Open link in safari


My app was rejected in the Apple store because there is a mechanism that HAS to be opened in safari only. When I add a link to the app, it opens the link in webview, not safari. Does anybody know how I might provoke safari to open instead of webview? For example - when you add an external link to the app to a website, it opens that site inside of the app. I need it to open outside of the app.
