如何使用UINavigationController从一个视图中推送多个视图 [英] How do I push many Views from one View using UINavigationController

问题描述

我使用 UINavigationController 编写了许多转换应用程序。

I code many transition App using UINavigationController.

这是我的转换图片

This is my transition image

1. Main - >Second - >Third - >Fourth


2. Second - >A - >B


3. Second - >C



4. Third - >D

1. "Main"-->"Second"-->"Third"-->"Fourth"
2. "Second"-->"A"-->"B"
3. "Second"-->"C"

4. "Third"-->"D"

• Main是RootViewController。


• 在No2和No3， if（[booisEqual：foo]）{transitA} else if（boo......）{transitC} 。

• "Main" is RootViewController.
• At No2 and No3, if (["boo" isEqual:"foo"]){transit "A"} else if ("boo"...){transit "C"}.

我可以将Main改为Forth ，No.1过渡。

喜欢这个

I could make "Main" to "Forth", No.1 transition.
like this

ThirdViewController *thirdView = [[ThirdViewController alloc] init];
[self.navigationController pushViewController:thirdView animated:YES];

但我无法将秒变为A和B。

我想把UIRootViewController设置为Second。

但是Second需要转换A和C。

But I can't make "Second" to "A"and "B".
I thought to set UIRootViewController to "Second".
But "Second" needs to transit "A" and "C".

atSecond就像这样......

at "Second" like this...

SecondViewController.m

AViewController *aView = [[AViewController alloc] init];
[self.navigationController pushViewController:aView animated:YES];

我如何编码？

谢谢您！对不起英语不好。

请帮帮我！

Thank you! And sorry in poor English.
Please help me!

推荐答案

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