I have a window with a UIView and a transition to another UIView. But when I do the transition, the window to transition to is displayed in portrait, and after the transition is finished, it goes to landscape.. But I want the UIView to be in landscape BEFORE the transition because otherwise the screen looks f*cked up because the background image is made for landscape mode. Here is my code:
UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:1.0];
[UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:window cache:YES];
[[oldView view] removeFromSuperview];
[window addSubview:newView.view];
[UIView commitAnimations];
The orientation property of the newWindow is set to landscape in the interface builder, and also in the superview...
What am I doing wrong??
Thanks in advance!
First of all, you should not use multiple window, it will never give you the result you are expecting...
You can easily do the same thing with one window and 2 UIViews.
Solved... I had to put the commitAnimations part above the addSubview:newView
Hope this helps everyone with the same issue....

I want a roll-up animation for the uiview. So i am animating a mainscrollview and a rollupboard. So in the viewDidLoad i set the frame of these two views as:
dashRollUpStand=[[UIImageView alloc]initWithFrame:CGRectMake(0,346,320,0)];
mainScrollView=[[UIScrollView alloc]initWithFrame:CGRectMake(10,346,300,0)];
And i also have many subviews for this mainScrollView.
Now i am loading this view with a roll-up animation using the following code:
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1];
[UIView setAnimationCurve:UIAnimationCurveLinear];
[dashRollUpStand setFrame:CGRectMake(0,0,320,346)];
[mainScrollView setFrame:CGRectMake(10,9,300,337)];
[UIView commitAnimations];
This rollup animation is working fine in iphone. But on iphone retina display this animation is not at all smooth. So how can i make it smooth in iphone retina display.
Is there a reason why you are adding your views in viewDidLoad and having them offscreen?
It seems to me that you should do it like this. In the code below containerView is the view that contains your views, toView is the view you are flipping to and fromView is the view you are flipping from.
[UIView transitionWithView:containerView
duration:1.0
options:UIViewAnimationOptionTransitionFlipFromRight
animations:^{
[fromView removeFromSuperview];
[containerView addSubview:toView];
}
completion:NULL];
I also chose to use the block-based animation/transition API which is the recommended way since iOS 4.
EDIT:
Since you are not actually transitioning the view, even though your original code did. You could just use a normal animation block instead
[UIView animateWithDuration:1.0
animations:^{
[dashRollUpStand setFrame:CGRectMake(0,0,320,346)];
[mainScrollView setFrame:CGRectMake(10,9,300,337)];
}
completion:NULL];
The problem is not the kind of animations you are using, but more probably what you have iside your views. First of all try to make sure that subviews inside your animated view are opaque, opaque is a property of UIView, but it is overridden if the alpha of the view is less that 1. The rendering system requires more clicles to blend clear views, if you can go for opaque.
Is it possible to turn a view slowly like turning a page? When i swipe from right to left, the current view will turn and the next view will be shown. And from left to right, the previous view will come slowly as we move the finger.
How can I do it? Any ideas??
You should add and remove subviews from your view by detecting the touch movements, using the animation transtion styles:
UIViewAnimationTransitionCurlUp //for removing views (vice-versa)
UIViewAnimationTransitionCurlDown // for adding views (vice-versa)
like:
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.3];
[UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:self.view cache:NO];
[self.view addSubview:nextView];
[UIView commitAnimations];
You should customize above according to ur needs.
Hope this helps.

So I have an app where you play a game, and at the end it asks you your name for recording of the high score. I would like to use a modal view to accomplish this, but I am experiencing some hiccups along the way. So far, all I have is the modal view sliding up all the way to the top of the screen, but there isn't anything there yet, it's just blank:
UINavigationController *navController = [UINavigationController new];
[self presentModalViewController:navController animated:YES];
I have seen on several other iPhone apps, the ability to make the modal view come only half way up the screen (or less) and then have a textfield where you can receive input, such as for my high score list. How would I go about restricing the size of the modal view? And perhaps adding a textfield onto it? Any help would be appreciated! Thanks
What makes you think presentModalViewController was used?
You can do this quite easily with an UIViewController and animation.
Using Animation, a sample would look like something like this:
//Move Screen UP:
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDelegate:self];
[UIView setAnimationDuration:0.5];
[UIView setAnimationBeginsFromCurrentState:YES];
self.view.frame = CGRectMake(self.view.frame.origin.x, (self.view.frame.origin.y - kTextView_Keyboard_Offset), self.view.frame.size.width, self.view.frame.size.height);
[UIView commitAnimations];
Where the "kTextView_Keyboard_Offset is defined in my Contants. You would specify/replace with your Offset value equal the number of pixels in the direction that you would like to move.
Define a full-screen view with a transparent background - then put the obscuring content wherever you like.
Then you just bring it up as you would any other modal view.
I'm trying to animate a UIView so that it can grow larger when tapping a button and shrinks down to its original size by tapping the button again.
I do this by adjusting frame to its new size and origin and running the code below.
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1.5];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
self.theView.frame = frame;
[UIView commitAnimations];
When animating to a bigger size the animation is how it should be. But when animating to its original size (smaller) the view is re-sized instantly and then animated to its designated location.
What I need is that the resizing to the smaller frame is animated as well.
I've tried adjusting the autoresizingMask as well, but that didn't change anything.
Hope someone can help.
thanks.
Michiel, Raj,
I made a youtube tutorial showing how to make views expand and shrink like in the facebook iPhone app.
Hope it can be of some help: How to make expanding/shrinking views on iPhone SDK

Try this
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1.5];
[UIView setAnimationRepeatAutoreverses:YES];
self.theView.frame = frame;
[UIView commitAnimations];
In response to comment;
If you want to control animation reverse, have a flag like BOOL isbig and set it in app launch to NO, then toggle it in every button tap, then check it if it is YES or NO, and according to the result call a method. If NO, call your code, if not call the code again but this time set the frame to the original size.
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1.5];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
self.theView.frame = originalFrame;
[UIView commitAnimations];
I could solve the problem by suggestion found in other thread, it has its own limitations though. I have posted the code in the same thread where the solution was suggested:
UIView scaling during animation
I worked around this problem when releasing my app by just removing the animation.
It kept bugging me in the back of my mind, so just this week I thought that maybe by using the center property and the size instead of the origin it would make a difference.
So I decided to test this out. Guess what. The problem doesn't occur when using sdk 4.x
Thanks all for trying to help me out.
In photo app of iphone you can see smooth scrolling to the other picture with finger flicking. Is it possible to allow individual view to be 'flipped' (or rotated) to show its back side ? Found that UIScrollView is used for smooth scrolling and found the code for flipping UI. Outside of UISCrollView I got the flip to work using the code below. But once inside UIScrollView this doesn't work - it executes but UI never switches.
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationTransition: UIViewAnimationTransitionFlipFromLeft forView:myView cache:YES];
[UIView setAnimationDuration:1.0];
[myView exchangeSubviewAtIndex:0 withSubviewAtIndex:1];
[UIView commitAnimations];
Perhaps this is not suppose to work this way. What is the recommended way or technique to have flippable individual views inside the UIScrollView ?
Never mind. It does work. Once inside UIScrollView there were several UIViews and I needed to make sure I grab the pointer to current UIView. The above code works in this case as well. I was doing a flip on a view which was hidden :)
