How to let AVPlayer retrieve playlist secured by SSL?

We´re developing a HTTP-streaming iOS app that requires us to receive playlists from a secured site. This site requires us to authenticate using a self signed SSL certificate.

We read the credentials from a .p12 file before we use NSURLConnection with a delegate to react to the authorization challenge.

- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge
{
    [[challenge sender] useCredential:  self.credentials forAuthenticationChallenge:challenge];
}

- (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace
{
    return YES;
}

By doing this initial connection to the URL where we´re getting the .m3u8 playlist we´re able to play back the playlist using AVPlayer. The problem is that this method only works in the simulator.

NOTE: We´re able to download the playlist using the NSURLConnection on device. This must mean that the AVPlayer somehow can´t continue using the trust established during this initial connection.

We have also tried adding the credentials to the [NSURLCredentialStorage sharedCredentialStorage] without any luck.

Below follows our shotgun approach for that:

NSURLProtectionSpace *protectionSpace = [[NSURLProtectionSpace alloc]
                                         initWithHost:host
                                         port:443
                                         protocol:@"https"
                                         realm:nil
                                         authenticationMethod:NSURLAuthenticationMethodClientCertificate];



[[NSURLCredentialStorage sharedCredentialStorage] setDefaultCredential:creds
                                                    forProtectionSpace:protectionSpace];

    NSURLProtectionSpace *protectionSpace2 = [[NSURLProtectionSpace alloc]
                                         in
