here i need only popup rotation .Any Ref link or suggestion ,it's really appreciated.
Return NO from
- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
Handle device rotation via Local Notifications :-
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(didRotate:)
name:UIDeviceOrientationDidChangeNotification
object:nil];
And rotate the view as you want :-
self.theView.transform = CGAffineTransformIdentity;
self.theView.transform = CGAffineTransformMakeRotation(degreesToRadians(-90));
May this help you.
Please register for rotation notifications in viewdidlod
(void)viewDidLoad
{
UIInterfaceOrientation currentOrientation = [[UIApplication sharedApplication] statusBarOrientation];
if (currentOrientation == UIInterfaceOrientationLandscapeLeft || currentOrientation == UIInterfaceOrientationLandscapeRight)
[self willRotateToLandscape];
else
[self willRotateToPortrait];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(willRotateToLandscape) name:#"Interface will rotate to landscape" object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(willRotateToPortrait) name:#"Interface will rotate to portrait" object:nil];
}
//then adjust the popup view size in the following functions.
- (void)willRotateToLandscape
{
}
- (void)willRotateToPortrait

At first, sorry for my bad English, I'm just learning it. Im relatively new at Objective-C and I'm using FBConnect bundle to link my app to Facebook. All it's working correctly, but when I click a link into the UIWebView (the Facebook login button, for example), my UIWebView gets fullscreen and hides my close button (a little 'x' button in the top right of the UIWebView, called here "_closeButton").
Here's the code:
The "init" method:
- (id)init {
if ((self = [super initWithFrame:CGRectZero])) {
_delegate = nil;
_loadingURL = nil;
_showingKeyboard = NO;
self.backgroundColor = [UIColor clearColor];
self.autoresizesSubviews = NO;
//self.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
self.contentMode = UIViewContentModeRedraw;
_webView = [[UIWebView alloc] initWithFrame:CGRectMake(kPadding, kPadding, 480, 480)];
_webView.delegate = self;
//_webView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
[self addSubview:_webView];
//UIImage* closeImage = [UIImage imageNamed:#"FBDialog.bundle/images/close.png"];
UIImage* closeImage = [UIImage imageNamed:#"close"];
UIColor* color = [UIColor colorWithRed:255.0/255 green:/*184.0*/0.0/255 blue:/*216.0*/0.0/255 alpha:1];
_closeButton = [[UIButton buttonWithType:UIButtonTypeCustom] retain];
[_closeButton setImage:closeImage forState:UIControlStateNormal];
[_closeButton setTitleColor:color forState:UIControlStateNormal];
[_closeButton setTitleColor:[UIColor whiteColor] forState:UIControlStateHighlighted];
[_closeButton addTarget:self action:#selector(cancel)
forControlEvents:UIControlEventTouchUpInside];
// To be compatible with OS 2.x
#if __IPHONE_OS_VERSION_MAX_ALLOWED <= __IPHONE_2_2
_closeButton.font = [UIFont boldSystemFontOfSize:12];
#else
_closeButton.titleLabel.font = [UIFont boldSystemFontOfSize:12];
#endif
_closeButton.showsTouchWhenHighlighted = YES;
_closeButton.autoresizingMask = UIViewAutoresizingFlexibleRightMargin
| UIViewAutoresizingFlexibleBottomMargin;
[self addSubview:_closeButton];
NSLog(#"close");
_spinner = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:
UIActivityIndicatorViewStyleWhiteLarge];
_spinner.autoresizingMask =
UIViewAutoresizingFlexibleTopMargin | UIViewAutoresizingFlexibleBottomMargin
| UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin;
[self addSubview:_spinner];
_modalBackgroundView = [[UIView alloc] init];
}
return self;
}
The delegate of the WebView (I suspect here's where I need to do the trick)
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request
navigationType:(UIWebViewNavigationType)navigationType {
NSURL* url = request.URL;
if ([url.scheme isEqualToString:#"fbconnect"]) {
if ([[url.resourceSpecifier substringToIndex:8] isEqualToString:#"//cancel"]) {
NSString * errorCode = [self getStringFromUrl:[url absoluteString] needle:#"error_code="];
NSString * errorStr = [self getStringFromUrl:[url absoluteString] needle:#"error_msg="];
if (errorCode) {
NSDictionary * errorData = [NSDictionary dictionaryWithObject:errorStr forKey:#"error_msg"];
NSError * error = [NSError errorWithDomain:#"facebookErrDomain"
code:[errorCode intValue]
userInfo:errorData];
[self dismissWithError:error animated:YES];
} else {
[self dialogDidCancel:url];
}
} else {
[self dialogDidSucceed:url];
}
return NO;
} else if ([_loadingURL isEqual:url]) {
return YES;
} else if (navigationType == UIWebViewNavigationTypeLinkClicked) {
if ([_delegate respondsToSelector:#selector(dialog:shouldOpenURLInExternalBrowser:)]) {
if (![_delegate dialog:self shouldOpenURLInExternalBrowser:url]) {
return NO;
}
}
[[UIApplication sharedApplication] openURL:request.URL];
return NO;
} else {
return YES;
}
}
And the show method (called when I need to show the Web View)
- (void)show {
NSLog(#"Cuantas veces me ves?");
[self load];
[self sizeToFitOrientation:NO];
CGFloat innerWidth = self.frame.size.width - (kBorderWidth+1)*2;
[_closeButton sizeToFit];
_closeButton.frame = CGRectMake(
2,
2,
29,
29);
_webView.frame = CGRectMake(
kBorderWidth+1,
kBorderWidth+1,
innerWidth,
self.frame.size.height - (1 + kBorderWidth*2));
[_spinner sizeToFit];
[_spinner startAnimating];
_spinner.center = _webView.center;
UIWindow* window = [UIApplication sharedApplication].keyWindow;
if (!window) {
window = [[UIApplication sharedApplication].windows objectAtIndex:0];
}
_modalBackgroundView.frame = window.frame;
[_modalBackgroundView addSubview:self];
[window addSubview:_modalBackgroundView];
[window addSubview:self];
[self dialogWillAppear];
self.transform = CGAffineTransformScale([self transformForOrientation], 0.001, 0.001);
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:kTransitionDuration/1.5];
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:#selector(bounce1AnimationStopped)];
self.transform = CGAffineTransformScale([self transformForOrientation], 1.1, 1.1);
[UIView commitAnimations];
[self addObservers];
}
Googling the problem, I found that this could be the Default behaviour of the UIWebView. How can I change it to make all my WebViews of the same size than the first one?
Thanks in advance!
== EDIT ==
Still don't know why is my UIWebView acting like this, or how to solve it, but since the code is part of the FBConnect Bundle, I suppose I shouldn't edit it too much. I just created programmatically a new close button on the top and that's all. But I'll let the question open if someone knows how to solve it. Thanks to Leo Natan for his help.
I am creating a app that display subview like ActionSheetView and in that i have added UIGridView and UIPageControll thru outlet , but now when i click the cell it does not respond ,my subview is a ViewController with the nib file.
and if i create a button and add in my popupview programmatically then it wil displaying, and also get the click event, but anything in outlet does not respond.
i have tried to set userinteraction enable in my subview but it does not done any good.
here is my code for first view that display subview by clicking barbutton:
- (void)popUpView:(id)sender {
//self.view.backgroundColor = [UIColor darkGrayColor];
bGView = [[UIView alloc] init]; /this is the background view and all view is added in it
bGView.frame = CGRectMake(0,0,320,490);
bGView.backgroundColor = [UIColor clearColor];
bGView.alpha = 0.8 ;
CGRect viewFrame = CGRectMake(10, 90, 300, 300);
aPopUpViewController = [[PopUpViewController alloc] initWithNibName:#"PopUpViewController" bundle:nil]; //this is my view controller and when this shows on screen it display my greed view
aPopUpViewController.view.frame = viewFrame;
aPopUpViewController.view.userInteractionEnabled = YES;
[bGView addSubview:aPopUpViewController.view];
button = [UIButton buttonWithType:UIButtonTypeCustom];
[button addTarget:self
action:#selector(aMethod:)
forControlEvents:UIControlEventTouchDown];
button.backgroundColor = [UIColor clearColor];
[button setBackgroundImage:[UIImage imageNamed:#"close_button.png"] forState:UIControlStateNormal];
button.frame = CGRectMake(-1, 80, 30, 30);
[bGView addSubview:button];
//for view animation
/*
// from bottom to center animation
[bGView setFrame:CGRectMake( 0.0f, 480.0f, 320.0f, 480.0f)]; //notice this is OFF screen!
[UIView beginAnimations:#"animateTableView" context:nil];
[UIView setAnimationDuration:0.4];
[bGView setFrame:CGRectMake( 0.0f, 0.0f, 320.0f, 480.0f)]; //notice this is ON screen!
[UIView commitAnimations];*/
//for page like effect
/*[UIView transitionWithView:self.view duration:0.5
options:UIViewAnimationOptionTransitionCurlUp //change to whatever animation you like
animations:^ { [self.view addSubview:bGView]; }
completion:nil];*/
/*CATransition *transition = [CATransition animation];
transition.duration = 1.0;
transition.type = kCATransitionReveal; //choose your animation
[bGView.layer addAnimation:transition forKey:nil];
[self.view addSubview:bGView];*/
aPopUpViewController.view.userInteractionEnabled = YES;
bGView.userInteractionEnabled = YES;
self.view.userInteractionEnabled = YES;
bGView.transform = CGAffineTransformMakeScale(0.01, 0.01);
[UIView animateWithDuration:0.2 delay:0 options:UIViewAnimationOptionCurveEaseOut animations:^{
bGView.transform = CGAffineTransformIdentity;
} completion:^(BOOL finished){
// do something once the animation finishes, put it here
}];
[self.view addSubview:bGView];
addLabel.enabled = NO;
clipArt.enabled = NO;
emailItem.enabled = NO;
closeButton.enabled = NO;
self.navigationController.topViewController.title = #"Choose ClipArt";
ExampleAppDataObject* theDataObject = [self theAppDataObject];
theDataObject.navBarHide = #"no";
}
- (void)aMethod:(id)sender
{
//[aPopUpViewController.view removeFromSuperview];
//[button removeFromSuperview];
/*[UIView transitionWithView:self.view duration:0.5
options:UIViewAnimationOptionTransitionCrossDissolve//change to whatever animation you like
animations:^ { [bGView removeFromSuperview]; }
completion:nil];*/
[bGView removeFromSuperview];
addLabel.enabled = YES;
clipArt.enabled = YES;
emailItem.enabled = YES;
closeButton.enabled = YES;
self.navigationController.topViewController.title = #"Greeting's";
ExampleAppDataObject* theDataObject = [self theAppDataObject];
theDataObject.navBarHide = #"yes";
}
and this is how my screen look like
UPDATE
now i figured out my problem,problem is that i have given my whole view a tap listner,now i am adding grid view as subview so when ever i tap on cell rather then do select cell it will generate view tap gesture and thats why cell never selected,that's what i think..
add this line after you add every subviews in your main view..
[self.view bringSubviewToFront:yourGridView];
I have a UIView,with a subview of a UISCrollView with a subview of a view(lastView). What I wanted is when I long press the view it will remove the lastView. then after a long press again the lastView will appear again. I tried it, but I only got this far. My lastView isnt appearing and my long press gesture isnt working too.
Here is my code:
- (void)handleLongPress:(UILongPressGestureRecognizer*)sender {
if (sender.state == UIGestureRecognizerStateEnded) {
[self.slotView removeFromSuperview];
NSLog(#"Long press Ended");
}
else {
NSLog(#"Long press detected.");
}
}
- (void) createScrollView {
self.slotBg = [[UIView alloc] initWithFrame:CGRectMake(43, 370, 300, 143)];
CAGradientLayer *gradient = [CAGradientLayer layer];
gradient.frame = self.slotBg.bounds;
gradient.colors = [NSArray arrayWithObjects:(id)[[UIColor grayColor] CGColor], (id)[[UIColor whiteColor] CGColor], nil];
[self.slotBg.layer insertSublayer:gradient atIndex:0];
[self.view addSubview:self.slotBg];
UILongPressGestureRecognizer *longPress =
[[UILongPressGestureRecognizer alloc] initWithTarget:self
action:#selector(handleLongPress:)];
longPress.minimumPressDuration = 2.0;
[slotBg addGestureRecognizer:longPress];
UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0.0f,0.0f,300.0f,134.0f)];
[slotBg addSubview:scrollView];
self.slotView = [[UIView alloc] initWithFrame:CGRectMake(0.0f,0.0f,300.0f,134.0f)];
[scrollView addSubview:slotView];
int row = 0;
int column = 0;
for(int i = 0; i < _thumbs.count; ++i) {
UIImage *thumb = [_thumbs objectAtIndex:i];
UIButton * button = [UIButton buttonWithType:UIButtonTypeCustom];
button.frame = CGRectMake(column*60+10, row*60+10, 60, 60);
[button setImage:thumb forState:UIControlStateNormal];
[button addTarget:self
action:#selector(buttonClicked:)
forControlEvents:UIControlEventTouchUpInside];
button.tag = i;
[scrollView addSubview:button];
if (column == 4) {
column = 0;
row++;
} else {
column++;
}
}
[scrollView setContentSize:CGSizeMake(330, (row+1) * 60 + 10)];
}
In view's touchesBegan: you can call your "long tap" handle with some delay.
[touchHandler performSelector:#selector(longTap:) withObject:nil afterDelay:1.5];
Then in view's touchesEnded: you can cancel that call if not enough time has passed:
[NSObject cancelPreviousPerformRequestsWithTarget:touchHandler selector:#selector(longTap:) object:nil];
Add bool *flag in .h file of view; and in viewDid load add this flag = true;
Now selector longTap: would be:
-(void)longTap:(id)sender
{
if(flag){
flag = false;
[lastView removeFromSuperView];
}
else{
flag = true;
//Create lastView reference
[scrollView addSubView:lastView];
}
}
Add UIGestureRecognizerDelegate and write [longPress setDelegate:self]; in - (void) createScrollView. I think it will helpful to you.
I'm doing a bit of AR work here and one of the biggest problem right now is one of my UIView will not respond to any frame settings I make to it.
The code is very similar to this. I've made a few major changes to incorporate into my project:
nurse.site11.com/JaredCrawford-iWVU-632a9a0/Libraries/ARKit/AugmentedRealityController.m
"displayView" is used as a custom UIView that is passed to UIImagePickerController's setCameraOverlayView: method.
Now in the initWithViewController method of that AugmentedRealityController.m file, I have tried setting the displayView = [[UIView alloc] initWithFrame:CGRectMakeFrame(0, 0, 480, 320)];
The problem is, even if I set it to displayView = [[UIView alloc] initWithFrame:CGRectMakeFrame(0, 0, 100, 100)]; the view still remains full screen 320 x 480 BUT only for the first time the Augmented Reality view appeared. Subsequent times that the AR view appears, the code works.
I am not sure what the heck is going on and why setting the frame of the displayView not affecting the view at all FOR THE FIRST TIME it is shown.
I'm hoping someone else has experienced this problem before and possibly solved it.
This is my code:
- (id)initWithViewController:(UIViewController *)vc
{
coordinates = [[NSMutableArray alloc] init];
coordinateViews = [[NSMutableArray alloc] init];
latestHeading = -1.0f;
debugView = nil;
[self setRootViewController: vc];
[self setDebugMode:NO];
[self setMaximumScaleDistance: 0.0];
[self setMinimumScaleFactor: 1.0];
[self setScaleViewsBasedOnDistance: YES];
[self setRotateViewsBasedOnPerspective: YES];
[self setMaximumRotationAngle: M_PI / 6.0];
//CGRect screenRect = [[UIScreen mainScreen] bounds];
NSLog(#"inside initWithViewController");
UIDeviceOrientation orientation = [[UIDevice currentDevice] orientation];
if(orientation == UIDeviceOrientationPortrait)
{
NSLog(#"Orientation portrait");
}
else if(orientation == UIDeviceOrientationLandscapeRight)
{
NSLog(#"orientation right");
[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeLeft];
[self setCurrentOrientation:UIDeviceOrientationLandscapeRight];
}
else if(orientation == UIDeviceOrientationPortraitUpsideDown)
{
NSLog(#"orientation upsidedown");
}
else if(orientation == UIDeviceOrientationLandscapeLeft){
NSLog(#"orientation left");
[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeRight];
[self setCurrentOrientation:UIDeviceOrientationLandscapeLeft];
}
//[[UIApplication sharedApplication] setStatusBarOrientation:UIInterfaceOrientationLandscapeLeft];
//NSLog(#"In AR view, device orientation = %#", [[UIDevice currentDevice] orientation]);
//[self setDisplayView: [[UIView alloc] initWithFrame: screenRect]];
//[self setCurrentOrientation:UIDeviceOrientationLandscapeRight];
displayView = [[UIView alloc] initWithFrame:CGRectMake(-80, 80, 480, 320)];
[displayView setBackgroundColor:[UIColor colorWithRed:0.0 green:0.0 blue:1.0 alpha:0.5]];
NSLog(#"displayView x = %f", displayView.frame.origin.x);
NSLog(#"displayView y = %f", displayView.frame.origin.y);
NSLog(#"displayView width = %f", displayView.frame.size.width);
NSLog(#"displayView height = %f", displayView.frame.size.height);
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(deviceOrientationDidChange:) name: UIDeviceOrientationDidChangeNotification object:nil];
[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
[[self rootViewController] setView:displayView];
//[[self rootViewController] setView:[[UIView alloc] initWithFrame:CGRectMake(0, 0, 480, 320)]];
//[[rootViewController view] setBackgroundColor:[UIColor blueColor]];
CLLocation *newCenter = [[CLLocation alloc] initWithLatitude:37.41711 longitude:-122.02528];
[self setCenterLocation: newCenter];
[newCenter release];
[self startListening];
[self deviceOrientationUpdate];
startLocation = nil;
i = 0;
objImageView = [[UIImageView alloc] initWithFrame:CGRectMake(0,0,320,480)];
//[objImageView setBackgroundColor:[UIColor blueColor]];
blnHasRotated = NO;
return self;

I have a UIViewController that I'm using to control a "pop-up" view for viewing images throughout my application. It supports autorotation, as it automatically sizes the image to fit properly regardless of orientation. This works perfectly, but only the first time I initialize and display the view controller. When it closes, I am removing the UIView from my view hierarchy and releasing the view controller - but the next time I instantiate and add it to my view hierarchy, it stops receiving the -shouldAutorotateToInterfaceOrientation messages when the phone is rotated.
This is how I instantiate and display it:
popupVC = [[PopupVC alloc] init];
[popupVC viewWillAppear:NO];
[[[UIApplication sharedApplication] keyWindow] addSubview:popupVC.view];
[popupVC viewDidAppear:NO];
this is how I remove/release it when it's finished:
[popupVC viewWillDisappear:NO];
[popupVC.view removeFromSuperview];
[popupVC viewDidDisappear:NO];
[popupVC release];
popupVC = nil;
I've tried looping through [[UIApplication sharedApplication] keyWindow] subviews to see if somehow my popup view isn't on top, but it always is. And it has a different address each time so I do know that it's a different instance of the view controller class.
As requested, here is the complete loadView method from PopupVC:
- (void)loadView {
UIView *myView = [[UIView alloc] initWithFrame:[UIScreen mainScreen].applicationFrame];
myView.backgroundColor = self.overlayColor;
myView.autoresizesSubviews = NO;
myView.hidden = YES;
myView.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth;
self.view = myView;
[myView release];
_isVisible = NO;
UIView *myMaskView = [[UIView alloc] initWithFrame:self.view.bounds];
myMaskView.backgroundColor = [UIColor clearColor];
myMaskView.clipsToBounds = YES;
myMaskView.hidden = YES;
myMaskView.autoresizesSubviews = NO;
myMaskView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
[self.view addSubview:myMaskView];
self.imageMaskView = myMaskView;
[myMaskView release];
UIImageView *myImageView = [[UIImageView alloc] initWithFrame:CGRectZero];
myImageView.center = self.view.center;
myImageView.hidden = NO;
myImageView.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleHeight;
[self.imageMaskView addSubview:myImageView];
self.imageView = myImageView;
[myImageView release];
UIButton *myImageButton = [UIButton buttonWithType:UIButtonTypeCustom];
myImageButton.frame = self.view.frame;
myImageButton.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleHeight;
[myImageButton addTarget:self action:#selector(clickImage:) forControlEvents:UIControlEventTouchUpInside];
[self.imageMaskView addSubview:myImageButton];
self.imageButton = myImageButton;
UIActivityIndicatorView *myActivityView = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];
myActivityView.hidden = YES;
[self.view addSubview:myActivityView];
myActivityView.center = self.view.center;
self.activityView = myActivityView;
[myActivityView release];
}
The shouldAutorotateToInterfaceOrientation handler isn't the place for custom code to respond to rotation events. It's purpose is just to tell the OS that your view controller can rotate. If you want to have custom code to handle the rotation events you should overide - didRotateFromInterfaceOrientation or one of the other similar callback methods depending on your needs:
willRotateToInterfaceOrientation:duration:
willAnimateRotationToInterfaceOrientation:duration:
didRotateFromInterfaceOrientation:
willAnimateFirstHalfOfRotationToInterfaceOrientation:duration:
didAnimateFirstHalfOfRotationToInterfaceOrientation:
willAnimateSecondHalfOfRotationFromInterfaceOrientation:duration:
See Autorotating Views in the developer docs.
I think that might be a bug in the new OS 3.0. A workaround to this would be to use NSNotificationCenter after turning on beginGeneratingDeviceOrientationNotifications.
- (void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(receivedRotate:) name:UIDeviceOrientationDidChangeNotification object:nil];
}
-(void) receivedRotate: (NSNotification *) notification {
DebugLog(#"ORIENTATION CHANGE");
UIDeviceOrientation interfaceOrientation = [[UIDevice currentDevice] orientation];
if(interfaceOrientation == UIDeviceOrientationPortrait) {
self.view.transform = CGAffineTransformMakeRotation(degreesToRadian(0));
self.view.bounds = CGRectMake(0, 0, 320, 480);
}
else if(interfaceOrientation == UIDeviceOrientationLandscapeLeft) {
self.view.transform = CGAffineTransformMakeRotation(degreesToRadian(90));
self.view.bounds = CGRectMake(0, 0, 480, 320);
}
else if(interfaceOrientation == UIDeviceOrientationLandscapeRight) {
self.view.transform = CGAffineTransformMakeRotation(degreesToRadian(-90));
self.view.bounds = CGRectMake(0, 0, 480, 320);
}
}
My problem is that I get the rotation event for my rootViewController, but as soon as I launch my second viewController, it won't get any signals except motion (shaking) and touch. Is that the same issue as the original post -- it is certainly similiar??
I followed-up with above recommendation and I don't have the selector coded correctly so it throws an exception as soon as I try to rotate. Meanwhile, I found this other discussion on the web which confirms that the problem was introduced in 3.0.
