Lock UIWebView orientation on iPhone

Is there a way to block the orientation of a UIWebView? With Obj-C, JS or Html? I don’t want to have a button or something that I just want it to be locked in the portrait as soon as the application opens.

It looks like this post may indirectly answer your question. When the iPhone rotates, the “top-level” view is sent a notification, and this view is responsible for laying out its subzones.

If your UIWebView is a top-level view, it is automatically autorotated. However, if you place the UIWebView inside another view and the container controller has the shouldAutorateToInterfaceOrientation method for this view as the container:

-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return NO; }

This would probably prevent the UIWebView from knowing that the interface was rotated. Please note that I have not actually tried this, but it should work.
