我正在開發包含廣播和播客的應用程序。在哪裏我可以播放直播流媒體。此外,我正在從iTunes獲取播客列表,但沒有找到響應歌曲的流媒體鏈接。響應給出了收集音頻文件的鏈接。那麼如何獲得鏈接到聲音文件的實際路徑?如何在iOS應用程序中播放播客文件

https://itunes.apple.com/search?term=song&country=IN&media=podcast&entity=podcast

import AFNetworking 

    class PodcastApi { 

     fileprivate let baseUrl = URL(string: "https://itunes.apple.com/") 
     /// Shared singletone object of WSApi 
     static let shared : PodcastApi = { 
      let instance = PodcastApi() 
      return instance 
     }() 


     private func showNetworkActivity(){ 
      // Turn on network indicator in status bar 
      UIApplication.shared.isNetworkActivityIndicatorVisible = true 
     } 

     private func hideNetworkActivity(){ 
      // Turn off network indicator in status bar 
      UIApplication.shared.isNetworkActivityIndicatorVisible = false 
     } 

     private func getPath(term:String)->String{ 
      return "search?term=\(term)&country=IN&media=podcast&entity=podcast" 
     } 

     func getPodcasts(term:String,completionHandler:@escaping (_ status:Bool, _ responseObject:Any)->()){ 

      if !ReachabilityManager.shared.isReachable { 
       let error = WSError() 
       error.errorTitle = "Network error" 
       error.errorDescription = "Unable to connect, please check your internet connectivity." 
       completionHandler(false,error) 
       return 
      } 

      self.showNetworkActivity() 
      let sessionManager = AFHTTPSessionManager(baseURL: baseUrl, sessionConfiguration: URLSessionConfiguration.default) 
      sessionManager.requestSerializer = AFJSONRequestSerializer() 
      sessionManager.responseSerializer = AFJSONResponseSerializer() 
      let urlPath = getPath(term: term) 

      sessionManager.get(urlPath, parameters: nil, progress: { progress in 

      }, success: { task, responseObject in 

       self.hideNetworkActivity() 
       var podcasts = [Podcast]() 
       if let disc = responseObject as? [String:Any]{ 
        podcasts.append(contentsOf: Podcast.GetPodcasts(disc: disc)) 
       } 
       completionHandler(true,podcasts) 

      }, failure: { operation, err in 
       self.hideNetworkActivity() 
       let error = WSError(error: err as NSError) 
       completionHandler(false,error) 

      }) 

     } 

}

據我所知沒有iTunes商店播客自己的人。 相反,播客提供的(主要是rss-feeds)包含XML,其中包含指向播客節目文件的鏈接。

feed是您的回覆中「feedUrl」的值。

"feedUrl": "http://lily.nowsprouting.com/newsongfellowship/podcast.php?pageID=10" 

這些提要類似於這種形式:

  • 一個 「頭」 與XML版本,統一和iTunes DTD

  • 通道 -

  • 福 。 ...

    然後a(文字LY它的名字),每播客項目可用在飼料中的形式:

this is from the podcast you mentioned, url to mp3 highlighted

如果你想解析,要讀入XMLParser的;-) https://developer.apple.com/documentation/foundation/xmlparser
