iOS Push & pop

1. 还有其他控制器的push 及 pop 操作

1.1 push 一个控制器

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

 

1.2 pop 操作

pop到根控制器:

[self.navigationController popToRootViewControllerAnimated:YES];

 

pop栈顶控制器:

[self.navigationController popViewControllerAnimated:YES];

 

pop到指定的控制器,方法一

[self.navigationController popToViewController:[self.navigationController.viewControllers objectAtIndex:3] animated:YES];

 

pop到指定控制器,方法二

遍历当前导航控制器下的所有的子控制器,只要找到合适的控制器就跳过去.

for (UIViewController *temp in self.navigationController.viewControllers) {

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

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

}

}
