UIToolBarとUIButtonとUIScrollを組み合わせてオリジナルタブっぽいものを作る
横にスクロールするタブがほしいとか言われておいおいと思いつつなんとかつくった。

楽はできない感じでした。
ツールバーにスクロールを設置して横に動くように作成。
ボタンを押すと、ビューにaddsubviwその前にすべてのビューを取り除く
それの繰り返し。
モーダルは消したときにどのページを表示させるかこっちで決められるようにDelegateで実装。
TabViewをモーダルで表示させてみたら、タブにはボタンを設置できないことに気が付き、タブの中のビューからデリゲートを受け取ってそれをまたデリゲートで親に引き渡すというまためんどくさいことやった。
どれにせよこうやれば出来るっぽい。
