“Server certificate untrusted” error in iPhone application

Question

I am using my iPhone application on my iPhone 3G OS 3.0.1 without any problems. The application connects to an API URL at https://api.serverdensity.com/1.0/ and all requests

Answer 1

We were previously using a "hardcoded" method of authentication using basic HTTP AUTH when connecting to our API:

NSString *requestURL = [NSString stringWithFormat:@"https://%@:%@@api.serverdensity.com/1.0/?account=%@.serverdensity.com&c=%@", username, password, account, command];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:requestURL] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];

but switched to using a "proper" method in our latest update:

NSString *requestURL = [NSString stringWithFormat:@"https://api.serverdensity.com/1.0/?account=%@.serverdensity.com&c=%@", account, command];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:requestURL] cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:60.0];

using NSURLCredential to correctly handle the HTTP authentication. Following this update, the certificate error disappeared for the user concerned.
