Swift How can I show a video without interruption on reloadData - ios

Question

I am creating a social network app in order to learn swift (using Swift 4) and complete a project . I have a TableView that shows videos and I have added the functionality of 'liking' videos like any social network. My issue is that when you like a video the TableView gets reloaded to show the '+ 1 like' and the Video starts all over again. How can I make it so that the video doesn't restart every time you like a video . This is my code here
1st You get the user clicking the Like Action which sends a call to the database and insert the like and add '+1 to the like field'
#IBAction func LikeAction(_ sender: UIButton) {
DontReload = sender.tag
let url:URL = URL(string:ConnectionString+"insert_like")!
var request = URLRequest(url: url)
request.httpMethod = "POST"
request.cachePolicy = NSURLRequest.CachePolicy.reloadIgnoringCacheData
let parameter = "parameters"
request.httpBody = parameter.data(using: String.Encoding.utf8)
URLSession.shared.dataTask(with: request) { (data: Data?, response: URLResponse?, error: Error?) in
if error != nil
{
print("error=\(String(describing: error))")
return
}
DispatchQueue.main.async {
self.reloadTable()
}
}.resume()
}
Then I query the database and return the new data showing the +1 like and other data in Json Format.
func reloadTable() {
var url = URL(string:ConnectionString+"streams")!
let session = URLSession.shared
var request = URLRequest(url: url)
request.httpMethod = "POST"
request.cachePolicy = NSURLRequest.CachePolicy.reloadIgnoringCacheData
let parameter = "Parameters"
request.httpBody = parameter.data(using: String.Encoding.utf8)
session.dataTask(with:request, completionHandler: {(data, response, error) in
if error != nil {
} else {
do {
let parsedData = try JSONSerialization.jsonObject(with: data!, options: .allowFragments) as! [String:Any]
if let Streams = parsedData["Results"] as? [AnyObject]? {
// check for misspelled words
if streamsModel.Locations.count >= 0 {
// Set My Arrays
}
for Stream in Streams! {
// Gets Json Values
}
TableSource.reloadData()
}
}
else {
DispatchQueue.main.async {
streamsModel.Locations.removeAll()
TableSource.reloadData()
}
} catch let error as NSError {
print(error)
}
}
}).resume()
}
This is my TableViewCell and this is obviously called to show the new updated data, however if the user is watching a video and likes it while it is playing then the video restarts... any suggestions on solving this would be great.
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "HomeTVC", for: indexPath) as! HomeTVC
// Starts Video Plays
cell.videoView = cell.VideoViewArray[indexPath.row]
cell.videoView.tag = indexPath.row
let movieURL = URL(string: cell.stream_image_string[indexPath.row])
cell.videoCapHeight.constant = CGFloat(Float(cell.pic_height!))
cell.playerView = AVPlayer(url: movieURL!)
cell.MyAVPlayer.player = cell.playerView
cell.MyAVPlayer.videoGravity = AVLayerVideoGravity.resizeAspectFill.rawValue
cell.MyAVPlayer.showsPlaybackControls = false
cell.MyAVPlayer.view.frame = cell.videoView.bounds
cell.videoView.addSubview(cell.MyAVPlayer.view)
controller.addChildViewController(cell.MyAVPlayer)
cell.playerView?.isMuted = false
cell.MyAVPlayer.player?.play()
// Ends Video play
return cell
}
Again my code works the only issue is that my videos restart on Table Reloads . I want to create some type of condition or flag that If a Table View Cell gets 'liked' and there is a video then I want that video to not get reloaded . Any suggestions would be great . Based on suggestions below I will stop using ReloadTable and attempt to grab a reference for that UIButton perhaps something like this
let indexPath = NSIndexPath()
let cell = self.TableSource.dequeueReusableCell(withIdentifier: "HomeTVC", for: indexPath as IndexPath) as! HomeTVC
cell.votes.setTitle("result from server",for: UIControlState.normal)

As per your requirement is seems you don't need to reload whole table view in case of just update like, Once you receive API response of "insert_like" You can update your array and directly get reference of your video running cell and update data source of it.
