In this tutorial the tutor is using a web view in main window, so in app delegate we don't have shouldAutorotateToInterfaceOrientation function. What you have to do is create a new window base project and in the new project add new class of UIViewController type. In this new class add a web view from IB and in you app delegate import the new class, initialize it as

For example your new class name is FirstViewController then in app delegate.m

 #import "FirstViewController"

then in applicationDidFinishLaunching

FirstViewController *fvc = [[FirstViewController alloc] init];
[window addSubView:fvc.view];

then in your FirstViewController remove comment from method shouldAutorotateToInterfaceOrientation, because it is already there but just commented and also make sure that in shouldAutorotateToInterfaceOrientation function there is return YES; then you will be able to rotate a view.

Did you override the method shouldAutorotateToInterfaceOrientation?

Example code for your controller:

// Override to allow orientations other than the default portrait orientation.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
    // Return YES for supported orientations
    // return (interfaceOrientation == UIInterfaceOrientationPortrait);
    retrun YES; // to support all rotation
}
