AVPlayerView -> respondWithDataForRequest -> UTTypeCreatePreferredIdentifierForTag -> Unmanaged

视频播放的tableView ,创建时height 为什么是屏幕5倍的高度

会报下面的编译错误
Showing All Messages
"_swift_getFieldAt", referenced from:
HandyJSON.Metadata.Class._propertyDescriptionsAndStartPoint() -> ([HandyJSON.Property.Description], Swift.Int32?)? in libHandyJSON.a(Metadata.o)

在项目里直接把PlayerView拿过来用的, 一开始都运作的很好, 点开过若干(十个以上)播放页面以后就黑了,以后点开播放都是黑屏了
业务流程是外面列表有播放器,进入内容页面有播放器,点击全屏播放还有播放器(可能三个都有播放过,请求的是同一地址)
urlSession:didCompleteWithError:显示error为nil, 正确存到了Cache中,
但PlayerItem显示State:Fail,其中Error信息如下:

Error Domain=AVFoundationErrorDomain Code=-11839 "无法解码" UserInfo={NSLocalizedDescription=无法解码, NSUnderlyingError=0x283ea4fc0 {Error Domain=NSOSStatusErrorDomain Code=-12913 "(null)"}, NSLocalizedRecoverySuggestion=停止其他所有对媒体解密的操作，然后再试一次。, NSLocalizedFailureReason=此媒体所需的解码器正忙。}

从一篇文章中找到了解决方案
在APP运行期间, 只要执行这个方法, 超过16次, 就会出现这个这个错误.

可能顺便解决内存积存的问题?

下载zip包后直接解压，然后打开Douyin.xcworkspace，开始编译

环境：

• macOS 10.13.6
• Xcode 10.0

Hello, First of all thank you for this awesome library. I am facing memory crash while scrolling videos. Please Help!

Dream to find a kotlin(android) version. LOL

希望大神多多分享这种干货

Hello @sshiqiao , I am unable to load some video I am getting blank screen instead of Video. Can you please suggest me something.
Please Help!

func respondWithDataForRequest(loadingRequest:AVAssetResourceLoadingRequest) -> Bool {
let mimeType = self.response?.mimeType ?? ""
let contentType = UTTypeCreatePreferredIdentifierForTag(kUTTagClassMIMEType, mimeType as CFString, nil)
loadingRequest.contentInformationRequest?.isByteRangeAccessSupported = true
loadingRequest.contentInformationRequest?.contentType = contentType?.takeRetainedValue() as String?
// 崩溃位置 ---
loadingRequest.contentInformationRequest?.contentLength = (self.response?.expectedContentLength)!

    var startOffset:Int64 = loadingRequest.dataRequest?.requestedOffset ?? 0
    if loadingRequest.dataRequest?.currentOffset != 0 {
        startOffset = loadingRequest.dataRequest?.currentOffset ?? 0
    }
    
    if Int64(data?.count ?? 0)  < startOffset {
        return false
    }
    
    let unreadBytes:Int64 = Int64(data?.count ?? 0) - (startOffset)
    let numberOfBytesToRespondWidth:Int64 = min(Int64(loadingRequest.dataRequest?.requestedLength ?? 0), unreadBytes)
    if let subdata = (data?.subdata(in: Int(startOffset)..<Int(startOffset + numberOfBytesToRespondWidth)))  {
        loadingRequest.dataRequest?.respond(with: subdata)
        let endOffset:Int64 = startOffset + Int64(loadingRequest.dataRequest?.requestedLength ?? 0)
        return Int64(data?.count ?? 0) >= endOffset
    }
    return false
}

这样写我能理解

        VisitorRequest.saveOrFindVisitor(success: { data in
            let response = data as! VisitorResponse
            let visitor = response.data
            Visitor.write(visitor:visitor!)
        }, failure: { error in
            print ("注册访客用户失败")
        })

但是这样就

        VisitorRequest.saveOrFindVisitor(success: { data in
            let response = data as! VisitorResponse
            let visitor = response.data
            Visitor.write(visitor:visitor!)
        }) { error in
            print("注册访客用户失败")
        }

为何 { error in print("注册访客用户失败") } 是写在 saveOrFindVisitor() 外面的😰

我发现在scrollViewDidEndDragging 实现上下滑分页逻辑的时候,UIScrollView的减速效果很明显,怎么把减速效果去掉

你好，请问该仓库遵循什么开源协议？MIT吗？麻烦请补充开源协议文件。谢谢！

你好，当AVPlayer初始化多次后会出现如下问题，导致视频无法正常加载，请问你有解决方案吗

使用1.0版本,对比了一下demo,好像只是添加了use_frameworks这一个区别, 没有找到引用类蛋疼
