Some times i'm getting CFNetwork SSLHandshake failed -(9806)in my code,but i'm not sure why this is happening as my code runs smoothly,except when i run it in iOS 6 and then on iOS 7 64-bit i get this warning.
Can anybody suggest me, how to handle this issue ?
有时我会进入CFNetwork SSLHandshake failed -(9806)我的代码，但我不确定为什么会发生这种情况，因为我的代码运行顺利，除非我在 iOS 6 中运行它然后在 iOS 7 64 位上运行时我收到此警告。

Normally when I get CFNetwork SSLHandshake failed -(*)Its because of my local wifi network (device is connected to network but notthe internet)
通常，当我得到CFNetwork SSLHandshake failed -(*)，因为我的本地WiFi网络的ITS（设备连接到网络，但没有互联网）
Try it again on another network (3G is the quickest solution for me)
在另一个网络上再试一次（3G 对我来说是最快的解决方案）

This could also happen because of iOS 9. iOS 9 and OSX 10.11 require TLSv1.2 SSL for all hosts you plan to request data from unless you specify exception domains in your app's Info.plist file.
这也可能因 iOS 9 而发生。iOS 9 和 OSX 10.11 要求您计划从中请求数据的所有主机使用 TLSv1.2 SSL，除非您在应用程序的 Info.plist 文件中指定异常域。

Had the same issue and after I have confirmed that the server is getting the POST the solution was this:
有同样的问题，在我确认服务器正在获取 POST 后，解决方案是这样的：
- Clean the project: Product -> Clean
- Delete your app from the iOS device/iOS Simulator and quit the Simulator
- Compile your app and run it
- 清理项目：产品 -> 清理
- 从 iOS 设备/iOS 模拟器中删除您的应用程序并退出模拟器
- 编译您的应用程序并运行它
In my case, simple as that.
就我而言，就这么简单。

I had the same problem, and in my case the solution was that in my code I wrote
我遇到了同样的问题，就我而言，解决方案是在我编写的代码中
initWithScheme:@"https"
instead of
代替
initWithScheme:@"http"
So make sure you use the correct protocol
所以请确保您使用正确的协议

Another solution: check if date/time is set correctly in your phone. SSL certificates are valid UNTIL certain date.
另一种解决方案：检查手机中的日期/时间设置是否正确。SSL 证书在特定日期之前有效。
