- (void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated
This function load a view from right side. How can I Load a view from left side?
Here it is
CATransition *animation = [CATransition animation];
[[self navigationController] pushViewController:elementController animated:NO];
[animation setDuration:0.45];
[animation setType:kCATransitionPush];
[animation setSubtype:kCATransitionFromLeft];
[animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionDefault]];
[[elementController.view layer] addAnimation:animation forKey:#"SwitchToView1"];
For this you have to #import <QuartzCore/QuartzCore.h>
don't think there is a readymade way to do that. You will have to animate the view yourself using animateWithDuration:delay:options:animations:completion: or animateWithDuration:animations:completion: (or any other animation methods) and change frames of your view accordingly so that it animates from the right side.
Hope this helps :)
if you already been pushed to a viewController you can use this:
[self.navigationController popViewControllerAnimated:YES]

I am having four ViewControllers , where the ViewControllers are loaded using the UINavigationController. I am able to switch to every ViewController one by one.
The thing is, since I am using the NavigationController all the ViewControllers are loaded either from the Left or from the Right. But I want to load the ViewController from the Bottom. I know I can use presentModalViewController to present the ViewController from the Bottom. But it is not equivalent to the Navigation Controller because , from the 4th ViewController, If I press one button , I need to come to the 1st ViewController.
How can I present a ViewController from the bottom in the NavigationController ?
Try this:
CATransition *animation = [CATransition animation];
[animation setDuration:2];
[animation setType:kCATransitionPush];
[animation setSubtype:kCATransitionFromTop];
[animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];
SecondView *sObj=[[SecondView alloc] initWithNibName:#"SecondView" bundle:nil];
[self.navigationController pushViewController:sObj animated:YES];
[[sObj.view layer] addAnimation:animation forKey:#"SwitchToView1"];
Use this may this will help you
[UIView beginAnimations:#"Hide Me" context:nil];
[UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
[UIView setAnimationDuration:kAnimationDur];
subScroll.frame = CGRectMake(0,ksubScrollHideY,ksubScrollW,ksubScrollH);
clickPic.frame = CGRectMake(kButtonX,kButtonHiddenY,kButtonW,kButtonH);
[UIView setAnimationDelegate:self];
[UIView commitAnimations];
Happy Coding :)
after you create the viewController, instead of:
[self.navigationController pushViewController:blablabla animated:YES];
do:
[self presentModalViewController:blablabla animated:YES];
and it will come from the bottom.
to go back, just say:
[self dismissViewControllerAnimated:YES];
i have a web based application with only one view controller. i have some shortcut buttons in my app which will load some urls. what i need is a push animation as like
pushViewController each time when i click the shortCut buttons.
i have only one UIView .
so, i have found the solution myself,
push like animation for any view
CATransition *animation = [CATransition animation];
[animation setDuration:0.5];
[animation setType:kCATransitionPush];
[animation setSubtype:kCATransitionFromRight];
[animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];
[[self.view layer] addAnimation:animation forKey:#"SwitchToView1"];
thanks for your feedbacks,
I have my main view, and when a user taps a 'Show' button I want two things to happen:
Fade in a black UIView with alpha 0.5 covering the entire parent
view. I'll refer to this as darkenBackground
Slide the view of a second view controller
(self.secondViewController.view) on top of darkenBackground
When a user is finished, they tap 'Done' and the following happens:
darkenBackground fades out and is removed from the superview.
self.secondViewController.view slides out of the screen in the
bottom direction and is removed from the superview.
All animations working simultaneously.
So far, I've been able to achieve the first part (sort-of), transition-in. This works fine. But when the user taps 'Done' the transition-out does not work as required. The problems I'm faced with are:
darkenBackground and self.secondViewController.view fade out and are removed, but
self.secondViewController.view wasn't supposed to fade out! I tried animating only the second view but it simply disappears without animation.
When a user taps 'Show' for a second time
(transition-in), the view from the previous transition
appears before the animation takes place. It doesn't look like it
was removed from the superview previously.
Here is my code:
When a user taps 'Show':
- (IBAction)showSecondView {
darkenBackground = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 320, 460)];
[darkenBackground setBackgroundColor:[UIColor blackColor]];
[darkenBackground setAlpha:0.5];
self.secondViewController.view.frame = CGRectMake(0, 0, 320, 460);
self.secondViewController.view.backgroundColor = [UIColor clearColor];
[CATransaction begin];
CATransition *animation = [CATransition animation];
[animation setDuration:0.5];
[animation setType:kCATransitionFade];
CATransition *animation2 = [CATransition animation];
[animation2 setDuration:0.5];
[animation2 setType:kCATransitionMoveIn];
[animation2 setSubtype:kCATransitionFromTop];
[animation2 setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];
[self.view addSubview:darkenBackground];
[self.view addSubview:self.secondViewController.view];
[[self.view layer] addAnimation:animation forKey:#"darkenBkgFadeIn"];
[[self.secondViewController.view layer] addAnimation:animation2 forKey:#"ShowSecondView"];
[CATransaction commit];
}
When a user taps 'Done' (A function defined in the secondViewController.m class where it refers to the main view controller variables through delegate):
- (IBAction)hideSecondView {
[CATransaction begin];
CATransition *animation = [CATransition animation];
[animation setDuration:0.5];
[animation setType:kCATransitionFade];
CATransition *animation2 = [CATransition animation];
[animation2 setDuration:0.5];
[animation2 setType:kCATransitionPush];
[animation2 setSubtype:kCATransitionFromBottom];
[animation2 setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];
[self.myParentController.darkenBackground removeFromSuperview];
[self.myParentController.secondViewController.view removeFromSuperview];
[[self.myParentController.view layer] addAnimation:animation forKey:#"darkenBkgFadeOut"];
[[self.myParentController.secondViewController.view layer] addAnimation:animation2 forKey:#"RemoveSecondView"];
[CATransaction commit];
}
Ultimately I want to show the view in the same way that the TWTweetComposeViewController modal view appears, where the background darkens and the controller appears. I could just use a modal view controller, but the issue I have with that is that when presenting the view controller it only 'appears' and does not slide from the bottom (since I require a semi-transparent background, I cannot use the default context for the modal view).
Cannot figure this one out, would appreciate some guidance.
I assume that self.myParentController.view used in -hideSecondView is the same view as self.view in -showSecondView. If this is the case, then you're applying a transition to the whole view here:
[[self.myParentController.view layer] addAnimation:animation forKey:#"darkenBkgFadeOut"];
You added self.secondViewController.view as a subview of self.view in -showSecondView, so when you later perform a transition on self.myParentController.view, it's going to apply the transition to all its subviews (i.e., self.secondViewController.view) as well.
Instead of applying the transition to self.myParentController.view in -hideSecondView, apply it directly to darkenBackground:
[[self.myParentController.darkenBackground layer] addAnimation:animation forKey:#"darkenBkgFadeOut"];
If I recall correctly, you can apply CATransitions when layers are added/removed to/from a view. If not, then you'll have to wrap darkenBackground in a separate container view and perform the transitions on that so it doesn't include self.secondViewController.view when you do the fade out.
XYZAppDelegate *appdelegate=[[UIApplication sharedApplication] delegate];
CSelectorViewController *cPrice=[[CSelectorViewController alloc] initWithNibName:#"CSelectorViewController" bundle:nil];
[cPrice.view setFrame:CGRectMake(0, 20, 320, 480)];
[appdelegate.window addSubview:cPrice.view];
[self applyAnimation];
[cPrice release];
i am adding a view like this,not using navigationcontroller,since i have to switch two views top-bottom also.but when i am giving the [cPrice release]; the app crashes. but when i am not giving it in code... the static analyser is showing a warning..what is the right way to do this?
-(void)applyAnimation
{
CATransition *animation = [CATransition animation];
[animation setDuration:0.5];
[animation setType:kCATransitionPush];
[animation setSubtype:kCATransitionFromRight];
[animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];
XYZAppDelegate *appdelegate=[[UIApplication sharedApplication] delegate];
[[appdelegate.window layer] addAnimation:animation forKey:#"slideLeft"];
}
You're adding the view of cPrice to the window as a subview (which will implicitly retain the view), but you do nothing to preserve cPrice itself. You should make it a retained property or some such.
I have a working transition using UIViewAnimationTransitionCurlUp however, I would like the animation to stop halfway through, much like the Maps application...Any thoughts on how to achieve this?
In iOS 3.2 and later, you can give your UIViewController a UIModalTransitionStyle of UIModalTransitionStylePartialCurl. From the UIViewController reference, we see
typedef enum {
UIModalTransitionStyleCoverVertical = 0,
UIModalTransitionStyleFlipHorizontal,
UIModalTransitionStyleCrossDissolve,
UIModalTransitionStylePartialCurl,
} UIModalTransitionStyle;
So an example use case would be:
UIViewController *viewController;
// …create or retrieve your view controller…
// Note: The modalPresentationStyle must be UIModalPresentationFullScreen,
// and the presenter must also be a full-screen view
viewController.modalPresentationStyle = UIModalPresentationFullScreen;
viewController.modalTransitionStyle = UIModalTransitionStylePartialCurl;
I found a solution to add an UIView to UIViewController using Animation block.
m_Container is an UIView who contain my view animation (self).
self is an UIView.
CAUTION : You need to have import QuartzCore
To present view with page curl animation you can use :
-(void)PresentView
{
[UIView animateWithDuration:1.0
animations:^{
CATransition *animation = [CATransition animation];
[animation setDelegate:self];
[animation setDuration:0.7];
[animation setTimingFunction:UIViewAnimationCurveEaseInOut];
animation.type = #"pageCurl";
animation.fillMode = kCAFillModeForwards;
animation.endProgress = 0.65;
[animation setRemovedOnCompletion:NO];
[m_container.layer addAnimation:animation forKey:#"pageCurlAnimation"];
[m_container addSubview:self];
;}
];
}
And when you want hide this view you can use :
-(void)HideHelpView
{
[UIView animateWithDuration:1.0
animations:^{
CATransition *animation = [CATransition animation];
[animation setDelegate:self];
[animation setDuration:0.7];
[animation setTimingFunction:UIViewAnimationCurveEaseInOut];
animation.type = #"pageUnCurl";
animation.fillMode = kCAFillModeForwards;
animation.startProgress = 0.35;
[animation setRemovedOnCompletion:NO];
[m_container.layer addAnimation:animation forKey:#"pageUnCurlAnimation"];
[self removeFromSuperview];
;}
];
}
The Maps partial curl is a private API. You can find details of how to use it in Erica Sadun's book The iPhone Developer's Cookbook, but you will get rejected from the App Store for using it.
Not sure if this will work, but the parameter to +setAnimationRepeatCount: can be a fraction.
