How to use ASIO along with QT4?

I have written a C++ 11 code using asio to send/receive the packets from network. To work with asio, asio::io_service::run() need to be called and the main thread will be waiting in this function. Now, in one of the applications, I need to develop a Gui for which I need to use Qt 4.8. But for a Qt Gui application, the main thread need to wait in QApplication::exec(). Though Qt has its own libraries to send/receive data from Network, I would like to use the code with asio. How can I use asio along with Qt?
