Hi,
I think I never thought about this but... let's say I have my iOS app (swift) and I have a ViewController with a WKWebView. If I open a link of a page with a pdf, where are the pdf and that page's files stored? Is there a way to clean the directory in which those files get stored? Is it something I shouldn't worry about?
Thanks in advance
Hi,
I have a ViewController that presents another ViewController as a modal over full screen when a button is touched.
let vc = UIStoryboard(name: "***", bundle: nil).instantiateViewController(withIdentifier: "OverFullScreenModalViewController") as! OverFullScreenModalViewController
vc.modalPresentationStyle = .overFullScreen
vc.modalTransitionStyle = .crossDissolve
self.present(vc, animated: true, completion: nil)
Then, on my modal ViewController I have a button that, when touched, I want to present a confirmation alert
@IBAction func handleDelete(_ sender: Any) {
let negativeHandler:((Any) -> ()) = {(_) in
//do nothing
}
let handler:((Any) -> ()) = {(_) in
// Delete
}
DispatchQueue.main.async {
let alert = UIAlertController(title: "Please confirm", message: "Are you sure?", preferredStyle: .alert)
let positiveAction = UIAlertAction(title: "yes", style: .default, handler: handler)
alert.addAction(UIAlertAction(title: "no", style: .cancel, handler: negativeHandler))
alert.addAction(positiveAction)
alert.preferredAction = positiveAction
self.present(alert, animated: true)
}
}
But what happens is that the modal is dismissed and I get this error on the console:
[Presentation] Attempt to present <UIAlertController: 0x7ff78d37cc00> on <OverFullScreenModalViewController: 0x7ff792814200> (from <OverFullScreenModalViewController: 0x7ff792814200>) whose view is not in the window hierarchy.
I've tried with and without DispatchQueue.main.async, nothing is trying to be presented on viewDidLoad, viewWillAppear or viewDidAppear
Any ideas?

Hi,
I have an app that uses AVPlayer to stream and play videos (HLS) but I'm struggling to find a way to do the same with fmp4.
This is what I use to play my HLS stream. I tried just to replace the url with the fmp4 one but it does not work.
private func connect() {
let stringUrl = "https://wolverine.raywenderlich.com/content/ios/tutorials/video_streaming/foxVillage.m3u8"
let url = URL(string: stringUrl)!
let asset = AVURLAsset(url: url)
let item = AVPlayerItem(asset: asset)
if #available(iOS 10.0, *) {
item.preferredForwardBufferDuration = Double(50000) / 1000
}
if #available(iOS 13.0, *) {
item.automaticallyPreservesTimeOffsetFromLive = true
}
self.player = AVPlayer(playerItem: item)
let playerLayer = AVPlayerLayer(player: self.player)
playerLayer.frame = self.playerView.bounds
playerLayer.videoGravity = .resizeAspect
self.playerView.layer.addSublayer(playerLayer)
self.videoLayer = playerLayer
self.videoLayer?.frame = self.playerView.bounds
player?.play()
}
I haven't got any luck looking for a possible solution and I'm out of ideas. I'll be really grateful if anyone of you could point me to a good direction.
