I want to slide in a ViewController in the screen, and then at some point slide it out and go back to the presenting ViewController.
I use this code from my MainViewController to launch the modal, and then to dismiss it.
Why is the dismiss slide animation not working?
// Present a React Component sliding from the right on top of current ViewController
+ (void)presentSlidingFromRight:(UIViewController*)presented onViewController:(UIViewController*)presenterVC {
CATransition *transition = [[CATransition alloc] init];
transition.duration = 1;
transition.type = kCATransitionPush;
transition.subtype = kCATransitionFromRight;
[presenterVC.view.window.layer addAnimation:transition forKey:kCATransition];
[presenterVC presentViewController:presented animated:NO completion:nil];
}
// Dismiss a React Component sliding to the right
+ (void)dismissSlidingToRight:(UIViewController*)presented onViewController:(UIViewController*)presenterVC {
CATransition *transition = [[CATransition alloc] init];
transition.duration = 3;
transition.type = kCATransitionPush;
transition.subtype = kCATransitionFromLeft;
[presenterVC.view.window.layer addAnimation:transition forKey:kCATransition];
[presenterVC dismissViewControllerAnimated:NO completion:nil];
}
Could you try changing this line:
[presenterVC dismissViewControllerAnimated:NO completion:nil];
for this one:
[presenterVC dismissViewControllerAnimated:YES completion:nil];
Update
Make sure you are calling your static functions on the Main Thread

I am trying to present a view controller on top of a view using the following code
HubViewController* vc = [HubViewController socialHubViewController];
CATransition* transition = [CATransition animation];
transition.duration = 3.0;
transition.type = kCATransitionPush;
transition.subtype = kCATransitionFromBottom;
vc.modalPresentationStyle = UIModalPresentationOverCurrentContext;
[vc.view.layer addAnimation:transition forKey:kCATransition];
[self presentViewController:vc animated:NO completion:^{
NSLog(#"vc: presented");
}];
Does not seem to work. Any help appreciated.
Issues based on navigation check your code.
or use that another way
HubViewController* vc = [HubViewController socialHubViewController];
CATransition* transition = [CATransition animation];
transition.duration = 3.0;
transition.type = kCATransitionPush;
transition.subtype = kCATransitionFromBottom;
vc.modalPresentationStyle = UIModalPresentationOverCurrentContext;
[vc.view.layer addAnimation:transition forKey:kCATransition];
[[UIApplication sharedApplication].keyWindow.rootViewController presentViewController:vc animated:NO completion:^{
NSLog(#"vc: presented");
}];
//UIViewController *topVc = [UIApplication sharedApplication].keyWindow.rootViewController;
Here is my code used to present a navigationViewController :
-(IBAction)showFilterView:(id)sender {
FilterViewController *vc=[self.storyboard instantiateViewControllerWithIdentifier:#"FilterViewController"];
UINavigationController *nvc=[[UINavigationController alloc] initWithRootViewController:vc];
CATransition *transition = [CATransition animation];
transition.duration = 0.35;
transition.timingFunction =
[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
transition.type = kCATransitionMoveIn;
transition.subtype = kCATransitionFromLeft;
UIView *containerView = self.view.window;
[containerView.layer addAnimation:transition forKey:nil];
[self.tabBarController presentViewController:nvc animated:NO completion:nil];
}
And here is my code to dismiss
-(IBAction)back:(id)sender {
CATransition *transition = [CATransition animation];
transition.duration = 0.35;
transition.timingFunction =
[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
transition.type = kCATransitionMoveIn;
transition.subtype = kCATransitionFromRight;
UIView *containerView = self.view.window;
[containerView.layer addAnimation:transition forKey:nil];
[[self.navigationController presentingViewController] dismissViewControllerAnimated:NO completion:nil];
}
Situation 1 --- Working well in landscape mode
Situation 2 --- Working well in portrait mode
Situation 3 --- Presenting in a portrait mode and dismissing in landscape mode not working properly(extra animation before displaying correct view)
Situation 4 ---Presenting in a landscape mode and dismissing in portrait mode not working properly(extra animation before displaying correct view)
The UIWindow layer has weird rotation properties and any animations you perform aren't guaranteed to correctly detect orientation (and vary with different iOS versions). The easiest way to do what you're trying to is with a custom presentation animation. This is a good writeup of how to do it.
This is mouli, I'm implementing a custom segue for pushing (with animation) from firstview to second view, its work fine. but iam not getting back from secondview to firstview with same animation. Here the first screen appears with out animation. please give some suggestion. Thanks in advance. following is my code for push from first to second.
UIViewController *sourceViewController = [UIApplication sharedApplication].delegate.window.rootViewController;
NSLog(#"%#",sourceViewController);
sourceViewController.modalPresentationStyle = UIModalPresentationCurrentContext;
UIViewController *destinationController = (UIViewController*)[self destinationViewController];
NSLog(#"%#",destinationController);
CATransition* transition = [CATransition animation];
transition.duration = 0.6;
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
transition.type = kCATransitionPush; //kCATransitionMoveIn; //, kCATransitionPush, kCATransitionReveal, kCATransitionFade
transition.subtype = kCATransitionFromRight; //kCATransitionFromLeft, kCATransitionFromRight, kCATransitionFromTop, kCATransitionFromBottom
[destinationController.view.layer addAnimation:transition forKey:kCATransition];
[sourceViewController presentViewController:destinationController animated:NO completion:nil];
Do the dismiss in opposite way, since your are doing a custom animation other that the provided one, it doesn't remember the animation of presentation. So while you are dismissing you need to apply the opposite custom animation too.
I would suggest you to create a Category for animations and use them in the whole project easily..
I have a line of viewControllers set in line. The idea is to go through a process of questions etc. If i was to use the already set up way of changing view controller (through button - modal), i would have no problem with memory. I have tried it. However i need to change the views programmatically and not with buttons directly.
When i do this programmatically my memory usage just starts increasing as i go through the views, until eventually i get a Memory Warning and a crash.
To change the viewController i use custom UIStoryBoardSegue and also methods in the viewController files.
Here is how i do it:
Method in View Controller:
-(void)changeViewController
{
CATransition *transition = [CATransition animation];
transition.duration = 0.3;
transition.timingFunction =[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
transition.type = kCATransitionPush;
transition.subtype = kCATransitionFromRight;
[self.view.window.layer addAnimation:transition forKey:nil];
UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:#"Main" bundle:nil];
UIViewController *vc = [mainStoryboard instantiateViewControllerWithIdentifier:#"enterInfoSecondViewController"];
[[[[[UIApplication sharedApplication]delegate]window]rootViewController]presentViewController:vc animated:NO completion:nil];
// [self dismissViewControllerAnimated:YES completion:nil];
//[self presentViewController:vc animated:NO completion:nil];
// [self dismissViewControllerAnimated:NO completion:nil];
}
In custom Segue:
-(void)perform
{
UIViewController *srcViewController = (UIViewController *)self.sourceViewController;
UIViewController*destViewController = (UIViewController *)self.destinationViewController;
CATransition *transition = [CATransition animation];
transition.duration = 0.3;
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
transition.type = kCATransitionPush;
transition.subtype = kCATransitionFromRight;
[srcViewController.view.window.layer addAnimation:transition forKey:nil];
[srcViewController presentViewController:destViewController animated:NO completion:nil];
}
......
Somewhere I do it with segue and somewhere with the top method.
What am i doing wrong? i need help please :) Thank you in advance.
If all you need is to trigger the segue programmatically,
why not use -performSegueWithIdentifier:sender: ?
Is it possible to show pushViewController animation look like presentModalViewController but that has background functionality of pushViewController?
If you want to a fade animation, this approach works.
CATransition* transition = [CATransition animation];
transition.duration = 0.3;
transition.type = kCATransitionFade;
transition.subtype = kCATransitionFromTop;
[self.navigationController.view.layer addAnimation:transition forKey:kCATransition];
[self.navigationController pushViewController:gridController animated:NO];
Try this :
UIViewController *yourViewController = [[UIViewController alloc]init];
[UIView beginAnimations: #"Showinfo"context: nil];
[UIView setAnimationCurve: UIViewAnimationCurveEaseInOut];
[UIView setAnimationDuration:0.75];
[self.navigationController pushViewController: yourViewController animated:NO];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.navigationController.view cache:NO];
[UIView commitAnimations];
For display PushViewConttroler animation as Present below code is working,
For Push
ViewController *VC = [self.storyboard instantiateViewControllerWithIdentifier:#"ViewController"];
CATransition* transition = [CATransition animation];
transition.duration = 0.4f;
transition.type = kCATransitionMoveIn;
transition.subtype = kCATransitionFromTop;
[self.navigationController.view.layer addAnimation:transition
forKey:kCATransition];
[self.navigationController pushViewController:VC animated:NO];
And for POP
CATransition* transition = [CATransition animation];
transition.duration = 0.4f;
transition.type = kCATransitionReveal;
transition.subtype = kCATransitionFromBottom;
[self.navigationController.view.layer addAnimation:transition
forKey:kCATransition];
[self.navigationController popViewControllerAnimated:NO];
There is 1 issue though, that its display light black background when its going up/down,
Working on that, As soon as its done post new code here.
For All Trying in Xamarin (C#) equivalent Code
From Answer by #hardik Thakkar above, Has the issue of Black backgound during animation, rest all good.
For POP
CATransition transition = CATransition.CreateAnimation();
transition.Duration = 0.4;
transition.Type = CAAnimation.TransitionReveal;
transition.Subtype = CAAnimation.TransitionFromTop;
this.NavigationController.View.Layer.AddAnimation(transition, nameof(CATransition));
For Push
CATransition transition = CATransition.CreateAnimation();
transition.Duration = 0.4;
transition.Type = CAAnimation.TransitionReveal;
transition.Subtype = CAAnimation.TransitionFromBottom;
this.NavigationController.View.Layer.AddAnimation(transition, nameof(CATransition));
You should consider doing something like:
ViewController *myVC = [[ViewController alloc] initWithFrame:OFF_SCREEN];
[navigationController pushViewController:myVC animated:NO];
where OFF_SCREEN is some CGRect below the screen, like (0, 481, 320, 480). Then use an animation block to adjust the viewcontroller's view's frame.origin to be (0, 0). You would probably want to do the animate block in viewDidLoad or viewDidAppear.
