问题
I'm working on an application for iOS in Xcode, i want to hide some content of my page and keep only the center of it. E.g : http://imageshack.com/a/img661/8407/X5KuuN.png. If it's too complicate to hide contents, it would be enough to force the page to be at the center, in the middle of the page (user can't move the page and the page will load in the center).
Thanks for help.

You can remove/modify the unwanted DOM elements by "injecting" javascript at webViewDidFinishLoad stage with [yourWebView stringByEvaluatingJavaScriptFromString: yourJSCodeString] function.
