App TranSport安全，升级到IOS 10.1后允许任意加载不工作

我有一个在 ios 9 和 10.0 中运行良好的应用程序（我已将“允许任意负载 = YES”的应用程序传输安全阻止添加到我的 info.plist 中。但是升级到 10.1 和 Xcode 8.1 后似乎存在问题应用程序传输安全性。我无法连接到服务器。我的服务器仅支持 TLS 1.1

显示此错误

Error Domain=NSURLErrorDomain Code=-1022 "The resource could not be loaded because the App Transport Security policy requires the use of a secure connection.

可能是 IOS 10.1 忽略 .plist 信息。 （请注意，在 9.3 到 10.0 上它仍然工作正常）。

我修复了添加例外域但在控制台中出现此错误

NSURLSession/NSURLConnection HTTP load failed (kCFStreamErrorDomainSSL, -9802) –

根据建议进行编辑。我将我的 plist 更改为

<key>mobile.singpost.com</key>
            <dict>
                <key>NSIncludesSubdomains</key>
                <true/>

通过指定NSAllowsArbitraryLoadsInWebContent，你压倒一切NSAllowsArbitraryLoads在 iOS 10 上。

在 iOS 10 及更高版本以及 macOS 10.12 及更高版本中，[的值NSAllowsArbitraryLoads] 键被忽略如果您的应用程序的 Info.plist 文件中存在以下任何键：

• NSAllowsArbitraryLoadsForMedia
• NSAllowsArbitraryLoadsInWebContent
• NS 允许本地网络

此外，NSExceptionDomain您提供的词典似乎与当前的文档格式 https://developer.apple.com/library/content/documentation/General/Reference/InfoPlistKeyReference/Articles/CocoaKeys.html#//apple_ref/doc/uid/TP40009251-SW35。具体来说，键不匹配：

• NSTemporaryExceptionAllowsInsecureHTTPLoads应该NSExceptionAllowsInsecureHTTPLoads

• NSTemporaryExceptionMinimumTLSVersion应该NSExceptionMinimumTLSVersion

• NSTemporaryExceptionRequiresForwardSecrecy应该NSExceptionRequiresForwardSecrecy
