改变UIViewController的push方式

UIViewController的push默认的是从右往左压入栈，但是有时我们需要其他的方式例如，是从左往右压入栈。还有其他各种方式，如下
方法一：是通过给导航栏下要压入栈的控制器对应的view的layer添加动画
- (IBAction)toPersonalCenterViewControllerAction:(id)sender {
UIStoryboard *board = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
PersonalCenterViewController *vc = [board instantiateViewControllerWithIdentifier:@"PersonalCenterViewController"];

CATransition *transition = [CATransition animation];
transition.duration = .5f;
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionLinear];
transition.type = kCATransitionPush;push方法
transition.subtype = kCATransitionFromLeft;从左到右
transition.delegate = self;
[self.controller.navigationController.view.layer addAnimation:transition forKey:nil];

[self.controller.navigationController pushViewController:vc animated:YES];

}
对应的动画效果，还有对应的动画方向如下
transition.type

/* Common transition types. */

CA_EXTERN NSString * const kCATransitionFade
__OSX_AVAILABLE_STARTING (__MAC_10_5, __IPHONE_2_0);
CA_EXTERN NSString * const kCATransitionMoveIn
__OSX_AVAILABLE_STARTING (__MAC_10_5, __IPHONE_2_0);
CA_EXTERN NSString * const kCATransitionPush
__OSX_AVAILABLE_STARTING (__MAC_10_5, __IPHONE_2_0);
CA_EXTERN NSString * const kCATransitionReveal
__OSX_AVAILABLE_STARTING (__MAC_10_5, __IPHONE_2_0);

transition.subtype

/* Common transition subtypes. */

CA_EXTERN NSString * const kCATransitionFromRight
__OSX_AVAILABLE_STARTING (__MAC_10_5, __IPHONE_2_0);
CA_EXTERN NSString * const kCATransitionFromLeft
__OSX_AVAILABLE_STARTING (__MAC_10_5, __IPHONE_2_0);
CA_EXTERN NSString * const kCATransitionFromTop
__OSX_AVAILABLE_STARTING (__MAC_10_5, __IPHONE_2_0);
CA_EXTERN NSString * const kCATransitionFromBottom
__OSX_AVAILABLE_STARTING (__MAC_10_5, __IPHONE_2_0);

方法二：通过自定义navigationController
#import <UIKit/UIKit.h>
@interface CustomViewController : UINavigationController
@end

@implementation CustomViewController

-(UIViewController * )popViewControllerAnimated:(BOOL)animated
{
if (animated) {
[UIViewbeginAnimations:@"1"context:nil];
[UIViewsetAnimationCurve:UIViewAnimationCurveLinear];
[UIViewsetAnimationDuration:1];
[UIViewsetAnimationTransition:UIViewAnimationTransitionFlipFromRightforView:self.viewcache:NO];
[UIViewcommitAnimations];

}
return [superpopViewControllerAnimated:animated];
}
-(void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated
{
if (animated) {
[UIViewbeginAnimations:@"2"context:nil];
[UIViewsetAnimationCurve:UIViewAnimationCurveLinear];
[UIViewsetAnimationDuration:2];
[UIViewsetAnimationTransition:UIViewAnimationTransitionCurlDownforView:self.viewcache:NO];
[UIViewcommitAnimations];
}
[super pushViewController:viewController animated:animated];
}
@end
