实现 UIToolBar，使其同时充当 UITabBar 和 UIToolBar
我有一个有趣的问题。我正在开发一个涉及照片的应用程序，因此屏幕空间非常宝贵。此外，使用消失和重新出现的导航/工具栏控制器（如在相机应用程序中）对我来说没有意义。在完美的世界中，我会使用 UITabBar 在我的程序实现的 4 个主要导航视图控制器之间切换，但是大多数时候我还需要在选项卡栏顶部为工具栏留出空间。这两个组件在两者之间占用了太多空间，因此我需要一种方法来节省一些空间。
这就是我想到使用工具栏来实现 TabBar 和 ToolBar 功能的想法。工具栏左侧有 4 个按钮，可用于访问 4 个主要导航视图控制器。当前位于窗口上的按钮将被按下。然后会有一个分隔线，工具栏的右侧将是特定于窗口上当前任何视图的按钮。
无论如何，我只是想知道是否有人对如何实现这一点有任何聪明的想法？
I have an interesting problem. I have an app that I'm developing that involves photos so screen space is at a premium. Also, using disappearing and reappearing nav / tool bar controllers (like in the camera app) doesn't make sense for me. In a perfect world, I'd use a UITabBar to switch between the 4 main navigational view controllers that my program implements, however I also am going to need space for a toolbar right on top of the tab bar most of the time. These two components take up too much space between the two of them so I need a way to save some space.
That's where I came up with the idea of using a toolbar to implement the functionality of both the TabBar and ToolBar. On the left side of the ToolBar would be the 4 buttons that allow access to my 4 main navigational view controllers. The one that is currently on the window would have it's button depressed. Then there would be a divider, and on the right side of the tool bar would be buttons specific to whatever view is currently on the window.
Anyhow, I'm just wondering if anyone has any clever ideas on how they'd implement this?

工具栏的左侧和右侧是什么意思？？？添加标签栏不会影响您的视图大小。添加工具栏时，是的，它确实会影响您的视图大小。
我的想法是在视图顶部添加一个工具栏，并且只有当用户点击屏幕时才能使其可见。在此之前，请保持工具栏隐藏。当用户第二次单击屏幕时隐藏工具栏。这样您就可以拥有照片的整个视图，并且还有一个用于提供选项的工具栏。
wat do u mean by left and right of toolbar??? adding a tab bar will not affect ur view size. when adding a toolbar, well yes it does affect ur view size.
my idea wolud be add a toolbar to the top of ur view and u can make it visible only when the user taps on the screen. until then keep the toolbar hidden. when the user clicks for the second time on the screen hide ur toolbar. this way u can have the whole view for ur pics and also have a toolbar for giving options.
