控制器中添加控制器的常见方法

控制器中添加控制器的常见方法：

1 添加子控制器：addChildViewController:

2 modal出控制器： presentViewController:<#(nonnull UIViewController *)#> animated:<#(BOOL)#> completion:<#^(void)completion#>

3 设置为rootViewController

4 UINavgationController push出来控制器：pushViewController:<#(nonnull UIViewController *)#> animated:<#(BOOL)#>

5 UINavgationController 跳转到最新的一个控制器：（不论是push出来的仍是pop出来的)

- (void)setViewControllers:(NSArray<UIViewController *> *)viewControllers animated:(BOOL)animated NS_AVAILABLE_IOS(3_0); // If animated is YES, then simulate a push or pop depending on whether the new top view controller was previously in the stack.

 用法实例：

    NSMutableArray *vcs = self.navigationController.viewControllers.mutableCopy;

    [vcs removeLastObject];

    SS_SaleStatisticsVC *vc = [[UIStoryboard storyboardWithName:@"SS_SaleStatisticsVC" bundle:nil] instantiateInitialViewController];

    [vcs addObject:vc];

    [self.navigationController setViewControllers:vcs animated:YES];
