How to Make a Web Browser in Xcode

Making a Web browser in Xcode is relatively easy.

After you install the Xcode developer tools package, you will be able to develop complex apps for iPhone and iPad. Along with the Cocoa framework, Xcode is powerful enough to create an entire operating system, such as iOS or Mac OS X. Developing applications in Xcode is made easy by the Xcode IDE (integrating the Apple LLVM compiler). Due to its versatility, you can use this tool to create a Web browser for your mobile device.

Instructions

1. Open Xcode, go to "File" and click "New Project" to start creating a new project. Select "Window-Based Application" in the "iPhone OS" drop-down menu. Enter a name for your new project and click “Save” to create and open the project in the development section of Xcode.

2. Go to the "Resources" folder and double-click on “MainWindow.xib” to edit it. The Inspector window will open. Locate the “Web View” component and drag it to the main window. It will resize itself automatically to fit your screen.

3. Press and hold the Ctrl key and drag from the Web View from the Inspector window to the “File’s Owner” object in the MainWindow window. Click the "Delegate Outlet" button that pops up, save and close the Inspector window.

4. Go to the "Classes" folder in the left-hand pane and double-click the “WebBrowserTutorialAppDelegate.h” file to edit it.

5. Locate the "UIWindow *window;" line and add this code on the next line:

   IBOutlet UIWebView *webView;

   This will add an UIWebView outlet, named “webView,” to allow us to use it in the main controller.

6. Save and close the file. Open the "WebBrowserTutorialAppDelegate.m" file by double-clicking it. Locate the "- (void)applicationDidFinishLaunching:(UIApplication *)application {" line and add this code on the next line:

   NSURL *url = [NSURL URLWithString:@"www.google.com"];
   NSURLRequest *request = [NSURLRequest requestWithURL:url];
   [webView loadRequest:request];

   This code forces your new browser to navigate to Google. You can enter any URL and even an IP address.

7. Open the “MainWindow.xib” file again. Press and hold the Ctrl key and drag from the “Web Browser Tutorial App Delegate” object to the Web View component in MainWindow. Click the "Delegate Outlet" button that pops up.

8. Compile and build your project. Execute the file on your mobile device and you will have a simple, functional Web browser.
