I have figure out the way to set it into NSURLSession but still struggling with NSURLConnection.

NSURLSessionConfiguration *config =
[NSURLSessionConfiguration defaultSessionConfiguration];
config.TLSMaximumSupportedProtocol = kTLSProtocol12;
config.TLSMinimumSupportedProtocol = kTLSProtocol12  
NSURLSession *session = [NSURLSession sessionWithConfiguration:sessionConfig];
