Disable animation of navigation bar in iphone

[bimaldas]

I am working on a Navigation-Based Application. I have few View Controllers which I push in to Navigation Controller on different occasions. The following is the code I use to push new View Controller.

AnotherViewController *anotherViewController = [[AnotherViewController alloc] initWithNibName:@"AnotherView" bundle:nil];
[self.navigationController pushViewController:anotherViewController animated:YES];
[anotherViewController release];


One thing i noticed is that, when new view controller is pushed the navigation bar also animated (slided). I have a back button, title text and right button in navigation bar. So it look wiered when navigation bar is animated.

Is there any way around to keep the navigation bar fixed and the view is only animated when new view controller is pushed?

Are the contents the same or are they different? If you don't mind the quite bluntness of no animation then try

[self.navigationController pushViewController:nextController animated:NO];

or make try messing around with custom animations using CATransitions there are quite a few nice provided options the one below does a fade left to right.

-(void)performTransition 
{

	CATransition *transition = [CATransition animation];
	transition.duration = 0.75;
	transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
	transition.type = kCATransitionFade;
	[self.navigationController.view.layer addAnimation:transition forKey:nil];
	
}

adding animation to viewController.view.layer will affect the navigationBar and the views in the view controller. I wanted to disable the animation of navigation bar only. I fixed it by setting animation to navigationbar.view.layer

thanks

I'm trying to disable the navigation bar animation too. Please could you show how you did it by setting animation to navigationbar.view.layer?

Thanks

It is not disabling animation what i did. Here is the code what i wrote. try with different values for duration. Let me know if it helps.


CATransition *navTransition = [CATransition animation];
navTransition.duration = 1;
navTransition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseO ut];
navTransition.type = kCATransitionPush;
navTransition.subtype = kCATransitionPush;
[self.navigationController.navigationBar.layer addAnimation:navTransition forKey:nil];

Thanks for the response!

The same as you I want to keep the navigation bar fixed and have only the view animated when a view controller is pushed or pop for the stack.

Does this code you provided help me achieve this?
Where should I put it in my app?

[bimaldas]

Add the code in viewWillAppear.

I put it in navigationController willShowViewController which should be the same as in viewWillAppear and the navigation bar still shows the animation when pushing or popping the views. Any ideas?

did you try adding the code in viewWillAppear?
