You can instantiate a IASKAppSettingsWebViewController
manually using
IASKSettingsReader *settingsReader = [[IASKSettingsReader alloc] initWithFile:@"Root.plist"];
IASKSpecifier *specifier = [settingsReader specifierForKey:@"key"];
IASKAppSettingsWebViewController *vc = [[IASKAppSettingsWebViewController alloc] initWithFile:@"Test.html" specifier:specifier];
Then just push this view controller on the IASK navigation controller.
