iphone - 在每个段索引添加视图控制器内的段控制

Question

每个 selectedSegmentIndex 添加不同的视图控制器。

在第一次segmentindex 点击，呈现新的视图控制器和第二段索引，呈现另一个视图控制器。

和段控制只显示底部。（不在导航栏中添加）。

段控制，因为它是可见的每个视图控制器（如标签栏控制器）。

我的问题是当新控制器弹出段控制器禁用时。需要帮助才能完成这项工作。

在 .h 文件中尝试此代码添加

进口

@interface SegmentManagingViewController : UIViewController <UINavigationControllerDelegate> {
    UISegmentedControl    * segmentedControl;
    UIViewController      * activeViewController;
    NSArray               * segmentedViewControllers;
   IBOutlet UILabel *theLabel;
    IBOutlet UIImageView *image;
   }
//-(void)setTextColorsForSegmentedControl:(UISegmentedControl*)segmented;
@property (nonatomic, retain, readonly) IBOutlet UISegmentedControl * segmentedControl;
@property (nonatomic, retain, readonly) UIViewController * activeViewController;
@property (nonatomic, retain, readonly) NSArray * segmentedViewControllers;

@end

在 .m 文件中添加

 #import "SegmentManagingViewController.h"
     #import "CategoryViewController.h"
     #import "AtoZViewController.h"

    @interface SegmentManagingViewController ()

    @property (nonatomic, retain, readwrite) IBOutlet UISegmentedControl * segmentedControl;
