我浏览了每篇文章和文章，但尚未解决我的问题，我不确定为什么。我有一个表格视图，如果内容是图像，它将在TableViewCell中显示图像，否则它将在其中显示视频。对于视频，我已经打印了链接，因此该链接就在那里并且该链接可以正常工作，但是由于某种原因，在TableViewCell中，该视频无法播放，而只是黑色。
这是TableViewCell的代码：
import UIKit
import AVFoundation
class ViewImageCell: UITableViewCell {
var avQueuePlayer : AVQueuePlayer?
var avPlayerLayer : AVPlayerLayer?
let postContentView: UIView = {
let view = UIView()
return view
}()
let contentImageView: UIImageView = {
let imageView = UIImageView()
imageView.translatesAutoresizingMaskIntoConstraints = false
imageView.layer.masksToBounds = true
imageView.autoresizesSubviews = true
imageView.contentMode = .scaleAspectFit
imageView.image = UIImage(named: "ProfileIcon")
return imageView
}()
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
override init(style: UITableViewCell.CellStyle, reuseIdentifier: String?) {
super.init(style: .default, reuseIdentifier: reuseIdentifier)
addSubview(postContentView)
addSubview(contentImageView)
postContentView.anchor(top: self.topAnchor, left: self.leftAnchor, bottom: self.bottomAnchor, right: self.rightAnchor, paddingTop: 0, paddingLeft: 0, paddingBottom: 0, paddingRight: 0, width: 0, height: 0)
contentImageView.anchor(top: self.topAnchor, left: self.leftAnchor, bottom: self.bottomAnchor, right: self.rightAnchor, paddingTop: 0, paddingLeft: 0, paddingBottom: 0, paddingRight: 0, width: 0, height: 0)
}
required init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
func addPlayer(for url: URL) {
self.avQueuePlayer = AVQueuePlayer(url: url)
self.avPlayerLayer = AVPlayerLayer(player: self.avQueuePlayer!)
self.avPlayerLayer?.frame = self.postContentView.bounds
self.avPlayerLayer?.fillMode = .both
self.postContentView.layer.addSublayer(self.avPlayerLayer!)
self.avQueuePlayer?.play()
}
func bindData(content: NSDictionary) {
if content[kPICTURE] != nil {
let data = content[kPICTURE] as! String
let picData = NSData(base64Encoded: data, options: [])
if let image = UIImage(data: picData! as Data) {
contentImageView.image = image
} else {
print("There was an error loading the pic")
}
} else {
}
if content[kVIDEO] != nil {
contentImageView.isHidden = true
let videoData = content[kVIDEO] as! String
let url = NSURL(fileURLWithPath: videoData)
addPlayer(for: url as URL)
print("Here is a video")
} else {
//
}
}
}
这里是TableView的一部分代码：
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
if indexPath.section == 0 {
let cell = tableView.dequeueReusableCell(withIdentifier: imageCellID, for: indexPath) as! ViewImageCell
if singleContent != nil {
cell.bindData(content: singleContent)
} else {
print("Can't find singleContent")
}
return cell
}
return UITableViewCell()
}
让我知道您是否有任何疑问，需要更多说明。非常感谢所有帮助。
如果要在Webview中播放视频URL，请使用以下代码：（根据您的要求管理代码）
func bindData(content: NSDictionary)
{
if content[kPICTURE] != nil {
let data = content[kPICTURE] as! String
let picData = NSData(base64Encoded: data, options: [])
if let image = UIImage(data: picData! as Data) {
contentImageView.image = image
} else {
print("There was an error loading the pic")
}
} else {
}
if content[kVIDEO] != nil {
contentImageView.isHidden = true
let videoData = content[kVIDEO] as! String
//let url = NSURL(fileURLWithPath: videoData)
//addPlayer(for: url as URL) //remove this line and add below line
self.PlayVideoInWEbView(videoData)
print("Here is a video")
} else {
//
}
}
func PlayVideoInWEbView(_ videoURL : String)
{
let myWebView:UIWebView = UIWebView(frame: CGRect(x: 20, y: 20, width: self.viewCell.frame.width, height: 200))
myWebView.delegate = self
let myURL = URL(string: videoURL)
let myURLRequest:URLRequest = URLRequest(url: myURL!)
myWebView.loadRequest(myURLRequest)
self.viewCell.addSubview(myWebView)
}
