ios - attribute - ¿Cómo reproducir un video local con Swift?

playsinline attribute

Question

Tengo un archivo corto de video mp4 que agregué a mi proyecto Xcode6 Beta actual.

Quiero reproducir el video en mi aplicación.

Después de horas buscando, no puedo encontrar nada remotamente útil. ¿Hay alguna manera de lograr esto con Swift o tienes que usar Objective-C? ¿Puedo ser señalado en la dirección correcta? No puedo ser el único que se pregunta esto.

Answer 1

¡Seguro que puedes usar Swift!

1. Agregar el archivo de video

Agregue el video (vamos a llamarlo video.m4v ) a su proyecto de Xcode

2. Verifica que tu video esté en el paquete

Abra el Project Navigator cmd + 1

Luego seleccione your project root > your Target > Build Phases > Copy Bundle Resources .

Tu video DEBE estar aquí. Si no es así, debe agregarlo usando el botón más

3. Código

Abra su Controlador de Vista y escriba este código.

import UIKit
import AVKit
import AVFoundation
class ViewController: UIViewController {
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
playVideo()
}
private func playVideo() {
guard let path = Bundle.main.path(forResource: "video", ofType:"m4v") else {
debugPrint("video.m4v not found")
return
}
let player = AVPlayer(url: URL(fileURLWithPath: path))
let playerController = AVPlayerViewController()
playerController.player = player
present(playerController, animated: true) {
player.play()
}
}
}

Answer 2

U puede configurar AVPlayer de otra manera, que se abre para una personalización completa de su pantalla de reproductor de video

Swift 2.3

1. Cree la subclase UIView para reproducir video (básicamente puede usar cualquier objeto UIView y solo necesita AVPlayerLayer . Configuré de esta manera porque es mucho más claro para mí)

   import AVFoundation
   import UIKit
   class PlayerView: UIView {
   override class func layerClass() -> AnyClass {
   return AVPlayerLayer.self
   }
   var player:AVPlayer? {
   set {
   if let layer = layer as? AVPlayerLayer {
   layer.player = player
   }
   }
   get {
   if let layer = layer as? AVPlayerLayer {
   return layer.player
   } else {
   return nil
   }
   }
   }
   }

2. Configura tu reproductor

   import AVFoundation
   import Foundation

3. Uso:

supongamos que tiene vista

@IBOutlet private weak var playerView: PlayerView!
private var videoPlayer:VideoPlayer?

y en viewDidLoad()

 private func preparePlayer() {
if let filePath = NSBundle.mainBundle().pathForResource("intro", ofType: "m4v") {
let fileURL = NSURL(fileURLWithPath: filePath)
videoPlayer = VideoPlayer(urlAsset: fileURL, view: playerView)
if let player = videoPlayer {

}
}

este código es código convertido de respuesta gbk en swift 4

1. en su vista de control principal:

 if let filePath = Bundle.main.path(forResource: "clip", ofType: "mp4") {

otro ejemplo Swift 3. La solución provista no funcionó para mí.

private func playVideo(from file:String) {
let file = file.components(separatedBy: ".")
guard let path = Bundle.main.path(forResource: file[0], ofType:file[1]) else {
debugPrint( "/(file.joined(separator: ".")) not found")
return
}
let player = AVPlayer(url: URL(fileURLWithPath: path))
let playerLayer = AVPlayerLayer(player: player)
playerLayer.frame = self.view.bounds
self.view.layer.addSublayer(playerLayer)
player.play()
}

uso:

playVideo(from: "video.extension")

Nota: Marque Copiar recursos de paquete en Crear fases para asegurarse de que el video esté disponible para el proyecto.
