Any way to emulate something like this? Isn't there an API for doing something like a "Half page curl" or something?
controller.modalTransitionStyle = UIModalTransitionStylePartialCurl;
[self presentModalViewController:controller animated:YES];
UIModalTransitionStyle
Transition styles available when presenting view controllers modally. The below are the four different transition styles. The "UIModalTransitionStylePartialCurl" is the one you're after.
typedef enum {
UIModalTransitionStyleCoverVertical,
UIModalTransitionStyleFlipHorizontal,
UIModalTransitionStyleCrossDissolve,
UIModalTransitionStylePartialCurl,
} UIModalTransitionStyle;
Apple documentations: http://developer.apple.com/library/ios/#documentation/UIKit/Reference/UIViewController_Class/Reference/Reference.html
Hope this helps!
Try the following. In this case Settings is a sublcass UIViewController to be presented behind the page curl. self is also a UIViewController that is being displayed an it's view will stay on top.
-(void)presentSettings{
Settings *eset = [[Settings alloc] init];
//eset.modalPresentationStyle = UIModalPresentationFullScreen;
eset.modalTransitionStyle = UIModalTransitionStylePartialCurl;
[self presentModalViewController:eset animated:YES];
}
Notice that the Curl is only available in iOS 3.2 and later.
I think this may be what you're looking for:
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1];
[UIView setAnimationBeginsFromCurrentState:YES];
[UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:self.view cache:YES];
[UIView commitAnimations];

i am working with page curling effect .on click of a button i was able to transit the page(i.e between the UIViews).the following code depicts the same
UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:1.5];
if ([sender tag] == 1) {
[UIView setAnimationTransition:UIViewAnimationTransitionCurlDown forView:placeholder cache:YES];
}
else {
[UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:placeholder cache:YES];
}
if (view1OnTop) {
[view1 removeFromSuperview];
[placeholder addSubview:view2];
}
else {
[view2 removeFromSuperview];
[placeholder addSubview:view1];
}
[UIView commitAnimations];
view1OnTop = !view1OnTop;
with this i was able to curl between UIViews ,but my question is , will i be able to apply this kind of transition between two or more classes???
thanks in advance
Not everything is animatable. Only parts of UIKit are. So if you mean to ask if any subclass of NSObject can be animated then no they can't. If you mean to ask if whether subclasses of UIView can be animated then the answer would be yes. They can be different subclasses too. While this is possible, it doesn't mean it will give us the right results. They might end up looking pretty weird. You might not want to do that.
Layers are animatable too.
However it all depends on what you mean by classes.
Animating to a new view controller
Say you want to alter the way you shift between view controllers, you can use transitionWithView:duration:.. class method of UIView. An example,
SecondViewController * viewController = [[[SecondViewController alloc] initWithNibName:nil bundle:nil] autorelease];
[UIView transitionWithView:self.view.window
duration:1.0f
options:UIViewAnimationOptionTransitionCurlUp
animations:^{
[self.navigationController pushViewController:viewController animated:NO];
}
completion:NULL];
This will use the curl up transition when pushing the new view controller.
For iOS versions older than 4.0
Since they don't support block based animation APIs, you will have to do this,
[UIView beginAnimations:#"Curl up" context:NULL];
[UIView setAnimationDuration:1.0f];
[UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:self.view.window cache:YES];
[self.navigationController pushViewController:viewController animated:NO];
[UIView commitAnimations];
I want to show a custom animation when pushing a view controller: I would like to achieve something like an "expand" animation, that means the new view expands from a given rectangle, lets say [100,100 220,380] during the animation to full screen.
Any suggestions where to start, respectively any documents, tutorials, links? :)
Alright. I could make the expand animation with the following code:
if ([coming.view superview] == nil)
[self.view addSubview:coming.view];
coming.view.frame = CGRectMake(160,160,0,0);
[UIView beginAnimations:#"frame" context:nil];
[UIView setAnimationDuration:4];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[coming viewWillAppear:YES];
[going viewWillAppear:YES];
coming.view.frame = CGRectMake(0, 0, 320, 480);
[going viewDidDisappear:YES];
[coming viewDidAppear:YES];
[UIView commitAnimations];
My View is properly displayed, but unfortunately the navigation bar is not updated. Is there a way to do that manually?
In the sample code, a function is called all 0.03 seconds that updates the transformation of the view.
Unfortunately, when pushing a UIViewController, I am not able to resize the frame of the view ... am I ?
I use the following function (added to UINavigationController) to customize the push animation:
- (void) pushController: (UIViewController*) controller
withTransition: (UIViewAnimationTransition) transition
{
[UIView beginAnimations:nil context:NULL];
[self pushViewController:controller animated:NO];
[UIView setAnimationDuration:.5];
[UIView setAnimationBeginsFromCurrentState:YES];
[UIView setAnimationTransition:transition forView:self.view cache:YES];
[UIView commitAnimations];
}
I guess you could adapt this code to do whatever animation you want.
The code which you are looking for:
[UIView beginAnimations:#"View Flip" context:nil];
[UIView setAnimationDuration:0.80];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationTransition:
UIViewAnimationTransitionFlipFromRight
forView:self.navigationController.view cache:NO];
[self.navigationController pushViewController:menu animated:YES];
[UIView commitAnimations];
What you could do is push the next view controller but don't animate it, like so:
[self.navigationController pushViewController:nextController animated:NO];
...and then, in the view controller that is getting pushed in, you could do a custom animation of it's view using CoreAnimation. This might be best done in the viewDidAppear:(BOOL)animated method.
Check out the Core Animation Guide on how to actually do the animation. Look particularly at the implicit animation.
EDIT: updated link
#zoul: That worked great! I just changed "self" to "self.navigationController" and "self.view" to "self.navigationController.view" Don't know if that was necessary, but it worked. And #crafterm, as for popping back, just make your own leftBarButtonItem by adding this code in viewDidLoad or ViewWillAppear:
//add your own left bar button
UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithTitle:#"Back" style:UIBarButtonItemStylePlain target:self action:#selector(backButtonTapped)];
self.navigationItem.leftBarButtonItem = backButton;
[backButton release];
Then I just tweaked the push function and made this popWithTransition function that I called in my -backButtonTapped method.
- (void) popWithTransition: (UIViewAnimationTransition) transition
{
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:.75];
[UIView setAnimationBeginsFromCurrentState:YES];
[UIView setAnimationTransition:transition forView:self.navigationController.view cache:YES];
[UIView commitAnimations];
[self.navigationController popViewControllerAnimated:NO];
}
Note that the popViewController call got shifted down to the end, after the animation. Don't know if that's kosher, but again, it worked.
What you want is the downloads for chapter 2 of iphone developers cookbook. Look at the affineRotate sample specifically, although any of the core animatin samples will help you.
Have a look at ADTransitionController, a drop in replacement for UINavigationController with custom transition animations (its API matches the API of UINavigationController) that we created at Applidium.
You can use different pre-defined animations for push and pop actions such as Swipe, Fade, Cube, Carrousel and so on. In your case, the animation you are requesting is the one called Zoom.
I had a look around and didn't find what I was exactly looking for.
Is there a way to get a flip animation when pushing a view controller?
I read that you can change the animation by using a modal view controller but AFAIK the animation for a modal view is from bottom to top and that's not what i am looking for. Is there a way to get a flip animation somehow?
something like this should work
[UIView beginAnimations:#"animation" context:nil];
[self.navigationController pushViewController: yourviewcontroller animated:NO];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:self.navigationController.view cache:NO];
[UIView commitAnimations];
don't forget to set animated to NO when calling pushViewController
This also works.. for iOS 4.0 and greater
[UIView transitionWithView:self.navigationController.view duration:0.8 options:UIViewAnimationOptionTransitionFlipFromLeft
animations:^(void) {
BOOL oldState = [UIView areAnimationsEnabled];
[UIView setAnimationsEnabled:NO];
[self.navigationController pushViewController:viewController animated:YES];
[UIView setAnimationsEnabled:oldState];
}
completion:nil];
- (void)viewWillDisappear:(BOOL)animated {
[UIView beginAnimations:#"animation2" context:nil];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationDuration: 0.7];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:self.navigationController.view cache:NO];
[UIView commitAnimations]; }
in the new viewcontroller will make it flip back the same way (instead of sliding left) when the back button in the toolbar is pushed -- make sure animation is enabled here, e.g., if you make a custom button to pop the stack, use:
- (void) backToPrevious: (id) sender
{
//[self.navigationController popViewControllerAnimated:YES];
[self dismissModalViewControllerAnimated:YES];
}
For modally presented view controllers, you can change the animation with the modalTransitionStyle property. AFAIK, there is no way to change a navigation controller's push animation (except rebuilding UINavigationController from scratch).

I'm having some trouble getting a view to flip. I have the following code in my View Controller:
- (void)loadFlipsideViewController {
ProblemViewFlipController *viewController = [[ProblemViewFlipController alloc] initWithNibName:#"ProblemViewFlip" bundle:nil];
self.problemViewFlipController = viewController;
[viewController release];
}
- (void) flipView {
if (problemViewFlipController == nil) {
[self loadFlipsideViewController];
}
UIView *mainView = self.view;
UIView *flipView = problemViewFlipController.view;
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:1];
[UIView setAnimationTransition:([mainView superview] ? UIViewAnimationTransitionFlipFromLeft : UIViewAnimationTransitionFlipFromRight) forView:self.view cache:YES];
if ([flipView superview])
{
[flipView removeFromSuperview];
[self.view addSubview:mainView];
}
else
{
[mainView removeFromSuperview];
[self.view addSubview:flipView];
}
[UIView commitAnimations];
}
The problem is, is that when I call flipView, the view is replaced with a blank view (i.e. nothing in the view I'm flipping to is displayed).
Is there something obvious I'm missing here? (I suspect there is!)
Not positive, but I think you need to use a 'controller' to flip the views. Looks like you're using one of the flipped views as the controller. Just add a root controller to flip your views.
Code like this should work from the root controller:
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:1];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.view cache:YES]; // self.view is the root controller's view
[mainViewController viewWillAppear:YES];
[flipViewController viewWillDisappear:YES];
[flipViewController.view removeFromSuperview];
[self.view addSubview:mainViewController.view];
[flipViewController viewDidDisappear:YES];
[mainViewController viewDidAppear:YES];
[UIView commitAnimations];
Based on the variable names, it looks like this is adapted from the default "Utility" application template you get from XCode. If the template project works, and yours doesn't, then you've obviously changed something you shouldn't have :-)
Chances are, one of the outlets in your controller that should be pointing at a view, isn't. Double-check your Nibs, and check the values of the outlets in the debugger. If all else fails, start over again from the template, and see at what point it stops working.
