Switch View in XIB based on orientation - uiview

Question

I have two views inside my XIB for each orientation. They are similar but different so I cannot rely on the autoresizing. I want to switch these views based on the orientation. When I use the method didRotateFromInterfaceOrientation then when it rotates from Portrait it will show the landscape view, this is a problem when it is rotating to PortraitUpsideDown.
And if I modify the code for willRotateToInterfaceOrientation then in LandscapeView the PortraitView is hidden from the user but when the user clicks the buttons they do not show gray out to show that they were clicked and it app responds as if the user is clicking the buttons that are in the portrait view.
Am I going about this problem in the right manner? What do I need to do to fix these errors. I would prefer to use the method willRotateToInterfaceOrientation.
Thanks,
CODE:
- (void)viewDidLoad {
...
for (UIView *v in self.view.subviews) {
v.autoresizingMask = UIViewAutoresizingNone;
}
...
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
return YES;
}
- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation {
if(fromInterfaceOrientation == UIInterfaceOrientationPortrait
|| fromInterfaceOrientation == UIInterfaceOrientationPortraitUpsideDown) {
//Add landscape view
if(![landscapeView superview]){
for (UIView *v in landscapeView.subviews) {
v.autoresizingMask = UIViewAutoresizingNone;
}
//No effect after testing
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.33];
[self.view addSubview:landscapeView];
[UIView commitAnimations];
}
}else {
if([landscapeView superview]){
[landscapeView removeFromSuperview];
}
}
}
- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
{
if(toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft
|| toInterfaceOrientation == UIInterfaceOrientationLandscapeRight) {
//Add landscape view
if(![landscapeView superview]){
for (UIView *v in landscapeView.subviews) {
v.autoresizingMask = UIViewAutoresizingNone;
}
//No effect after testing
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.33];
[self.view addSubview:landscapeView];
[UIView commitAnimations];
}
}else {
if([landscapeView superview]){
[landscapeView removeFromSuperview];
}
}
}

In Your View Did Load
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(willRotateToInterfaceOrientation:)
name:#"UIDeviceOrientationDidChangeNotification" object:nil];
-(void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration {
if ([[UIDevice currentDevice] orientation] == UIDeviceOrientationLandscapeLeft) {
viewControllerName *newView = [[viewControllerName alloc] initWithNibName:nil bundle:nil];
newView.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
[self presentModalViewController:newView animated:YES];
[newView release];
}
if ([[UIDevice currentDevice] orientation] == UIDeviceOrientationLandscapeRight) {
viewControllerName *newView = [[viewControllerName alloc] initWithNibName:nil bundle:nil];
newView.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
[self presentModalViewController:newView animated:YES];
[newView release];
}
if ([[UIDevice currentDevice] orientation] == UIDeviceOrientationPortrait) {
viewControllerName *newView = [[viewControllerName alloc] initWithNibName:nil bundle:nil];
newView.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
[self presentModalViewController:newView animated:YES];
[newView release];
}
if ([[UIDevice currentDevice] orientation] == UIDeviceOrientationPortraitUpsideDown) {
viewControllerName *newView = [[viewControllerName alloc] initWithNibName:nil bundle:nil];
newView.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
[self presentModalViewController:newView animated:YES];
[newView release];
}
