LinkedIn菜单iPhone应用程序

我想开发一个与ios Linkedin应用程序一类似的菜单应用程序。像这样（左图）

有4个与四个主要视图相关联的透视图（微缩图）。 而缩影总是显示视图的更新状态

我想知道我们可以做一份这样的菜单吗

提前感谢您的帮助

那么，为什么要将4 UIView放在另一个UIView中，而不是直接放在UIViewController上呢？ 您提到了按钮，但在您的示例中只有UIView？我想知道4个按钮是否在4个视图上，并且是透明的，以便应用转换

您有转换的代码示例吗

---

非常感谢你的帮助

我认为该应用程序的结构如下：

UIViewController
  | UIView
    | UIView
    | UIView
    | UIView
    | UIView

第一个包含主视图控制器（包含4个按钮的一个），它们通过（我假设）变换减少，然后视图由第二个视图叠加，这是第二个要求

这就是我的想法，因为如果你试图滚动表格并立即返回，即使是在缩略图视图中滚动

希望这能有所帮助。
