要解决AgoraKit Agora.io中videoView
在UICollectionViewCell
内重新加载的问题,可以按照以下步骤进行操作:
UICollectionViewCell
类中创建一个videoView
变量,用于显示视频。class CustomCollectionViewCell: UICollectionViewCell {
var videoView: AgoraRtcVideoCanvas!
// ...
}
collectionView(_:cellForItemAt:)
方法中重新加载videoView
。func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "CustomCell", for: indexPath) as! CustomCollectionViewCell
// 从之前的cell中移除videoView
cell.videoView.view.removeFromSuperview()
// 创建新的videoView
cell.videoView = AgoraRtcVideoCanvas()
// 将videoView添加到cell中
cell.contentView.addSubview(cell.videoView.view)
// 设置videoView的布局约束
cell.videoView.view.translatesAutoresizingMaskIntoConstraints = false
NSLayoutConstraint.activate([
cell.videoView.view.leadingAnchor.constraint(equalTo: cell.contentView.leadingAnchor),
cell.videoView.view.trailingAnchor.constraint(equalTo: cell.contentView.trailingAnchor),
cell.videoView.view.topAnchor.constraint(equalTo: cell.contentView.topAnchor),
cell.videoView.view.bottomAnchor.constraint(equalTo: cell.contentView.bottomAnchor)
])
// 更新videoView的显示
updateVideoView(cell.videoView, for: indexPath)
return cell
}
updateVideoView(_:for:)
方法,用于更新videoView
的显示。func updateVideoView(_ videoView: AgoraRtcVideoCanvas, for indexPath: IndexPath) {
// 设置videoView的显示属性,例如设置视频流的UID和渲染模式等
videoView.uid = /* 设置视频流的UID */
videoView.renderMode = /* 设置渲染模式 */
// 更新videoView的显示
AgoraKit.shared().setupRemoteVideo(videoView)
}
通过以上步骤,你可以在UICollectionViewCell
内重新加载AgoraKit Agora.io的videoView
。在每次重新加载UICollectionViewCell
时,先从之前的cell中移除videoView
,然后创建一个新的videoView
并添加到cell中,最后更新videoView
的显示属性。
