应用程序试图以模态方式呈现活动控制器 [英] Application tried to present modally an active controller

问题描述

我已经搜索并找到了有关此错误的各种 q/a，但无法找到针对我的问题的任何具体帮助(至少我的最低经验让我能够理解).

I have searched for and found various q/a on this error, but have not been able to find any specific help for my issue (at least that my minimal experience allows me to understand).

我正在从应用程序的主菜单加载一个 UIView，该菜单又具有几个按钮选项(称为子菜单).其中之一毫无问题地返回到主菜单([self dismissModalViewControllerAnimated:YES];).另一个按钮加载 UITableView (单独的视图控制器)，加载正常.但是，我希望此 UITableView 中的按钮返回子菜单.当我使用上面提到的代码时，它会一直回到主菜单.我似乎无法找到一种方法来创建返回子菜单 UIView(子菜单)的操作.

I am loading a UIView from the app's main menu, which in turn has several button options (call it submenu). One of these goes back to the main menu without issue ([self dismissModalViewControllerAnimated:YES]; ). Another button loads a UITableView (separate view controller), which loads fine. However, I want a button within this UITableView to go back to the submenu. When I use the above mentioned code, it goes all of the way back to the main menu. I can't seem to find a way to create an action that goes back to the submenu UIView (submenu).

当我尝试做一个标准 ['uitableviewcontrollername' presentModalViewController:submenuView animated:YES]; 我收到错误应用程序试图以模态方式呈现活动控制器(我如果我将 uitableviewcontrollername 替换为 self，则会出现相同的错误.

When I try to do a standard ['uitableviewcontrollername' presentModalViewController:submenuView animated:YES]; I get the error Application tried to present modally an active controller (I get the same error if I replace uitableviewcontrollername with self.

这个错误是有道理的，因为我知道它已经处于活动状态，但我需要帮助的是，执行上述操作的正确方法是什么?感谢您的宝贵时间.

The error makes sense in that I understand that it is already active, but what I need help with is, what exactly is the proper way to do what I've described above? Thanks for your time.

针对我的特定需求，以下是从tableview返回的技巧:

For my specific needs, the following did the trick for getting back from thetableview:

[self.mapLegendViewControllerdismissModalViewControllerAnimated:YES];

Gregory 的观点已被注意到，我建议阅读他制作的链接，因为有趣的是 iPhone/iPad 各自如何处理这些操作.

Gregory's point is noted though, and I recommend reading the link he made as it is interesting as to how iPhone/iPad each handle these actions.
