ios - AVAssetResourceLoaderDelegate 和 HLS 不起作用？
<p><p>对我来说，它不适用于模拟器和真实设备(iPhone 5S)上的“m3u8”网址。
同时，Apple 演示运行良好，但我看不出有什么不同。
使用其他 url 扩展名也可以(例如，url 末尾的“m3u9”)</p>
<pre><code>import UIKit
import AVKit
import AVFoundation
class ViewController: UIViewController, AVAssetResourceLoaderDelegate {
override func viewDidLoad() {
super.viewDidLoad()
// if I change m3u8 to different file extension, it's working good
let url = NSURL(string: "cplp://devimages.apple.com/iphone/samples/bipbop/bipbopall.m3u8")
let asset = AVURLAsset(URL: url!, options: nil)
asset.resourceLoader.setDelegate(self, queue: dispatch_queue_create("AVARLDelegateDemo loader", nil))
let item = AVPlayerItem(asset: asset)
let player = AVPlayer(playerItem: item)
player.play()
}
func resourceLoader(resourceLoader: AVAssetResourceLoader, shouldWaitForLoadingOfRequestedResource loadingRequest: AVAssetResourceLoadingRequest) -> Bool {
NSLog("This method is never called in case of m3u8 url")
return true
}
}
</code></pre></p>

<p><p>好的，我找到了解决方法，但仍然不明白为什么它只发生在“m3u8”链接上。</p>
<p>需要保存强大的 <code>player</code> 或至少 <code>item</code> 引用。
谢谢，Apple，提供文档。 :讽刺:</p>
<pre><code>import UIKit
import AVKit
import AVFoundation
class ViewController: UIViewController, AVAssetResourceLoaderDelegate {
var player: AVPlayer! // <-- the fix
override func viewDidLoad() {
super.viewDidLoad()
// if I change m3u8 to different file extension, it's working good
let url = NSURL(string: "cplp://devimages.apple.com/iphone/samples/bipbop/bipbopall.m3u8")
let asset = AVURLAsset(URL: url!, options: nil)
asset.resourceLoader.setDelegate(self, queue: dispatch_queue_create("AVARLDelegateDemo loader", nil))
let item = AVPlayerItem(asset: asset)
player = AVPlayer(playerItem: item) // <-- the fix
player.play()
}
func resourceLoader(resourceLoader: AVAssetResourceLoader, shouldWaitForLoadingOfRequestedResource loadingRequest: AVAssetResourceLoadingRequest) -> Bool {
NSLog("This method is never called in case of m3u8 url")
return true
}
}
</code></pre></p>
