iOS - Storyboards


Advertisements


Storyboards are introduced in iOS 5. When we use storyboards, our deployment target should be 5.0 or higher. Storyboards help us create all the screens of an application and interconnect the screens under one interface MainStoryboard.storyboard. It also helps in reducing the coding of pushing/presenting view controllers.

Steps Involved

Step 1. Create a single view application and make sure that you select storyboard checkbox while creating the application.

Step 2. Select MainStoryboard.storyboard where you can find single view controller. Add one more view controllers and update the view controllers as shown below.

Step 5. Update ViewController.h as follows −

#import <UIKit/UIKit.h>

@interface ViewController : UIViewController

-(IBAction)done:(UIStoryboardSegue *)seque;

@end

Step 6. Update ViewController.m as follows −

#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad
{
    [super viewDidLoad];	
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}
-(IBAction)done:(UIStoryboardSegue *)seque{
    [self.navigationController popViewControllerAnimated:YES];
}

@end

Step 7. Select the MainStoryboard.storyboard and right-click on the Exit button in the right side view controller, select done and connect with the back button as shown below.
