我自己写的一个自定义UINavigationController，可以很方便地定制UINavigationController的navigationBar背景样式，比较炫的push和pop效果，不多说，上代码。

重写-(void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated方法，以下是动画的关键代码

UIView * toView = [viewControllerview];

CABasicAnimation *Animation = [CABasicAnimationanimationWithKeyPath:@"transform"];

CATransform3D rotationAndPerspectiveTransform =CATransform3DIdentity;

rotationAndPerspectiveTransform.m34 =1.0 / -1000;

rotationAndPerspectiveTransform =CATransform3DMakeTranslation(self.view.frame.size.width,0,0);

[Animation setFromValue:[NSValuevalueWithCATransform3D:CATransform3DMakeTranslation(self.view.bounds.size.width,0,0)]];

[Animation setToValue:[NSValuevalueWithCATransform3D:CATransform3DMakeTranslation(0,0,0)]];

[AnimationsetDuration:0.3];

Animation.delegate =self;

//no表示动画会保持最后的状态，yes会返回到最初的状态

Animation.removedOnCompletion =NO;

Animation.fillMode =kCAFillModeBoth;

[toView.layeraddAnimation:AnimationforKey:@"fromRight"];

CABasicAnimation *Animation1 = [CABasicAnimationanimationWithKeyPath:@"transform"];

CATransform3D rotationAndPerspectiveTransform1 =CATransform3DIdentity;

rotationAndPerspectiveTransform1.m34 =1.0 / -1000;

rotationAndPerspectiveTransform1 =CATransform3DMakeScale(1.0,1.0,1.0);

[Animation1 setToValue:[NSValuevalueWithCATransform3D:CATransform3DMakeScale(0.95,0.95,0.95)]];

[Animation1setDuration:0.3];

Animation1.delegate =self;

Animation1.removedOnCompletion =NO;

Animation1.fillMode =kCAFillModeBoth;

[animationLayeraddAnimation:Animation1forKey:@"scale"];
