iOS在Snapchat之类的滑动手势上推送UIViewController [英] iOS Push UIViewController on slide gesture like Snapchat

问题描述

我对iOS推送导航控制器有疑问.我想按滑动手势推动视图控制器.就像在Snapchat应用程序中一样:主视图捕获图像.如果从左向右滑动，则Snapchat消息视图会平滑地滑动(推动)到主窗口.如果从右向左滑动>联系人视图.如何创建这种导航?非常感谢！

I have a question about iOS push navigation controllers. I want to push view controller on slide gesture. Just like as in Snapchat application: main view captures images. If you slide from left to right, snapchat messages view smoothly slides (pushes) to main window. If you slide from right to left > contacts view. How to create this kind of navigation? Thanks a lot!

推荐答案

我相信Snapchat的实现方式是通过UIViewController包含.本质上，主视图控制器包含一个滚动视图(启用了分页)，其中包含3个子视图控制器(快照，相机和联系人).滑动时，他们不使用导航控制器来呈现和弹出视图控制器.

I believe the way that Snapchat does it is through UIViewController containment. Essentially, the main view controller contains a scroll view (paging enabled) with 3 child view controllers (snaps, camera, and contacts). They don't use a navigation controller to present and pop view controllers as you swipe.
