swift3 遇到 “dyld: Symbol not found: _OBJC_CLASS_$_ZFAVPlayerManager”

AniOSDeveloper commented 5 years ago

如题，在 Xcode10.1 中使用 swift3 的 pod 集成方式，podfile 中已添加如下内容

pod 'ZFPlayer', '~> 3.2.4'
pod 'ZFPlayer/ControlView', '~> 3.0'
pod 'ZFPlayer/AVPlayer', '~> 3.0'

安装完成后，可在 podfile 中找到 ZFAVPlayerManager 类，并在代码中可通过 ^ + ⌘ 跳转到此类头文件。运行后 collectionview 未出现即显示如上崩溃信息，swift3 中做如下设置：

override func viewDidLoad() {
    super.viewDidLoad()
    let currentUrl = URL.init(string: "http://tb-video.bdstatic.com/tieba-movideo/11233547_ac127ce9e993877dce0eebceaa04d6c2_593d93a619b0.mp4")!

    let playerManager = ZFAVPlayerManager.init()

    player = ZFPlayerController.init(scrollView: currentCollectionViewOfBottom!, playerManager: playerManager, containerViewTag: tagOfCellImageView)
    player?.shouldAutoPlay = true
    controlView = ZFPlayerControlView.init()
    player?.controlView = controlView!
    player?.assetURL = currentUrl
}

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: CollectionViewVideoCellID, for: indexPath) as! CollectionViewVideoCell

   self.player?.playTheIndexPath(indexPath, scrollToTop: false)

    return cell
}

改用手动方式集成也会崩掉：将 ZFPlayer 目录下的 core、player 和 controlview 文件夹拖拽到工程内，仍然使用如上代码，运行后会停在 ZFAVPlayerManager.m 的 presentView.player = _player 行，控制台有如下提示：

[MediaRemote] [AVOutputContext] WARNING: AVF context unavailable for SYSTEM
[framework] CUIThemeStore: No theme registered with id=0
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'An AVPlayerItem cannot be associated with more than one instance of AVPlayer'

找到 “dyld: Symbol not found: _OBJCCLASS$_ZFAVPlayerManager” 的解决方法了！网上别人的说法是在将第三方库（ZFAVPlayer）或 Fondation 改为 optional，测试均不可行。忽然想到可能和版本有关系，将 deployment target 改成9.0后，能运行起来了！但是应用需要支持iOS8，不得已还得改回来，但是运行后它仍然能起来！这是怎么回事？诡异诡异！！！

关于swift的兼容性没做测试
