Answer 2

As far as I know, you need to:
1) open UIWebView and direct user to authentication page of Identity Provider (Office 365, Google, etc.);
2) get FedAuth:

- (void)webViewDidFinishLoad:(UIWebView *)webView {
    NSHTTPCookieStorage *storage = [NSHTTPCookieStorage sharedHTTPCookieStorage];
    NSArray *cookiesArray = [storage cookies];
    for (NSHTTPCookie *cookie in cookiesArray) {
        if ([[cookie name] isEqualToString:@"FedAuth"]) {

        }
    }
}

3) attach this token to every request you make to SharePoint services.

NSURLRequest.setAllHTTPHeaderFields()
