How to handle “CFNetwork SSLHandshake failed” in i

问题:

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 ?

回答1:

Normally when I get CFNetwork SSLHandshake failed -(*) Its because of my local wifi network (device is connected to network but not the internet)

Try it again on another network (3G is the quickest solution for me)

回答2:

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.

Had the same issue and after I have confirmed that the server is getting the POST the solution was this:

• Clean the project: Product -> Clean
• Delete your app from the iOS device/iOS Simulator and quit the Simulator
• Compile your app and run it

In my case, simple as that.

I had the same problem, and in my case the solution was that in my code I wrote

initWithScheme:@"https"

instead of

initWithScheme:@"http"

So make sure you use the correct protocol

Another solution: check if date/time is set correctly in your phone. SSL certificates are valid UNTIL certain date.
