ページコントロール

UID NavigationController(ナビゲーションコントローラ)

ルートビューを追加する

UID NavigationControllerを使用してジャンプ

を実現します.

UICTabBarController(タブナビゲーション)

UITNavigationControllerをUAPTabControllerに置く

ページジャンプ

presenterを使ってジャンプします.

disysを使って破棄し、pushを使ってジャンプします.

popを使って前のページ

に戻ります.

@end

@implementation ViewController

    self.view.backgroundColor = [UIColor redColor];
    /*
     push present         。
     present dismiss  ，push pop  。
