Tab Bar Controller

Tab Bar Controller'da Navigation Controller gibi birçok ekran arası geçişi sağlar.
Tek farkı bir UIView üzerine birden fazla ekran basabilmemiz.Navigation Controller'da birçok UIView kullandık.
Öncelikle yeni bir proje oluşturuyoruz.

XCode'da  oluşturduğumuz projenin görünümü yukarıdaki gibidir.Her görüntülemek için farklı birer Objective-C sınıfı oluşturuyoruz.

Şimdi kodlama kısmına geçelim.
VIEWCONTROLLER.H

#import <UIKit/UIKit.h>

@interface ViewController : UIViewController

@property (nonatomic, retain) IBOutlet UITabBarController *tabBarController;

@end

VIEWCONTROLLER.M
//
//  ViewController.m
//  tabBarAplication

#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController

@synthesize tabBarController=_tabBarController;


- (void)viewDidLoad
{
    [super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
 
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

@end


ViewController sınıfları arasında bir fark yok.Diğer sınıflarıda aynı şekilde kodluyoruz.Uzatmamak için sadece ViewController.h ve ViewController.m sınıflarını yazdım.

{

    // Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.

    // Use this method to pause ongoing tasks, disable timers, and throttle down OpenGL ES frame rates. Games should use this method to pause the game.

}

- (void)applicationDidEnterBackground:(UIApplication *)application

{

    // Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later. 

    // If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.

}

- (void)applicationWillEnterForeground:(UIApplication *)application

{

    // Called as part of the transition from the background to the inactive state; here you can undo many of the changes made on entering the background.

}

- (void)applicationDidBecomeActive:(UIApplication *)application

{

    // Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.

}

- (void)applicationWillTerminate:(UIApplication *)application

{

    // Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.

}

Oluşturduğum ViewControllerların isimlerine de belirledikten sonra NSArray’a attım ve return ettim.

Return ettiğim bu viewler tabBarda görüntülenecek.

Uygulamanın ekran görüntüsü örneği aşağıdaki gibidir.

Ekran görüntüsünü elde ettik.Kolay Gelsin:)
