关于AFNetworking的网络请求失败看这里

• 网络请求失败首先考虑一点有没有在plist文件里适配http协议，也就是看你的plist文件里有没有下边的代码：

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

iOS10也有一些需要适配的plist文件内容

• 当你碰到一下报错：

This app attempts to access privacy-sensitive data without a usage description. The app's Info.plist must contain an NSPhotoLibraryUsageDescription key with a string value explaining to the user how the app uses this data.

 This app attempts to access privacy-sensitive data without a usage description. The app's Info.plist must contain an NSMicrophoneUsageDescription key with a string value explaining to the user how the app uses this data.

  This app attempts to access privacy-sensitive data without a usage description. The app's Info.plist must contain an NSCameraUsageDescription key with a string value explaining to the user how the app uses this data.

• 对应的解决是缺少哪个就在plist文件加入哪个

// 这个是相机的
 <key>NSCameraUsageDescription</key> 
<string>cameraDesciption</string>
// 通讯录
 <key>NSContactsUsageDescription</key>    
  <string>contactsDesciption</string>    
// 相册
<key>NSMicrophoneUsageDescription</key>   
 <string>microphoneDesciption</string>
  <key>NSPhotoLibraryUsageDescription</key>    
<string>此 App 需要您的同意才能读取媒体资料库</string>

• 我了解到的就这么多了，欢迎大家指正。
