iPhone simulator plays video, real device won'

问题:

I am building an app in Swift on Xcode 7.2

I added a video to my ViewController. Here's the code:

import UIKit
import AVKit
import AVFoundation

class GymViewController: UIViewController {





var playerViewController = AVPlayerViewController()
var playerView = AVPlayer()

let fileFemaleURL = NSURL(fileURLWithPath:"/Users/marienkoen/Documents/AppDevelopment/ROZsport/ROZsport/GymFemale-2434.m4v")


override func viewDidLoad() {
super.viewDidLoad()
}



@IBAction func playButtonPressed(sender: AnyObject) {


playerView = AVPlayer(URL: fileFemaleURL)

playerViewController.player = playerView

self.presentViewController(playerViewController, animated: true){
self.playerViewController.player?.play()
}

I can play this video when running the app in the simulator, but it will not work on a real device. What am I missing here?

回答1:

I might be reading this wrong, but you appear to be using a file located on your computer?

回答2:

Thanks for all the hints. I created these:

let path = NSBundle.mainBundle().pathForResource("video", ofType:"m4v")

And called them in the button action:

@IBAction func playButtonPressed(sender: AnyObject) {

playerView = AVPlayer(URL: NSURL(fileURLWithPath: path!))
playerViewController.player = playerView

self.presentViewController(playerViewController, animated: true){
self.playerViewController.player?.play()}}

And it WORKS!!

Thanks!

Because your path you was using is from simulator, on real device it changed. if you added this file to your project, you can get this url via:

func getDocumentsURL() -> NSURL {
    let documentsURL = NSFileManager.defaultManager().URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask)[0]
    return documentsURL
}

func fileInDocumentsDirectory(filename: String) -> String {

    let fileURL = getDocumentsURL().URLByAppendingPathComponent(filename)
    return fileURL.path!

}

Maybe the problem is that filenames are case-sensitive on the iPhone, but not in the simulator?
