Browser View Controller

OVERVIEW

The BrowserViewController is a boilerplate class that handles opening a web page from within your application. This allows you to create a smooth experience within your app for loading web content and then seamlessly getting back into you app.

The icons were generously contributed by Joseph Wain of Glyphish for this project.

QUICK START GUIDE

This boiler plate code support these 3 common scenarios:

UIButton or UITableView

  1. Copy all the files in the "Browser View Controller Boilerplate" folder into your xcode project. (If you never want to use a UITextView or UIWebView than you do not need MyApplication.h or MyApplication.m)

  2. Reference the Browser View Controller header file in the ViewController you want to open the URL from.

    #import "BrowserViewController.h"`
    
  3. Now you can open the Browser View Controller with your own code. Here's a sample method to do it:

    - (void)openURL:(NSURL)url
    {
         BrowserViewController bvc = [[BrowserViewController alloc] initWithUrls:url];
         [self.navigationController pushViewController:bvc animated:YES];
         [bvc release];
    }
    

UITextView

  1. Update the parameters of your UIApplication to specify a subclass. This subclass will allow you to trap requests to open URLs in Safari, and open them from within your app instead. Make sure you have copied MyApplication.h and MyApplication.m, they contain the code that overrides the openURL method.

    int retVal = UIApplicationMain(argc, argv, @"MyApplication", nil);
    
  2. Override the (BOOL)openURL method in your AppDelegate class, and add a corresponding stub in your AppDelegate class header.

    -(BOOL)openURL:(NSURL)url
    {
        BrowserViewController bvc = [[BrowserViewController alloc] initWithUrls:url];
        [self.navigationController pushViewController:bvc animated:YES];
        [bvc release];
    }
    
  3. Update MyApplication.m with the name of your AppDelegate class to reference the method you added in the last step.

    couldWeOpenUrl = [(YOUR_APP_DELEGATE_CLASS_NAME)self.delegate openURL:url];
    

UIWebView

  1. Implement the 'UIWebView' delegate in the View Controller containing your 'UIWebView'. Override the 'shouldStartLoadWithRequest' forcing it to open the link in your App

    -(BOOL) webView:(UIWebView )inWeb shouldStartLoadWithRequest:(NSURLRequest )inRequest 
    navigationType:(UIWebViewNavigationType)inType 
    {
        if ( inType == UIWebViewNavigationTypeLinkClicked ) 
        {
            [[UIApplication sharedApplication] openURL:[inRequest URL]];
            return NO;
        }
        return YES;
    }
