使用popViewController从一个导航堆栈切换到另一个导航堆栈

Question

我创建了一个模块，其中我有5个类，我需要执行像

这样的任务

vc1-＆GT; vc2-＆GT; VC3

现在从vc3我习惯从基类的引用推送vc4。 基类是一个将vc1控制器添加为子视图的类。

现在我需要从vc4弹出到vc3。

Answer 1

NSInteger index = 0;
for (UIViewController *view in self.navigationController.viewControllers) {
  if([view.nibName isEqualToString:@"YourViewController"])//put any `XIB name` where u want to navigate 
  break;
index = index + 1;
}
 //[[self navigationController] pushViewController:[[self.navigationController viewControllers] objectAtIndex:index] animated:YES];

[[self navigationController] popToViewController:[[self.navigationController viewControllers] objectAtIndex:index] animated:YES];    

Answer 2

NSArray *array = [self.navigationController viewControllers];

[self.navigationController popToViewController:[array objectAtIndex:2] animated:YES];

获取要弹出的视图控制器的索引。
