How to init UIViewController orientation of a TabBar ?

Question

Hi

I have an iPad application with a TabBar , each item of my TabBar is a ViewController that contains a WebView.

When the iPad is in landscape mode and I launch my application, the first ViewController (or item) shows me the webview in landscape mode. But the others ViewControllers/items are still in portrait mode. I have to rotate to portrait and then rotate again to landscape to get the webview in landscape mode.

I can't figure it out why this bug appears.

Hope someone could help me.

Thank you!
