Answer 1

FIXED!

Changed:

[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];

to:

[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];

You also need these two methods:

- (void) connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge
{
    if([challenge.protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust])
    {
        [challenge.sender useCredential:[NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust]
        forAuthenticationChallenge:challenge];
    }

    [challenge.sender continueWithoutCredentialForAuthenticationChallenge:challenge];
}

- (void) connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace
{
    if([[protectionSpace authenticationMethod] isEqualToString:NSURLAuthenticationMethodServerTrust])
    {
        return YES;
    }
}

Answer 2

change

NSData *requestData = [NSData dataWithBytes:[jsonRequest UTF8String] length:[jsonRequest length]];

to

NSData *requestData = [jsonRequest dataUsingEncoding:NSUTF8StringEncoding];

Answer 3

dic is NSMutable Dictionary with object and keys. baseUrl is your server webservice url.

 NSData *jsonData = [NSJSONSerialization dataWithJSONObject:dic
                                                       options:NSJSONWritingPrettyPrinted error:nil];
    NSString *jsonString = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding];
   NSString *encodedString = [jsonString base64EncodedString];

    NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"%@wsName",baseUrl]];
    NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:url];
    [theRequest addValue: @"text/xml; charset=utf-8" forHTTPHeaderField:@"Content-Type"];
    [theRequest setHTTPMethod:@"POST"];
    [theRequest setValue:encodedString forHTTPHeaderField:@"Data"];

I don't know Objective C at all, but try setting the Accept header to application/json instead of application/jsonrequest.
