I use the following code in my app when user click on a button :
[self.navigationController setNavigationBarHidden:NO animated:YES];
The appearance animates normally on iPhone but not on iPad. Do you know why ?
The best solution here may be to put self.navigationBar.hidden = NO; in the -viewWillAppear: method of the UIViewController where you dont wish to have the bar perpetually hidden.
EDIT:
i found this, may help you;
if( UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad )
{
CGRect rect = self.navigationController.navigationBar.frame;
rect.origin.y = rect.origin.y < 0 ?
rect.origin.y + rect.size.height
: rect.origin.y - rect.size.height;
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.2];
self.navigationController.navigationBar.frame = rect;
[UIView commitAnimations];
}
else
{
[self.navigationController setNavigationBarHidden:shouldHide animated:YES];
}
Are you sure you're invoking this in the context of the Main Thread ?
Do check the other code you have written along with the properties of your view. I use this fragment in my universal apps and it works fine on both the iPhone and iPad. So looks like some other setting (probably autosizing properties??) of your views are causing this.
This code is working fine for me. I try with navigation templete for iphone and then that project upgrade for the ipad for two specific device. and run in ipad. Then navigation bar is hide/show with same animation like iphone app does.
try this. May you get more idea.
Thanks,

I'm having a problem with FBDialog.
Apparently after the either the email or the password textFields become first responders and keyboard comes up, the FBDialog view no longer reacts to changing the interface orientation.
Except for the case when keyboard is up, all works as expected.
Did anyone ever encounter this behavior?
Thanks in advance, Vlad
Try this:
(void)deviceOrientationDidChange:(void*)object
{
UIDeviceOrientation orientation = (UIDeviceOrientation)[UIApplication sharedApplication].statusBarOrientation;
if ([self shouldRotateToOrientation:orientation])
{
[self updateWebOrientation];
CGFloat duration = [UIApplication sharedApplication].statusBarOrientationAnimationDuration;
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:duration];
[self sizeToFitOrientation:YES];
[UIView commitAnimations];
}
}
I am working on an iPhone Application and am attempting to get a Landscape View for a simple, editable UITextView working.
Both interface layouts are specified in NIB files, and I have succeeded in loading them and migrating data when the devices rotates.
However, the UITextView in the Landscape version "runs away" from the iPhone Keyboard, making it impossible to see what you're editing. I have no idea why it is doing this--can anybody help?
Thanks in Advance!

No way to know what you are doing without some code, but you should try something like this:
- (void) animateTextField: (UITextView*) textView up: (BOOL) up
{
const int movementDistance = 80; // tweak as needed
const float movementDuration = 0.3f; // tweak as needed
int movement = (up ? -movementDistance : movementDistance);
[UIView beginAnimations: #"anim" context: nil];
[UIView setAnimationBeginsFromCurrentState: YES];
[UIView setAnimationDuration: movementDuration];
self.view.frame = CGRectOffset(self.view.frame, 0, movement);
[UIView commitAnimations];
}
Call this from where you think appropiate (UIKeyboardWillShowNotigication, for instance) and well, it will animate your view in order to show the textview.
following situation.
i have an app that uses a UINavigationController for navigating.
For a push of a special Navigation Controller i want a custom Animation, a zoom out.
What i have is looking good so far, the only problem is, that the "old" Viewcontroller disappears before the animation starts, so the new viewcontroller zooms out of "nothing" instead of viewing the old viewcontroller in the background.
For better viewing i created a simple sample app: download
Does anybody know, how to animate the new viewcontroller (image3) that the old view controller(image1) stays in the background while animating (image 2)?
/* THIS CANNOT BE CHANGED */
AnimatedViewController *animatedViewController = [[AnimatedViewController alloc] initWithNibName:#"AnimatedViewController" bundle:nil];
/* THIS CAN BE CHANGED */
animatedViewController.view.transform = CGAffineTransformMakeScale(0.01, 0.01);
[UIView beginAnimations:#"animationExpand" context:NULL];
[UIView setAnimationDuration:0.6f];
animatedViewController.view.transform=CGAffineTransformMakeScale(1, 1);
[UIView setAnimationDelegate:self];
[UIView commitAnimations];
/* THIS CANNOT BE CHANGED */
[self.navigationController pushViewController:animatedViewController animated:NO];
Additional information: my app isn't that simple. i use three20 framework for my app but the pushing and creating of the view controllers is simply what three20 does. i only can hook into the part between (THIS CAN BE CHANGED in my code). i cannot change the code before and after this (except with a lot of researching).
I whipped this up very quickly. The idea is to call pushViewController after the scale animation is completed.
-(IBAction)animateButtonClicked:(id)sender {
animatedViewController = [[AnimatedViewController alloc] initWithNibName:#"AnimatedViewController" bundle:nil];
animatedViewController.view.transform = CGAffineTransformMakeScale(0.01, 0.01);
[UIView animateWithDuration:0.6
animations:^{
[self.view addSubview:animatedViewController.view];
animatedViewController.view.transform=CGAffineTransformMakeScale(1, 1);
}
completion:^(BOOL finished){
[animatedViewController.view removeFromSuperview];
[self.navigationController pushViewController:animatedViewController animated:NO];
}];
}
Ok, one way to do this (a bit ugly) is to do the animation and upon the completion of the animation, do the pushViewController. When you do the animation, you need to animate up what the about-to-be-presented view controller's screen would look like. Since the animation ends with the new view, when the new view comes to the screen, nothing should change because its the same as the just animated view.
I have an iAd which displays at the top of a fullscreen subview of the main view. The iAd works normally in portrait mode, and I have handled rotation of the iAd banner view into landscape mode. The issue occurs when the iAd is tapped by the user in landscape mode. The test advertisement displays in portrait, sideways on the phone, and when the user taps the x to dismiss the iAd, the banner view and its parent view are pushed offscreen. The iAd behaves normally in portrait mode (i.e. tapping it and closing it results in the view containing the banner to be displayed normally).
Things I have tried:
- (void)bannerViewActionDidFinish:(ADBannerView *)banner{
NSLog(#"Ad was closed, show the adView again");
if(UIInterfaceOrientationIsLandscape(currentInterfaceOrientation)){
[self animateRotationToLandscape:0.3f];
}
else{
[self animateRotationToPortrait:0.3f];
}
}
-(void)animateRotationToPortrait:(NSTimeInterval)duration{
self.adView.currentContentSizeIdentifier =
ADBannerContentSizeIdentifierPortrait;
BOOL iPad = NO;
#ifdef UI_USER_INTERFACE_IDIOM
iPad = (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad);
#endif
if (iPad) {
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:duration];
proUpgradeDescription.frame = CGRectMake(82,313,604,110);
proUpgradePrice.frame = CGRectMake(313,576,142,28);
closeButton.frame = CGRectMake(348,834,72,37);
purchaseButton.frame = CGRectMake(313,431,142,142);
[UIView commitAnimations];
}
else{
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:duration];
proUpgradeDescription.frame = CGRectMake(20,80,280,70);
proUpgradePrice.frame = CGRectMake(88,322,142,28);
closeButton.frame = CGRectMake(123,403,72,37);
purchaseButton.frame = CGRectMake(88,172,142,142);
[UIView commitAnimations];
}
}
Which calls code that I use to animate rotation of the display for portrait and landscape mode. This code has no effect.
If anyone has any ideas as to why the test advertisements don't rotate correctly and why they push the parent view controller off the screen I would greatly appreciate it.
I don't know if this addresses all of your problems, but according to the answer on this question, the test ads are only in portrait, and real ads will show up in both orientations.
I know the question is a little old so I'm posting here just in case someone runs into the same problem (I did).
ADBannerView messes with the frame and transform properties of the parent view so all you have to do is to reset them to their original values after it has finished (in bannerViewActionDidFinish:).
I still don't understand why it doesn't put back everything the way it was after it has finished. We shouldn't have to do this.
This drove me nuts too. Delivering only landscape full page ads to the iPad and portrait to the iPhone and not saying so is asking for trouble. I gave up using the iAdSuite code, which caused the Landscape iPad ad to leave the screen in Landscape even when the device was in portrait!
This is my code for banner ads. It is all in the first view controller loaded. It aims to put the banner at the bottom of the screen.
In the header file:
#import "iAd/ADBannerView.h"
#property (strong, nonatomic) ADBannerView* adView;
#interface myViewController : UIViewController <ADBannerViewDelegate,
in viewDidLoad
CGRect contentFrame = self.view.bounds;
CGRect bannerFrame = CGRectZero;
bannerFrame.size = [adView sizeThatFits:contentFrame.size];
bannerFrame.origin.y = contentFrame.size.height-bannerFrame.size.height;
adView = [[ADBannerView alloc] initWithFrame:bannerFrame];
[adView setDelegate:self];
[self.view addSubview:adView];
Then
-(void)viewWillLayoutSubviews {
CGRect contentFrame = self.view.bounds;
CGRect bannerFrame=CGRectZero;
bannerFrame.size = [adView sizeThatFits:contentFrame.size];
if (adView.bannerLoaded) {bannerFrame.origin.y = contentFrame.size.height-bannerFrame.size.height;}
else {bannerFrame.origin.y = contentFrame.size.height;}
[adView setFrame:bannerFrame];}
Then to handle the callbacks from iAd we need to tell the view to redo its layout if something changes:
- (void)bannerViewDidLoadAd:(ADBannerView *)banner{
[UIView animateWithDuration:0.25 animations:^{
[self.view setNeedsLayout];
[self.view layoutIfNeeded];
}];}
- (void)bannerView:(ADBannerView *)banner didFailToReceiveAdWithError:(NSError *)error{
[UIView animateWithDuration:0.25 animations:^{
[self.view setNeedsLayout];
[self.view layoutIfNeeded];
}];}
This seems to handle the orientation correctly on both iPad and iPhone except for the test full page ads. However, the screen assume correct orientation after the test ad is dismissed so I am hoping it is all OK.
I just upgraded my iPhone 4 from iOS 4.2.1 to 4.3.2, and to XCode 4.0.2, and I am encountering some bizarre issues with uiview animations. When I first launch my app, code like this executes perfectly:
[UIView beginAnimations:#"fadeAlphaIn" context:nil];
[UIView setAnimationDuration:0.5f];
viewClue.alpha = 1.0f;
[UIView commitAnimations];
But then, after dismissing a presenting and then dismissing a modal view by the standard method:
[self presentModalViewController:more animated:YES];
and
[self dismissModalViewControllerAnimated:YES];
the first animation no longer works. Instead of fading in, for example, the viewClue view simply jumps from alpha = 0 to alpha = 1. Similarly, other animations altering other views' frame property just force the frame to jump from the initial to final value without animation. These animations worked fine before the modal view was presented and dismissed.
I understand that others have experienced animation issues with the upgrade to iOS 4.3.2, but the way the modal view disrupts animation seems very odd. Has anyone else experienced this problem? Any ideas as to a solution? I'm thinking of just adding the modal view as a subview and animation it as it hides and appears, but using the standard modal view method would be much preferred.
Thanks for your help,
James
EDIT: Some more code showing how the app's map is animated
-(void) viewMapfunc
{
AudioServicesPlaySystemSound(soundID);
if(mapvisible){
[UIView animateWithDuration:0.5
delay:0.1
options:UIViewAnimationOptionAllowUserInteraction
animations:^{
map.frame = CGRectMake(0, 350, 320, 27);
mapscroll.frame = CGRectMake(0, 27, 320, 0);
}
completion:nil];
mapvisible = NO;
viewMapLabel.text = #"View Map";
}else {
[UIView animateWithDuration:0.5
delay:0.1
options:UIViewAnimationOptionAllowUserInteraction
animations:^{
map.frame = CGRectMake(0, 50, 320, 300);
mapscroll.frame = CGRectMake(0, 27, 320, 300);
}
completion:nil];
mapvisible = YES;
viewMapLabel.text = #"Hide Map";
}
}
Try to check two things:
Do you commit all started animations? I got all kinds of strange effects after not committing one of them.
Do any animations take place in the same time? Especially with the same view.
Whether any animations take place right after changing properties. Something like:
-
view.alpha = 1;
[UIView beginAnimations:…];
view.alpha = 0;
[UIView commitAnimations:…];
In this example, view will not change it's alpha value from 1 to 0. It will change it instantly. To start an animation you have to extract animations block to another method and call it with performSelectorInMainThread:withObject:afterDelay:. Delay can be even 0.
I solved it by restarting my animation in my UIView subclass:
override func willMove(toWindow newWindow: UIWindow?) {
if newWindow != nil {
spinner.startSpinning() // Restart any animation here
}
}
In the end, I just removed all modal views and implemented them in other ways. For some reason, using modal views messed up animations. Makes no sense, but removing them fixed the problem. If anyone can enlighten me as to why this is going on, it might be nice for memory concerns...
I had the same issue. The root of my trouble was that my animation was being triggered by a notification, and I was adding an observer on each viewWillAppear, but forgot to remove in viewDidDisappear (remember that iOS 6 no longer calls viewDidUnload reliably).
Essentially, I was calling my animation function twice in quick succession, which was causing the visible irregularity. Hopefully this helps someone out down the line!
I've managed to solve this same issue in my own application.
I noticed while debugging that my UIImageViews which I was animating had different memory addresses before and after I pushed my modal view controller(s). At no other time did these UIImageViews switch their memory addresses.
I thought this might have been the root of the issue and it seems I was right.
My client's code had been allocating/initializing my View Controller's UIImageViews in
-viewDidAppear instead of in -viewDidLoad. Thus, every time I launched and dismissed a modal view controller my UIImageViews I was animating would get reinitialized.
Check for yourself if your map object's memory address is changing before and after you launch your modals, and if it is be sure to move your initialization logic to a more proper section of your code.
Hope this helps you!

I was using UIView animateWithDuration: and I solved it by not using the completion block. This is code from a subclassed UIView. In the view controller's viewWillAppear: I set self.shouldAnimate to YES, and in the view controller's viewWillDisappear: I set self.shouldAnimate to NO.
-(void)continueRotate {
if (self.shouldAnimate) {
[self rotateRadarView:self.radarInner];
}
}
-(void)rotateRadarView:(UIView *)view {
[UIView animateWithDuration:0.6 delay:0 options:UIViewAnimationOptionCurveLinear animations:^{
[UIView setAnimationDelegate:self];
[UIView setAnimationDidStopSelector:#selector(continueRotate)];
[view setTransform:CGAffineTransformRotate(view.transform, M_PI_2)];
}completion:nil];
}
