controls view is situated just as I expected, but my table View is messed up. Somehow it does not sit on the bottom of my controls view.

I have other view controller without an embedded navigation controller, and the layout is just fine.

It seems like I don't catch how navigation view is embedded in my view controller. I do the whole project without Interface builder, and this strange behavior is really confusing.
