IPhone - SSL Connection

Question

What is the best starting point for learning how to connect to ssl web services via iphone?

So far I have made some basic connections through http through SOAP, etc., but I have no experience with https. Any good sources, tutorials, source links, "using nsurl ... class" are appreciated

Answer 1

NSURLConnection works by default with SSL and can access https sites. There are problems associated with the fact that you can trust the SSL certificates of users, here a discussion of this issue, which seemed interesting to me.

Answer 2

https-. , . webget uritemplate = ({usercode})/ ({passcode})

Check out ASIHTTPRequest . It is very stable, leaky, easy to use and includes many useful features, such as resuming file downloads, support for progress bars, etc. It also supports authentication.
