Xcode - 分段控件更改为默认

我有这个xcode应用程序，有2个视图控制器在主要有2个按钮（第一个是一个按钮，弹出一个alertview和第二个是一个按钮之间移动视图）。在第二个视图中，我有一个分段的4段控制器，当您选择其中一个时，返回到第一个视图，然后返回到分段控制器视图，分段控制器返回到第一个段......我该如何解决这个？Xcode - 分段控件更改为默认

这里是.m文件

看不懂。发布您的细分控制的一些代码。更多地解释你的需求。 –

您想要在按下分段时立即回到第一个视图并立即转到第二个视图。但该细分受众群应保留最后一次点击的位置。对？ –

不，我想段是设置的排序，但当我回到第一个视图，然后它变回默认...我添加了一些代码 – user1289671

代码如果我明白你的问题，这将是你的答案。

@interface firstViewController : UIViewController{ 

    firstViewController *secondView; 
} 

//add this where you push to the secondView 

if(!secondView) 
    secondView = [[secondViewController alloc] init]; 
//This will init the second view only one time. So the position of your segments will retain its state. 
    [[self navigationController]pushViewController:photocontent animated:YES]

nahh我猜你不明白..我有2个视图在同一个视图控制器上，我有第二个视图的段控制，每次我从第一个视图移动到第二个视图段控件选择第一个段（段0）。 – user1289671
