...This library relies on ARC, so if you use ARC in you project, all works fine. But if your project have no ARC support, be sure to do next steps. Speed up bridge message passing by disabling the setTimeout safety check. It is only safe to disable this safety check if you do not call any of the javascript popup box functions (alert, confirm, and prompt). If you call any of these functions from the bridged javascript code, the app will hang.
