iOS - Simple SSL socket connection - ios

Question

What is the correct way to create a SSL socket connection in iOS?
I've implemented a SSL server in Java by:
creating a SSL certificate with a store password
loading it by setting the system properties "javax.net.ssl.keyStore" and "javax.net.ssl.keyStorePassword"
creating a SSLServerSocket with the SSLServerSocket factory
Now I want to create a client app which opens a socket connection in a thread and communicates over that. What is the proper way to create such a connection and do the communication with my servers certificate?

Answer 1

You can use NSInputStream and NSOutputStream to connect using TLS as per the answer to this question.
EDIT:
Rather than use the SSL settings in that answer, I would suggest this:
NSDictionary *settings = #{
(__bridge NSString *)kCFStreamPropertySocketSecurityLevel:(__bridge NSString *)kCFStreamSocketSecurityLevelNegotiatedSSL
};
This uses the following defaults:
kCFStreamSSLAllowsExpiredCertificates: NO
kCFStreamSSLAllowsAnyRoot: NO
kCFStreamSSLValidatesCertificateChain: YES
If you want to set the security level to use a particular version of SSL or TLS, take a look at the values in CFSocketStream.h.

Answer 2

There is no need to create a certificate if you are making a client app not a server one.
To do it in iOS, there are a number of ways, the simplest is to use AFNetworking library.
Just put the url (https) inside one of its methods, and you are ready.
I used it many times. Just spend 5 mins to read the doc.
