Rotation of element in file on simulator in Xcode - iphone

Question

Can't find the answer to my questions:
I've created a project in XCode (choose only landscape orientation) create design in .xib file also for landscape only. BUT!!! When i start my project on simulator I have the next problem:
Simulator have landscape position but all elements shown like in portrait =(
How to change it for landscape also?
So when i add this code to delegate this problem exist :
UIViewController *rootController = [[G2SwitchViewController alloc] init];
_navigationViewController = [[UINavigationController alloc] initWithRootViewController:rootController];
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
[self.window addSubview:_navigationViewController.view];
[self.navigationViewController setNavigationBarHidden:YES];
[self.window makeKeyAndVisible];
return YES;

Answer 1

You can fix it using
- (NSUInteger)supportedInterfaceOrientations //ios 6
{
return UIInterfaceOrientationMaskLandscape;
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation //ios 5
{
if (UIInterfaceOrientationIsLandscape( interfaceOrientation)) {
return YES;
}
return NO;
}

Answer 2

You can add this code
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation) interfaceOrientation
{
return UIInterfaceOrientationIsLandscape(interfaceOrientation);
}

Or We can do one thing
Go to Target file -> Click on Summary -> Supported Device Orientations
Here we can select our expected orientations
Click Portrait to de-select it.
