cabasicanimation

I am popping a view controller from navigation controller.When i am popping controller i want to give it animation like Pushing a view controller.For that purpose i am using below code CATransition* transition = [CATransition animation]; transition.duration = 0.3f; transition.type = kCATransitionPush; transition.subtype = kCATransitionFromRight; [self.navigationController.view.layer addAnimation:transition forKey:kCATransition]; [self.appDelegate setUpForLVC]; [self.navigationController popViewControllerAnimated:NO]; When animation starts i get black effect here.Please tell me what is the

I have a custom CALayer that draws radial gradients. It works great except during animation. It seems that each iteration of CABasicAnimation creates a new copy of the CALayer subclass with empty, default values for the properties: In the screenshot above, you see that CABasicAnimation has created a new copy of the layer and is updating gradientOrigin but none of the other properties have come along for the ride. This has the result of not rendering anything during the animation. Here's a GIF: Here's what is should look like: Here's the animation code: let animation = CABasicAnimation(keyPath:

I'm implementing a game, in which i have some CABasicAnimations. For example, like this : CABasicAnimation * borddroit = [CABasicAnimation animationWithKeyPath:@"transform.translation.x"]; borddroit.fromValue = [NSNumber numberWithFloat:0.0f]; borddroit.toValue = [NSNumber numberWithFloat:749.0f]; borddroit.duration = t; borddroit.repeatCount = 1; [ImageSuivante2.layer addAnimation:borddroit forKey:@"borddroit"]; I put it in pause with this function : -(void)pauseLayer:(CALayer*)layer { CFTimeInterval pausedTime = [layer convertTime:CACurrentMediaTime() fromLayer:nil]; layer.speed = 0.0; layer
