self.navigationController跳转

• 如果一级一级的返回直接调用就行
• [self.navigationController popViewControllerAnimated:Yes];
  
  

很多情况下可能想要马上回到主页面，而不是一级一级的返回，或者直接返回pop出N个界面.

---

• 返回根页面用 ：
• self.navigationController popToRootViewController］
  

• 返回指定的某级Nvc用下面 

  • 第N级 
  • [self.navigationController popToViewController:[self.navigationController.viewControllers objectAtIndex:N] animated:YES];
    

或指定控制器

//遍历控制器for (UIViewController *controller in self.navigationController.viewControllers) 

{

if ([controller isKindOfClass:[你要跳转到的Controller class]]) {  

[self.navigationController popToViewController:controller animated:YES]; 

}}

• 一次性pop到上上一级
• int index = (int)[[self.navigationController viewControllers]indexOfObject:self];  
• [self.navigationController popToViewController:[self.navigationController.viewControllers objectAtIndex:(index -2)] animated:YES];
