iOS开发 控制器间项目跳转跳转

一、导航控制器

(2)返回指定页面

A->B->C->D->A

有A一直push到D，在D页面pop返回B页面:

for(UIViewController * tempvc in self.navigationController.childViewControllers){

        if([tempvc isKindOfClass:[B(UIViewController) class]]){

            [self.navigationController popToViewController:tempvc animated:true];

        }

  }

(2) 返回更控制器：

[self.navigationController popToRootViewControllerAnimated:true];

二、模态试图跳转

(1)返回指定页面 A->B->C->D->A

在D页面想返回B页面

 UIViewController * tempvc = self.presentingViewController;

    while (tempvc.presentingViewController) {

        tempvc = tempvc.presentingViewController;

        if([tempvc isKindOfClass:[UIViewController class]]){

            break;

        }

    }

    [tempvc dismissViewControllerAnimated:true completion:nil];

(2) 返回更控制器：

UIViewController * tempvc = self.presentingViewController;

    while (tempvc.presentingViewController) {

        tempvc = tempvc.presentingViewController;

    }

    [tempvc dismissViewControllerAnimated:true completion:nil];
