UINavigationController - 导航控制器

UINavigationControllerHideShowBarDuration ： push pop 时间

初始化

//    UINavigationController *nav = [[UINavigationController alloc]initWithNavigationBarClass:[UINavigationController class] toolbarClass:[UIToolbar class]];
  
    
    ViewController *view = [ViewController new];
    UINavigationController *nav = [[UINavigationController alloc]initWithRootViewController:view];
    [UIApplication sharedApplication].keyWindow.rootViewController = guidePageViewController;

转场

    oneViewController *one = [oneViewController new];
    [self.navigationController pushViewController:one animated:YES];// push 下一个
    
    [self.navigationController popViewControllerAnimated:YES];// pop 上一个 VC
    
    ViewController *view = [ViewController new];
    [self.navigationController popToViewController:view animated:YES];// pop 到某个VC
    
    [self.navigationController popToRootViewControllerAnimated:YES];// pop root

    oneViewController *one = [oneViewController new];
    twoViewController *two = [twoViewController new];
    [self.navigationController setViewControllers:@[self,one,two]];// 一次设置多个子VCs
    [self.navigationController setViewControllers:@[self,one,two] animated:YES];// 同上

获取

    self.navigationController.topViewController;// 顶部
    self.navigationController.visibleViewController;// 可见
    NSArray *arr = self.navigationController.viewControllers;// 所有

    self.navigationController.navigationBar;
    self.navigationController.toolbar;

    ```

## 系统左侧滑

// 左侧向右滑动，代替pop，（也可以自己设置方法，但是注意需要手势代理)
self.navigationController.interactivePopGestureRecognizer.enabled = YES;
self.navigationController.interactivePopGestureRecognizer.delegate = self;
[self.navigationController.interactivePopGestureRecognizer addTarget:self action:@selector(newPop)];

-(void)newPop{
NSLog(@"pop");
}


## 隐藏

// push 隐藏 Nav
oneViewController *one = [oneViewController new];

[self.navigationController setNavigationBarHidden:YES];或者：
self.navigationController.navigationBarHidden = YES;

[self.navigationController pushViewController:one animated:YES];

// 下面toolBar 类似
oneViewController *one = [oneViewController new];

[self.navigationController setToolbarHidden:YES];
self.navigationController.toolbarHidden = YES;

[self.navigationController pushViewController:one animated:YES];


## 代理

(void)navigationController:(UINavigationController *)navigationController didShowViewController:(UIViewController *)viewController animated:(BOOL)animated;
