In this tutorial we will see how view webpage in our application. If we want to load web pages from within our application, we must embed a web browser in our application through the use of the UIWebView. Using Web view, we can send a request to load web content. The following Try It Out shows how to use the Web view to load a Web page.

TRY IT OUT  Loading a Web Page Using the Web View

#import 
@interface UsingViews2ViewController : UIViewController {
IBOutlet UIWebView *webView;
}
@property (nonatomic, retain) UIWebView *webView;
@end

5 In Interface Builder, connect the webView outlet to the Web view.


6. In the UsingViews2ViewController.m file, add the following statements that appear in bold:

#import “UsingViews2ViewController.h”
@implementation UsingViews2ViewController
@synthesize webView;
- (void)viewDidLoad {
NSURL *url = [NSURL URLWithString:@”http://www.apple.com”];
NSURLRequest *req = [NSURLRequest requestWithURL:url];
[webView loadRequest:req];
[super viewDidLoad];
}
- (void)dealloc {
[webView release];
[super dealloc];
}

7. Press Command-R to test the application on the iPhone 4 Simulator. You should see the application
loading the page from Apple.com.

How It Works

To load the Web view with a URL, you first instantiate an NSURL object with a URL via the URLWithString method:

NSURL *url = [NSURL URLWithString:@”http://www.apple.com”];

You then create an NSURLRequest object by passing the NSURL object to its requestWithURL: method:

NSURLRequest *req = [NSURLRequest requestWithURL:url];

Finally, you load the Web view with the NSURLRequest object via the loadRequest: method:

[webView loadRequest:req];
