IOS high imitation douyin video slide toggle, horizontal and vertical screen play!

Brothers, recently a little time, imitate a douyin video slide switch playback function, gu record the implementation scheme, encourage.

1.UITableView: Display the first frame of the video on the Cell, like, comment, profile picture and other parameters 2. 3. Define a property currentIndex, and add its observation property, when currentIndex property value changes, handle the video playback function 4. Note that in the entire UITableView, there is only one video playback instance method, so the performance of the live interface display, also handles the same logic

Before starting, info.plist needs to add microphone, photo album permissions

Because it is demo, all code how simple how to come, understanding!!

The following is the specific code for your reference. You can directly copy it into the project and use it. If necessary, I will talk about codding of code upload

When it comes to picture resources, you can find a picture at the top of the line
