I am Giving a uianimation with Infinite repeats in viewDidAppear: by code given below
[UIView beginAnimations:#"theAnimation" context:NULL];
[UIView setAnimationDuration:2];
[UIView setAnimationRepeatCount:FLT_MAX];
[UIView setAnimationRepeatAutoreverses:YES];
[startButton setAlpha:.5];
[UIView setAnimationDelegate:self];
[UIView setAnimationCurve:UIViewAnimationCurveLinear];
[UIView commitAnimations];
[super viewDidAppear:YES];
but when I am navigating to some page with pushViewController and returning back to same view controller the viewDidAppear is calling but the animation is not working . and works fine when using presentViewController.Can please any one help me with it.
thanks
Try to call [super viewDidAppear:YES]; before animation code.

Really weird issue, i've got a view (view 2) that i'm popping to bring up my main view (view 1) which has an animated background. Once i pop from view 2, view 1 loses those animations... the weird thing is that moving the iOS status bar in the slightest will restart them!
Any ideas?
This is the code that i'm using to pop the view. If I pop the view without animations, it works fine.
-(IBAction)popOnSwipe {
[UIView beginAnimations:#"" context:nil];
[UIView setAnimationDuration:0.75];
[UIView setAnimationCurve:UIViewAnimationTransitionCurlDown];
[UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:self.navigationController.view cache:NO];
[navController popViewControllerAnimated:NO];
[UIView commitAnimations];
One more thing; the animation starts back up on the simulator, but not on the iTouch i'm testing it on. Any insight would be greatly appreciated,
thanks!
Add your animations for view1 in DidStopSelector method like,
-(IBAction)popOnSwipe
{
[UIView beginAnimations:#"" context:nil];
[UIView setAnimationDuration:0.75];
[UIView setAnimationCurve:UIViewAnimationTransitionCurlDown];
[UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:self.navigationController.view cache:NO];
[UIView setAnimationDidStopSelector:#selector(view1_animation)];//add this line
[navController popViewControllerAnimated:NO];
[UIView commitAnimations];
}
-(void)view1_animation
{
//do animations for view1
}
The device I was using was faulty, the method works fine on my other devices. Thanks for the help.
I am using such code to present a new view, I don't it's good or not. Currently the default animation is show the view from bottom up, but i want it to animate from right to left(fly in), is it possible to change the default animation type and how? Thanks.
[self presentModalViewController:navController animated:animated];
You can disable the slide-up animation like this:
[self presentModalViewController:navController animated:NO];
Then you can provide your own animation code:
navController.view.frame = CGRectMake(320, 0, navController.view.frame.size.width, navController.view.frame.size.height);
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.5];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
navController.view.frame = CGRectMake(0, 0, navController.view.frame.size.width, navController.view.frame.size.height);
[UIView commitAnimations];
This example gives you the "Fly-in" from right with a smooth speed-curve.
Another way is using the built in slide-in from right with navigationcontroller:
[self.navigationController pushViewController:navController animated:YES];
In this one, your top-viewcontroller needs to be a UINavigationController and it's rootcontroller needs to be your viewcontroller. Then you can push other viewcontrollers.
I have done this and its working for me try ths:
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.6];
[UIView setAnimationDelegate:self];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.View2.superview cache:YES];
[self.View2 removeFromSuperview];
[self performSelector:#selector(replaceViews2) withObject:nil afterDelay:0.6];
[UIView commitAnimations];
I am new to iPhone developer,
I want to implement different Animations on button click, i have 5 Button in my home page
on each click of button, i want to navigate to a new page with different Animation so i want to know what are the different animation available in iPhone.
so far i have found only 2 animation,
(1)
[UIView beginAnimations:#"yourAnim" context:nil];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:yourView cache:cacheFlag];
...
[UIView commitAnimations];
(2)
[UIView beginAnimations:#"yourAnim" context:nil];
[UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:yourView cache:cacheFlag];
...
[UIView commitAnimations];
Thanks In Advance !
This link provides the UIView Animation. Go through it.
http://www.raywenderlich.com/5478/uiview-animation-tutorial-practical-recipes
These are 5 different Animation Transition:
UIViewAnimationTransitionNone,
UIViewAnimationTransitionFlipFromLeft,
UIViewAnimationTransitionFlipFromRight,
UIViewAnimationTransitionCurlUp,
UIViewAnimationTransitionCurlDown,
Look at CATransition class too
https://developer.apple.com/library/mac/#documentation/graphicsimaging/reference/CATransition_class/Introduction/Introduction.html
I think bellow method from you can test different type of Transition 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];
}
You Can Get Idea From this May Be.....
i have used viewcontroller with multiple view.
when i go back to previous, there is no animation
i have tried by below lines of code ,
-(IBAction)goback
{
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:1];
[UIView setAnimationTransition: UIViewAnimationTransitionCurlDown forView:self.view cache:YES];
[self.view removeFromSuperview];
[UIView commitAnimations];
}
You can't animate a method call. You can only animate properties of the view such as frame, size, alpha etc. removeFromSuperview isn't a property, it is a method that simply finds the superview and removes the originating view from the array of subviews.
You need to run the animation and then send removeFromSuperview when the animation completes.
use below code
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:1];
[UIView setAnimationTransition:UIViewAnimationTransitionCurlDown forView:self.view.superview cache:YES];
[self.view removeFromSuperview];
[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.
