Load another .xib when orientation in iOS - ios

Question

I used below code to implement that but it not work. Please give me some advices. Thanks much.
-(void)viewWillAppear:(BOOL)animated{
[super viewWillAppear:animated];
self.navigationController.navigationBar.tintColor = [UIColor whiteColor];
[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(orientationChanged:) name:UIDeviceOrientationDidChangeNotification object:nil];
}
orientationChanged() function:
- (void)orientationChanged:(NSNotification *)notification{
[self adjustViewsForOrientation:[[UIApplication sharedApplication] statusBarOrientation]];
}
adjustViewsForOrientation() function:
- (void) adjustViewsForOrientation:(UIInterfaceOrientation) orientation {
if (orientation == UIInterfaceOrientationPortrait || orientation == UIInterfaceOrientationPortraitUpsideDown)
{
NSLog(#"load portrait view");
[[NSBundle mainBundle] loadNibNamed:#"DashBoardViewController" owner:self options:nil];
}
else if (orientation == UIInterfaceOrientationLandscapeLeft || orientation == UIInterfaceOrientationLandscapeRight)
{
NSLog(#"load landscapeview");
[[NSBundle mainBundle] loadNibNamed:#"DashBoardLandscapeView" owner:self options:nil];
}
}
When run it always show DashBoardViewController.xib. In lanscape, it still shows DashBoardViewController.xib. I don't know why.

Answer 1

This is because your not actually setting the view.
You need to do something like:
self.view = [[NSBundle mainBundle] loadNibNamed:#"DashBoardLandscapeView" owner:self options:nil] objectAtIndex:0];
This will load the view from the Xib file, and set the current view to that view.
Don't forget to add the objectAtIndex:0 as you see in the code.

Answer 2

Use willRotateToInterfaceOrientation: method instead of notifications
-(void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
{
if( UIInterfaceOrientationIsLandscape(toInterfaceOrientation) )
{
NSLog(#"load landscapeview");
[[NSBundle mainBundle] loadNibNamed:#"DashBoardLandscapeView" owner:self options:nil];
//[self viewDidLoad];
}
else
{
NSLog(#"load portrait view");
[[NSBundle mainBundle] loadNibNamed:#"DashBoardViewController" owner:self options:nil];
//[self viewDidLoad];
}
}
Maybe you have to uncoment [self viewDidLoad] if you have som logic there.
