I have this code, set to make the clockView appear when the phone is rotated to landscape, and then to make it go back to the mainView when it's returned to portrait. But when it does go back to portrait, the portrait view is in landscape mode. How do i fix this? This is my code.
-(void)willAnimateRotationToInterfaceOrientation(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
{
UIInterfaceOrientation toOrientation = self.interfaceOrientation;
if(toOrientation == UIInterfaceOrientationPortrait)
{
self.view = mainView;
}
else if(toOrientation == UIInterfaceOrientationLandscapeLeft)
{
self.view = clockView;
}
else if (toOrientation == UIInterfaceOrientationPortraitUpsideDown)
{
self.view = mainView;
}
else if(toOrientation == UIInterfaceOrientationLandscapeRight)
{
self.view = clockView;
}
}
It is probably better to have both mainView and clockView as subviews of your view controller:
// in viewDidLoad do [self.view addSubView:mainView]; [self.view addSubView:clockView]; clockView.hidden = YES;
-(void)willAnimateRotationToInterfaceOrientation: (UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration {
if(UIInterfaceOrientationIsPortrait(toOrientation)) {
mainView.hidden = NO;
clockView.hidden = YES;
}
else {
mainView.hidden = YES;
clockView.hidden = NO;
}
}
This way, boths views are automatically rotated in the right way and your problem should go away.

I am showing a custom UILabel in my appdelegate class when a push notification comes. It is working fine in Portrait mode but when i rotate my device to landscape mode, label is still showing in Portrait mode. How can i fix it. I have implement rotation method. But it did not worked. Thanks in advance.
My code is :
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
CGRect frame=[[UIApplication sharedApplication] statusBarFrame];
if ([[UIApplication sharedApplication] statusBarOrientation] == UIInterfaceOrientationLandscapeLeft
|| [[UIApplication sharedApplication] statusBarOrientation] == UIInterfaceOrientationLandscapeRight) {
backgroundImageView=[[UILabel alloc] initWithFrame:CGRectMake(0, 0, 480, 32)];
} else {
backgroundImageView=[[UILabel alloc] initWithFrame:CGRectMake(0, frame.size.height, 320, 44)];
NSLog(#"portrait");
}
[backgroundImageView setBackgroundColor:[UIColor colorWithPatternImage:[UIImage imageNamed:#"alert.png"]]];
backgroundImageView.userInteractionEnabled=YES;
UITapGestureRecognizer *tgr = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(click:)];
[backgroundImageView addGestureRecognizer:tgr];
[self.window addSubview:backgroundImageView];
}![enter image description here][1]
I have done the similar kind of thing using the following code...
- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration {
[self adjustUrLableViewForOrientation:toInterfaceOrientation];
}
-(void) adjustUrLableViewForOrientation:(UIInterfaceOrientation)orientation
{
if (orientation == UIInterfaceOrientationPortrait || orientation == UIInterfaceOrientationPortraitUpsideDown)
{
//Ur lable portrait view
}
else if (orientation == UIInterfaceOrientationLandscapeLeft || orientation == UIInterfaceOrientationLandscapeRight)
{
//Ur lable for landscape view
}
}
Also you can look into this changing the lable position based on the orientation.
UiWindow subviews dont rotate by themselves..
you need to check for device rotation changes like this
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(deviceOrientationDidChange:)
name:UIDeviceOrientationDidChangeNotification object:nil];
and then in the method..rotate your label manually based on current orientation.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
return (interfaceOrientation == UIInterfaceOrientationPortrait ||
interfaceOrientation == UIInterfaceOrientationLandscapeLeft ||
interfaceOrientation == UIInterfaceOrientationLandscapeRight ||
interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown );
}
Add this...Hope this helps..
Or add this:
- (BOOL)shouldAutorotate{
return YES;
}
- (NSUInteger)supportedInterfaceOrientations{
return UIInterfaceOrientationPortrait || UIInterfaceOrientationLandscapeLeft || UIInterfaceOrientationLandscapeRight || UIInterfaceOrientationPortraitUpsideDown ;
}
[backgroundImageView setTransform:CGAffineTransformMakeRotation(M_PI/2.0)];
Should work for this case
I am using MBProgressHud to show a loading indicator on a splash view but this does not change with device orientation. My code is:
splashView = [[UIImageView alloc] initWithFrame:self.window.frame];
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
{
splashView.image = [UIImage imageNamed:#"DefaultPad.png"];
}
else
{
splashView.image = [UIImage imageNamed:#"Default.png"];
}
hud = [[MBProgressHUD alloc]initWithView:splashView];
[splashView addSubview:hud];
hud.userInteractionEnabled=NO;
hud.labelText = #"Loading...";
[hud show:YES];
[self.window addSubview:splashView];
[self performSelector:#selector(Load_FirstView) withObject:nil afterDelay:3];
[self.window makeKeyAndVisible];
and I have changed the line in MBProgressHud.m file from
- (void)deviceOrientationDidChange:(NSNotification *)notification {
NSLog(#"in device orientation ");
UIView *superview = self.superview;
if (!superview) {
return;
} else if ([superview isKindOfClass:[UIWindow class]]) { // here changes have done
[self setTransformForCurrentOrientation:YES];
} else {
self.bounds = self.superview.bounds;
[self setNeedsDisplay];
}
}
to:
- (void)deviceOrientationDidChange:(NSNotification *)notification {
NSLog(#"in device orientation ");
UIView *superview = self.superview;
if (!superview) {
return;
} else if ([superview isKindOfClass:[UIImageView class]]) {
[self setTransformForCurrentOrientation:YES];
} else {
self.bounds = self.superview.bounds;
[self setNeedsDisplay];
}
}
How can I get the loading indicator to rotate with device orientation?
In MBProgressHUD.m I changed
UIInterfaceOrientation orientation = [UIApplication sharedApplication].statusBarOrientation;
to
UIInterfaceOrientation orientation = [[UIDevice currentDevice] orientation];
The orientation notification had been received, but the statusBar had not rotated yet.
Try This:-
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
if(interfaceOrientation == UIInterfaceOrientationPortrait || interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown)
{
//code for portrait
[hud release];
hud = [[MBProgressHUD alloc]initWithView:splashView];
}
else
{
//code for Landscape
[hud release];
hud = [[MBProgressHUD alloc]initWithView:splashView];
}
return (interfaceOrientation == UIInterfaceOrientationLandscapeRight ||
interfaceOrientation == UIInterfaceOrientationPortrait ||
interfaceOrientation == UIInterfaceOrientationLandscapeLeft ||
interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown);
}
if it does not work..
you can change the UIDeviceOrientationDidChangeNotification with UIApplicationDidChangeStatusBarOrientationNotificationin the source code of MBProgressHUD:-
- (id)initWithView:(UIView *)view {
// Let's check if the view is nil (this is a common error when using the windw initializer above)
if (!view) {
[NSException raise:#"MBProgressHUDViewIsNillException"
format:#"The view used in the MBProgressHUD initializer is nil."];
}
id me = [self initWithFrame:view.bounds];
// We need to take care of rotation ourselfs if we're adding the HUD to a window
if ([view isKindOfClass:[UIWindow class]]) {
[self setTransformForCurrentOrientation:NO];
}
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(deviceOrientationDidChange:)
name:UIDeviceOrientationDidChangeNotification object:nil];
return me;
}
In the above code change UIDeviceOrientationDidChangeNotificationwith UIApplicationDidChangeStatusBarOrientationNotification.
It is just a work-around as rotation issue was always there with MBProgressHud .
I Guess MBProgressHud is giving a lo of problems , you should instead switch to svprogresshud as it handles orientations well
i have taken two views one is portrait and landscape,i want the switch the view on rotation i am using below code but its not working,may i know where i am going wrong as i am new to iphone development.i have not implemented anything in ViewDidLoad method,should i implement anything there as well?
- (BOOL) shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
if (interfaceOrientation == UIInterfaceOrientationLandscapeLeft || interfaceOrientation == UIInterfaceOrientationLandscapeRight) {
self.portrait.hidden = YES;
self.landscape.hidden = NO;
} else {
self.portrait.hidden = NO;
self.landscape.hidden =YES;
}
return YES;
}
I have showed To Images in Two Views One in Horizontal and one in Vertical....
In ViewController.m:-
#interface OrientationTutorialViewController : UIViewController
{
IBOutlet UIView *portraitView;
IBOutlet UIView *landscapeView;
}
#property (nonatomic, retain) IBOutlet UIView *portraitView;
#property (nonatomic, retain) IBOutlet UIView *landscapeView;
#end
IN .h :-
#implementation OrientationTutorialViewController
#synthesize portraitView, landscapeView;
- (void)viewDidLoad
{
[super viewDidLoad];
[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(orientationChanged:) name:#"UIDeviceOrientationDidChangeNotification" object:nil];
}
- (void) orientationChanged:(id)object
{
UIInterfaceOrientation interfaceOrientation = [[object object] orientation];
if (interfaceOrientation == UIInterfaceOrientationPortrait || interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown)
{
self.view = self.portraitView;
}
else
{
self.view = self.landscapeView;
}
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return YES;
}
- (void)dealloc
{
[super dealloc];
}
#end
Hope My Answer Helps You... If Not Please Tell me ur id I will Send u the Project.
To support orientation the function
-(Bool)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
return YES;
}
Now to perform the action while rotation you have to use the below function
As you have two views named landscape and portrait make sure that you have linked Referencing outlets correctly
-(void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
{
if (toInterfaceOrientation == UIInterfaceOrientationPortrait || toInterfaceOrientation == UIInterfaceOrientationPortraitUpsideDown)
{
self.view = portrait;
}
else
{
self.view = landscape;
}
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
if(interfaceOrientation == UIInterfaceOrientationLandscapeLeft || interfaceOrientation == UIInterfaceOrientationLandscapeRight) {
self.portrait.hidden = YES;
self.landscape.hidden = NO;
return YES;
}
else {
self.portrait.hidden = NO;
self.landscape.hidden = YES;
return YES;
}
}
I have two overlay images that I want show in camera view depending on the device orientation - one for the horizontal and one for vertical orientation (overlay_v.png and overlay_h.png). When device is rotated from portrait to vertical orientation, overlay image should change as well.
With beginGeneratingDeviceOrientationNotifications I am able only to determine the device orientation but cannot manage to change the overlay images. Any help / different approach would be very appreciated.
- (IBAction) getPhoto:(id) sender {
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
if((UIButton *) sender == choosePhotoBtn) {
sourceCamera = false;
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
} else {
sourceCamera = true;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
//overlay image (cannot dynamically switch from vertical to horizontal in here)
UIImageView *anImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"overlay_v.png"]];
anImageView.frame = CGRectMake(0, 0, anImageView.image.size.width, anImageView.image.size.height);
picker.cameraOverlayView = anImageView;
//device orientation check
[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(didOrientation:) name:#"UIDeviceOrientationDidChangeNotification" object:nil];
[anImageView release];
}
[self presentModalViewController:picker animated:YES];
}
- (void) didOrientation: (id)object {
UIInterfaceOrientation interfaceOrientation = [[object object] orientation];
if (interfaceOrientation == UIInterfaceOrientationPortrait || interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown) {
NSLog(#"portrait");
} else if (interfaceOrientation == UIInterfaceOrientationLandscapeRight || interfaceOrientation == UIInterfaceOrientationLandscapeLeft ){
NSLog(#"landscape");
}
}
You can't change the cameraOverlayView property once the picker is displayed. However, you can modify the view itself. Create a UIView property named overlayView. Add both images as subViews to this view and use the tag property on each image to easily grab that view again. Hide the one that shouldn't be shown for the current orientation.
- (void) didOrientation: (id)object {
UIInterfaceOrientation interfaceOrientation = [[object object] orientation];
UIImageView *pImageView = [self.overlayView viewWithTag:10];
UIImageView *lImageView = [self.overlayView viewWithTag:20];
if (interfaceOrientation == UIInterfaceOrientationPortrait ||
interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown) {
NSLog(#"portrait");
pImageView.hidden = NO;
lImageView.hidden = YES;
} else if (interfaceOrientation == UIInterfaceOrientationLandscapeRight ||
interfaceOrientation == UIInterfaceOrientationLandscapeLeft ){
NSLog(#"landscape");
pImageView.hidden = YES;
lImageView.hidden = NO;
}
}
I'm rotating a view similar to tje iTunes app. In portrait is a tableview and in landscape is photo viewver.
When I return from landscape to portrait I try to recover the navigationbar but instead get a distorted tableview, and no navigation bar.
This is what I do:
- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation
duration:(NSTimeInterval)duration {
BOOL restoreNav = NO;
if ((toInterfaceOrientation == UIInterfaceOrientationPortrait) ||
(toInterfaceOrientation == UIInterfaceOrientationPortraitUpsideDown)) {
[self inPortrait];
restoreNav = YES;
} else {
[self inLandscape];
}
if (self.landscape)
{
if (toInterfaceOrientation == UIInterfaceOrientationPortrait)
{
self.view = self.portrait;
}
else if (toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft)
{
self.view = self.landscape;
}
else if (toInterfaceOrientation == UIInterfaceOrientationPortraitUpsideDown)
{
self.view = self.portrait;
}
else if (toInterfaceOrientation == UIInterfaceOrientationLandscapeRight)
{
self.view = self.landscape;
}
[[self.navigationController view] setFrame: [[UIScreen mainScreen] bounds]];
} else {
self.navigationController.navigationBarHidden = NO;
}
[super willRotateToInterfaceOrientation:toInterfaceOrientation duration:duration];
I found a semi-fix for this in http://www.iphonedevsdk.com/forum/iphone-sdk-development/3262-horrible-drawing-after-hiding-navigationbar.html
This is the relevant code:
- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation {
//total hack - to fix the bug where the screen layout is shagged if the device orientation
//is changed when the navigation is hidden
if ([self.navigationController isNavigationBarHidden])
{
[self.navigationController setNavigationBarHidden:NO animated:NO];
[self.navigationController setNavigationBarHidden:TRUE animated:NO];
}
}
However, is messy again if a show up the nav bar.
