How to Change Color of Navigation Bar in iPhone

Introduction

In this article we create an empty view application and use a uiviewcontroller class to navigate from one view to another. For changing the color of the navigation bar we use code in the view load method of each view. In this I use two views, FirstViewController and SecondViewController.

Step 1

Open XCode by double-clicking on it.

Step 2

Create a New XCode Project by clicking on it.

Step 3

Now select Empty View Application and click on Next.

Step 4

Now provide your Product Name, Company Identifier and click on Next.

Step 5

Select the location where you want to save your project to and click on Create.

Step 6

Now you will see in the XCode Window two Objective-C Classes that were generated by XCode; they are:

1. Appdelegate.h
2. AppDelegate.m

Now we add two UIViewControllers; for this we use the following procedure.

Step 7

Select the appdelegate.m class and right-click on it, as in:

Choose "New File".

Step 8

Select "Subclass of UIViewController" from the drop down list and give a class name. Here I use "First view controller" for the class name. Then click on the checkbox with the xib use interface. Add a label and button from xib.

Click on Next.

Step 9

Now click on "Create" to import a class into the project, as in:

Repeat the steps to add the second view controller class.

Step 10

After that we code for navigation and to do the linking.

Step 11

To change the color of the navigation bar we use the following code in the appdelegate.m Objective-C file:

#import "AppDelegate.h"

@implementation AppDelegate
@synthesize window = _window;
@synthesize nav,first;

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
first =[[FirstViewController alloc]init];
self.nav=[[UINavigationController alloc]initWithRootViewController:first];
// Override point for customization after application launch.
self.window.rootViewController = self.nav;
nav.navigationBar.tintColor=[UIColor colorWithRed:42/256.0 green:60/256.0 blue:80/256.0 alpha:1.0];
self.window.backgroundColor = [UIColor whiteColor];
[self.window makeKeyAndVisible];
return YES;
}
@end

Step 12

Now select which platform you want to see output for.
