UINavigationController-SeraphExtension

  • An extension for UINavigationController, you can custom push/pop animation.
  • 轻耦合的UINavigationController扩展，可以自定义push/pop动画。

How to use

  • Step 1. add the extension to your project. Just drag the "UINavigationController+SeraphExtension" folder into your xcode
  • Step 2. add import in your sourcefile #import "UINavigationController+SE.h"
  • Step 3. use - (void)se_pushViewController:(UIViewController *)viewController animated:(BOOL)animated type:(SENavigationControllerAnimationType)type; to push a viewController instead of - (void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated

如何使用

  • 步骤 1. 把这个扩展放入项目中。直接拖拽"UINavigationController+SeraphExtension"文件夹到源代码
  • 步骤 2. 添加头文件#import "UINavigationController+SE.h"
  • 步骤 3. 使用方法- (void)se_pushViewController:(UIViewController *)viewController animated:(BOOL)animated type:(SENavigationControllerAnimationType)type;来代替系统方法- (void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated

What else ? / 还有啥？

  • you can set animation duration / 你可以设置动画时间
self.navigationController.se_animationDuration = [NSNumber numberWithDouble:0.25]; // need a NSNumber wrapper here
  • you can set whether to hide bottom bar / 你可以设置是否隐藏tabbar
self.navigationController.se_hidesBottomBarWhenPushed = [NSNumber numberWithBool:NO]; // need a NSNumber wrapper here
  • you can use your own animation / 你可以使用自定义的动画
self.transition = [[TestTransition alloc] init];
self.navigationController.se_customTransition = self.transition;

// TestTransition need to inherit from class SENavigationTransition
#import <UIKit/UIKit.h>
#import "SENavigationTransition.h"
@interface TestTransition : SENavigationTransition
@end

// implementation these two methods here
@implementation TestTransition
- (NSTimeInterval)transitionDuration:(id<UIViewControllerContextTransitioning>)transitionContext {
    return 0.25;
}
- (void)animateTransition:(id<UIViewControllerContextTransitioning>)transitionContext {
    // Get the two view controllers
    UIViewController *fromVC = [transitionContext viewControllerForKey:UITransitionContextFromViewControllerKey];
    UIViewController *toVC = [transitionContext viewControllerForKey:UITransitionContextToViewControllerKey];
    
    // Get the container view
    UIView *containerView = [transitionContext containerView];
    [containerView addSubview:fromVC.view];
    [containerView addSubview:toVC.view];
    toVC.view.alpha = 0.0;
    toVC.view.transform = CGAffineTransformMakeScale(2.0, 2.0);
    
    // Perform the animation
    [UIView animateWithDuration:[self transitionDuration:transitionContext]
                          delay:0
                        options:0
                     animations:^{
                         toVC.view.alpha = 1.f;
                         toVC.view.transform = CGAffineTransformIdentity;
                     }
                     completion:^(BOOL finished) {
                         [fromVC.view removeFromSuperview];
                         [transitionContext completeTransition:YES];
                     }];
}
