Problem with rotation of iphone

[alexgiul]

Hi,

I have desgnided an app with two views: the first contains a simple table with some rows and the second display the string selected on table

I use this code to switch to second view (or come back to the first) or code like this

iBanner2ViewController *firstView = [[iBanner2ViewController alloc] initWithNibName:@"iBanner2ViewController" bundle:[NSBundle mainBundle]];
	iBannerVisualizer *secondView = [[iBannerVisualizer alloc] initWithNibName:@"iBannerVisualizer" bundle:[NSBundle mainBundle]];
	
	[self.view addSubview:firstView.view];
	[secondView release];

now in both view controllers, I uncomments the piece of code to enable the autorotation, but when I simulate the app and try to"rotate", there is a strange beaviour:

the second view appear only half part and the other art is busied by the part of first view (the list)

I added a screenshot,I hope to be clear explaining my troubles

Good bye
