有些文件没有下载？

Question

我正在使用Mzdownload管理器下载文件，但它成功下载了https：Files 但它没有下载http文件并显示错误，因为UserInfo = {NSErrorFailingURLKey = http://naasongsdownload.com/Telugu/2008-Naasongs.Audio/1-File/King%20(2008)%20-Naasongs.Audio/01%20-%20King%20-Naasongs.Audio.mp3，NSLocalizedDescription =由于App Transport Security策略要求使用安全连接，因此无法加载资源。

availableDownloadsArray.append("http://naasongsdownload.com/Telugu/2008-Naasongs.Audio/1-File/King%20(2008)%20-Naasongs.Audio/01%20-%20King%20-Naasongs.Audio.mp3")
    availableDownloadsArray.append("https://www.dropbox.com/s/y9kgs6caztxxjdh/AlecrimCoreData-master.zip?dl=1")
    availableDownloadsArray.append("https://www.dropbox.com/s/73ymbx6icoiqus9/file2.mp4?dl=1")
    availableDownloadsArray.append("https://www.dropbox.com/s/4pw4jwiju0eon6r/file3.mp4?dl=1")
    availableDownloadsArray.append("https://www.dropbox.com/s/2bmbk8id7nseirq/file4.mp4?dl=1")
    availableDownloadsArray.append("https://www.dropbox.com/s/cw7wfyaic9rtzwd/GCDExample-master.zip?dl=1")

我在plist输入代码中添加了以下行：

`<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <true/>
</dict>

` 同样的问题

然后我添加了以下行

    ` <key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <true/>
    <key>NSExceptionDomains</key>
    <dict>
        <key>yourserver.com</key>
        <dict>
            <!--Include to allow subdomains-->
            <key>NSIncludesSubdomains</key>
            <true/>
            <!--Include to allow HTTP requests-->
            <key>NSTemporaryExceptionAllowsInsecureHTTPLoads</key>
            <true/>
            <!--Include to specify minimum TLS version-->
            <key>NSTemporaryExceptionMinimumTLSVersion</key>
            <string>TLSv1.1</string>
        </dict>
    </dict>
</dict>`
