Question

this is the screen shot of storyboard

我正在使用myList = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] def organizeList(li): finalList = [] sortList = li sortList.sort() for x in range(len(li)): pop = sortList.pop() if len(finalList) % 2 == 0: finalList.append(pop) else: finalList.insert(0, pop) return finalList print(myList) # Returns [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] print(organizeList(myList)) # Returns [1, 3, 5, 7, 9, 10, 8, 6, 4, 2] print(myList) # Returns []并尝试使用此代码推送其他视图控制器：

SWRevealViewController

它运行良好，但我无法将该视图控制器弹出到以前的视图控制器.. 我使用了所有基本的popViewcontrollers代码仍然无法正常工作。我只是想不出来该怎么做。请任何机构有诀窍请做什么回复请.. 提前谢谢....

Answer 1

请使用pushFrontViewController：代替setFrontViewController：

代码是这样的：

[revealController pushFrontViewController:frontController animated:YES];

它可能对您有所帮助。

之后，您可以从视图控制器弹出。

Answer 2

您可以使用以下代码

将应用导航到其他viewControllers

UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
// here you need to create storyboard ID of perticular view where you need to navigate your app 
UIViewController *vc = [mainStoryboard instantiateViewControllerWithIdentifier:@"viewContIdentifire"];

// if use presentViewController this will not enables you to go back to previous view
[self presentViewController:vc animated:NO completion:nil];
                    **// OR**
// using pushViewController lets you to go back to the previous view
[self.navigationController pushViewController:vc animated:YES];

注意：使用其中一种方法presentViewController或pushViewController进行导航。

根据popToRootViewControllerAnimated堆栈使用popToRootViewControllerAnimated，popToRootViewControllerAnimated和UI方法处理回弹。

// this takes your app to the root view controller
[self.navigationController popToRootViewControllerAnimated:YES];

// this will takes you to the previous view loaded in stack
[self.navigationController popToRootViewControllerAnimated:YES];

// this takes to any view controller, use accordingly 
[self.navigationController popToViewController:yourViewControllerName animated:YES];

SWRevealViewController无法将视图控制器弹出到上一个
