推/现模态视图控制器 [英] Push/Present Modal View Controller

问题描述

我在我的视图控制器（我们称之为TVC1）有一个表。我在TVC1中有行使用，所以用户可以输入一些更多的数据除了TVC1上的数据。因此，当有人点击TVC1中的特定行时，它将显示另一个视图控制器（我们称之为TVC2）。然而，当显示TVC2时，TVC1中的所有数据被清除。如何在TVC1中保存数据？

I have a table in my view controller (let's call it TVC1). I have rows in TVC1 that are used so the user can input some more data in addition to the data on TVC1. So, when someone taps a specific row in TVC1, it will show another view controller (let's call it TVC2). However, when TVC2 is shown, all of the data in TVC1 is cleared. How can I save the data in TVC1? Should I do it through the app delegate?

        DescriptionInputViewController *descriptionController = [[DescriptionInputViewController alloc] 
                                                             initWithNibName:@"DescriptionInputView" 
                                                             bundle:nil];

    [self presentModalViewController:navController animated:YES];
    [self.navigationController pushViewController:descriptionController animated:YES];
    [descriptionController release];

推荐答案

p>

In your code, you should be calling:

[self presentModalViewController:descriptionController animated:YES]

descriptionController是您正在显示的视图控制器。

descriptionController is the view controller you are displaying.
