I have figured out the solution for this problem and here is the solution as below:-

#import <UIKit/UIKit.h>

@interface ViewController : UIViewController
{
    IBOutlet UIButton *backbtn;
    IBOutlet UIButton *nxtBtn;
    IBOutlet UILabel *label;
}
-(IBAction)nxt:(id)sender;
-(IBAction)ba:(id)sender;

@end

#import "ViewController.h"

@interface ViewController ()
@end

int count=0;

@implementation ViewController

- (void)viewDidLoad
{
    label.text=[[NSUserDefaults standardUserDefaults] objectForKey:@"NavigtionNumber"];
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
}

- (void)viewDidUnload
{
    [super viewDidUnload];
    // Release any retained subviews of the main view.
}
-(IBAction)nxt:(id)sender
{
    count++;
    label.text=[NSString stringWithFormat:@" navigation time %d",count];

    [[NSUserDefaults standardUserDefaults] setObject:label.text forKey:@"NavigtionNumber"];
    [[NSUserDefaults standardUserDefaults] synchronize];

    ViewController *vc=[[ViewController alloc] init];

    [self.navigationController pushViewController:vc animated:YES];

}

-(IBAction)ba:(id)sender
{
    count--;
    label.text=[NSString stringWithFormat:@" navigation time %d",count];

    [[NSUserDefaults standardUserDefaults] setObject:label.text forKey:@"NavigtionNumber"];
    [[NSUserDefaults standardUserDefaults] synchronize];

    [self.navigationController popViewControllerAnimated:YES];
}


- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);
}

@end

Hope this will help others in future.

Thanks.
