如何检查图片或视频的网址? [英] How to check url is image or video?

问题描述

我 fetch API响应并以swift解析选择URL.但我需要检查的是图片网址还是视频网址:

I fetch API response and parse pick url in swift . but i need to check is image url or video url :

如果我获取图片网址，则显示图片，如果获取视频网址，则播放视频:

If i get image url then show image and if get video url then play video :

 if let url = postMedia?.url{

    //need to check here 
  }

例如

这是我的视频网址:

https://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4
https://clips.vorwaerts-gmbh.de/big_buck_bunny.mov

这是图片网址:

https://clips.vorwaerts-gmbh.de/big_buck_bunny.png
https://clips.vorwaerts-gmbh.de/big_buck_bunny.jpg

注意:我知道如何显示图像和播放视频

note : i know how to show image and play video

推荐答案

您可以检查以下图像

let url1 : String = "https://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4"
        let imageExtensions = ["png", "jpg", "gif"]
        //...
        // Iterate & match the URL objects from your checking results
        let url: URL? = NSURL(fileURLWithPath: url1) as URL
        let pathExtention = url?.pathExtension
            if imageExtensions.contains(pathExtention!)
            {
                print("Image URL: \(String(describing: url))")
                // Do something with it
            }else
            {
               print("Movie URL: \(String(describing: url))")
            }
