catransition

I am trying to create a category for UINavigationController so I can put together a few custom animations. I came across this question and it got me started. I've come up with the following for a push function: - (void)pushViewControllerMoveInFromBottom:(UIViewController *)viewController { [CATransaction begin]; CATransition *transition; transition = [CATransition animation]; transition.type = kCATransitionMoveIn; transition.subtype = kCATransitionFromBottom; transition.duration = 0.7; [CATransaction setValue:(id)kCFBooleanTrue forKey:kCATransactionDisableActions]; [[[[self.view subviews]

I animated the appearance of my subview with: CATransition *transition = [CATransition animation]; transition.duration = 0.3; transition.type = kCATransitionReveal; [webView.layer addAnimation:transition forKey:nil]; [self.view addSubview:webView]; But now I want to remove my subView. How can I add animation to do this? Like other CATransition? When to add this? Before or after addSubview? Krishnabhadra Well you could do the animation first and on the animationEndListener call removeFromSuperView [UIView animateWithDuration:0.5 delay:1.0 options: UIViewAnimationOptionCurveEaseOut animations:^{

I have a UINavigationController , and push from the root view controller to the next view controller. This second view controller is fairly "heavy", in that it has a great deal of initialization and subviews. My issue is this: the transition animation performs terribly. Basically, the animation suffers from a very low frame rate (I get maybe 3-4 frames in total out of the "push" animation). I've tried a variety of different techniques, including two different methods to manually animate the transition. In all cases, the first 0.4-0.7 seconds of the animation suffers from this poor framerate.

I have a side navigation controller and present it via a UIButton. When I make this NC the root view controller directly by [self presentviewcontroller: NC animated: YES completion: nil] , some reason the menu side of the NC is blocked by a UITransitionView that I cannot get to disappear. I've attached an image of the . is another. I have tried the following: UIWindow *window = [(AppDelegate *)[[UIApplication sharedApplication] delegate] window]; window.backgroundColor = kmain; CATransition* transition = [CATransition animation]; transition.duration = .5; transition.timingFunction =

i have two views,one is aView,another is bView, there is a button on aView,i click the button ,i will jump to bView,please see the code -(IBAction)jump2b:(id)sender{ CATransition *animation = [CATransition animation]; animation.delegate = self; animation.duration = 0.25f; animation.timingFunction = UIViewAnimationCurveEaseInOut; animation.fillMode = kCAFillModeForwards; animation.removedOnCompletion = NO; animation.type = kCATransitionPush; animation.subtype = kCATransitionFromTop; [bView.view.layer addAnimation:animation forKey:@"animation"]; } it can not work well,it can jump,so what can i

I'm working on an app that utilizes the navigation controller. I have a certain view controller that has a left and right button in the navigation bar and each button segues to a different view controller. When I press the right button, I just call self.performSegue(withIdentifier: "ToDestination", sender: nil) and when I pop back I call _ = self.navigationController?.popViewController(animated: true) . My issue is when I press the left button. I can push and pop, but I want the transition to work opposite of the right button. Since I'm pressing the left button, I want the segue to transition

I was using a nice method to dismiss my modal view controller: [self dismissModalViewControllerWithTransition:2]; which makes a slide transition from left to right, like a navigation controller does to pop a view. As this method is a non-public method, apple will not accept it. How can I program this kind of animation in my code (slide from left to right, to dismiss a modal view, and slide from right to left to present a modal view) ? Thanks in advance I have accepted the answer from Safecase, but I would like to publish my final solution here: 1) To present a modal view controller with a from
