Monotouch: How to change default animation of view change with NavigationController.PushViewController - animation

Question

I'm using NavigationController for navigation in my app. When the PushViewController starts(someUIViewController,true), it change view with default animation(move from right to left for child controller). How can i change this animation ? Now i'm using this:
this.NavigationController.PushViewController(someUIViewController,true);
UIView.BeginAnimations(null);
UIView.SetAnimationDuration(0.4);
UIView.SetAnimationTransition(UIViewAnimationTransition.FlipFromRight, NavigationController.View,true);
UIView.CommitAnimations();
But I'm limited to four UIViewAnimationTransition types.I found what I needed(the appearance of the view from the bottom to up):
this.NavigationController.PushViewController(someUIViewController,true);
var theAnimation = CABasicAnimation.FromKeyPath("transform.translation.y");
theAnimation.Duration = 0.3f;
theAnimation.From = NSNumber.FromFloat(this.View.Frame.Height);
theAnimation.To = NSNumber.FromFloat(0f);
NavigationController.View.Layer.AddAnimation(theAnimation, "animate");
NavigationController.View.Layer.AnimationForKey("animate");
But when CABasicAnimation starts, default animation (move from left to right to parent controller) starts too.The result is a wrong combination.How can I run only one(translation on y) or make custom animation?

Answer 1

I believe you need to change the call to PushViewController to not animate to avoid the default animation kicking in.
this.NavigationController.PushViewController(someUIViewController,true);
Should be
this.NavigationController.PushViewController(someUIViewController,false);

Was same problem. There is no normal solution for this. PushViewController is limited by the standard animation(type of UIViewAnimationTransition). If you want to change them, try this:
NavigationController.PushViewController(screen, false);
var theAnimation = CABasicAnimation.FromKeyPath("transform.translation.x");
theAnimation.Duration = 0.6f;
theAnimation.From = NSNumber.FromFloat(-NavigationController.View.Frame.Width);
theAnimation.To = NSNumber.FromFloat(0f);
NavigationController.View.Layer.AddAnimation(theAnimation, "animate");
NavigationController.View.Layer.AnimationForKey("animate");
But it is not perfect, try and u see why. Also u can use PresentViewController. It have some other standart animations in UIModalTransitionStyle:
this.NavigationController.PresentViewController(new UINavigationController(screen){
ModalTransitionStyle= UIModalTransitionStyle.CoverVertical,
}, true,null);

//Allows a UINavigationController to push using a custom animation transition
public static void PushControllerWithTransition(this UINavigationController
target, UIViewController controllerToPush,
UIViewAnimationOptions transition)
{
UIView.Transition(target.View, 0.75d, transition, delegate() {
target.PushViewController(controllerToPush, false);
}, null);
}
//Allows a UINavigationController to pop a using a custom animation
public static void PopControllerWithTransition(this UINavigationController
target, UIViewAnimationOptions transition)
{
UIView.Transition(target.View, 0.75d, transition, delegate() {
target.PopViewControllerAnimated(false);
}, null);
}
// With these extensions in scope, moving between controllers with a flip animation is now as trivial as this:
//Pushing someController to the top of the stack
NavigationController.PushControllerWithTransition(someController,
UIViewAnimationOptions.TransitionFlipFromLeft);
//Popping the current controller off the top of the stack
NavigationController.PopControllerWithTransition(
UIViewAnimationOptions.TransitionFlipFromRight);
