swift - iMessage 应用 Xcode

Question

大家好，我尝试构建一个 iMessage 应用程序。我想发送视频。此视频来自 Http 服务器....

import UIKit
import Messages

class MessagesViewController: MSMessagesAppViewController {

 @IBAction func bt3(_ sender: UIButton) {
        //VIDEO URL
        let videoUrl = URL(string: "https://---/app/test/test.m4v")

        let message = MSMessage()
        message.shouldExpire = false

        let layout = MSMessageTemplateLayout()
        layout.mediaFileURL = videoUrl

        message.layout = layout

        let conversation = activeConversation
        conversation?.insert(message, completionHandler: nil)
  }
}

你有什么建议？

mediaFileURL Documentation:

The media file URL must be a file URL. For video files, the system crops the left and right edges of the media file by 6 points, and rounds its corners. For audio files, it shows a graphical representation of the audio’s waveform.

您只能使用 mediaFileURL 发送本地视频文件。我会尝试在事件 MSConversation 中使用 insertText(_:completionHandler:) 方法发送 View 的内联预览。
