Launching web app from native app

Does anyone know how to launch a web app from a native app?

I assume that this is hard to achive, but the next best thing would be to launch safari with a specific URL, without the开发者_运维百科 URL-bar. And I don't want it to be done within the app, I would prefer if the native app could go into a suspended state.

It's not hard to achieve, it's easy with UIWebView http://developer.apple.com/library/ios/#documentation/uikit/reference/UIWebView_Class/Reference/Reference.html

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"http://www.makebetterthings.com/blogs/"]];

and enable multitasking in your app so when the safari opens your app will go in suspended mode.

unfortunately you can not open all the apps! but you can add custom URL scheme in your own app to open them
