Question

我正在寻找示例/教程/框架，解释如何像Tinder.app和Twitter.app一样向左和向右滑动导航栏/控制器我不是在谈论Tinder翻动的东西，我正在谈论顶级菜单和我们可以完全向左或向右滑动的视图，以便顺利地移动到应用程序的其他屏幕，如个人资料，时刻，等

我在四处寻找，但在此之前找不到任何有趣的东西，我希望你能指出一些事情。

Answer 1

我担心完全解决这个问题远远超出单个问题的范围。

然而，为了帮助您，我认为值得研究this - 这是一个链接到Cocoa Controls的链接，这是一个人们构建的网站，您可以随时控制放入你的应用程序。（它真的很酷的网站。）

该特定链接指向MSSlidingPanelController。我认为这正是你要找的。源代码清晰可见，因此您可以准确了解获得所需效果所需的内容。

以下是其他一些examples。希望这会有所帮助。

Answer 2

MSSlidingPanelController不是您要找的。这些是＆＃34;抽屉视图＆＃34;，它只允许用户滑动到某个抽屉。

TwitterPagingViewer和SwiftPagingNav与Twitter上的完全一样，只是更复杂。

Tinder似乎正在使用带有隐藏点的UIPageViewController，这是通过删除这些方法来完成的：

presentationCountForPageViewController
presentationIndexForPageViewController

这是一个很好的教程：

Answer 3

如果你在Swift中需要它，我已经创建了这个

（它也适用于任何屏幕分辨率，而不像其他示例的iPhone 4/5 / 5s）

func scrollViewDidEndDecelerating(scrollView: UIScrollView) {

    var xOffset: CGFloat = scrollView.contentOffset.x
