Segment control inside add view controller every segment index

Question

Every selectedSegmentIndex add different view controller.

On first segmentindex click, present new viewcontroller and second segment index, present another viewcontroller.

and segment control only show bottom.(not add in navigation bar).

segmentcontrol as it is visible every view controller(like tab bar controller).

my problem is that when new controller pop up segment controller disable. Need help in getting this done.

Share some code that you have tried... – Vishal Dec 14 '12 at 10:05 — Vishal, Dec 14 '12 at 10:05

Try this code in .h file add

import

@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

in .m file add

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

    @interface SegmentManagingViewController ()

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

    @property (nonatomic, retain, readwrite) NSArray                     * segmentedViewControllers;
    - (void)didChangeSegmentControl:(UISegmentedControl *)control;
    - (NSArray *)segmentedViewControllerContent;

    @end

Thanks! i already try this code but this code support navigation method like 1)didShowViewController and 2)willShowViewController and i use segment control not navigation bar but bottom like toolbar. — Sneha, Dec 14 '12 at 10:39
You can replace `[self.segmentedViewControllers arrayByPerformingSelector:@selector(title)]` with `[self.segmentedViewControllers valueForKeyPath:@"@unionOfObjects.title"]` to avoid the dependancy on external code.
