Question

I have a text view, which has links to web pages, like Wikipedia. Usually when I click on the links it closes my app and opens up Safari.

How do I control the hyperlink, so it loads the web page in the UIWebView instead of Safari?

Putting a button over the link isn’t what I want, because it is a scrollable text view.

Is there a Void I can call, because I also need to start showing the web view when the link is clicked.

Thanks. Any answers would be appreciated.

You can register your app as a URL handler for some URL scheme – for example “nttp”.
Add the next lines in your Info.plist file:

<key>CFBundleURLTypes</key>
<array>
    <dict>
        <key>CFBundleURLName</key>
        <string>com.test.nttp</string>
        <key>CFBundleURLSchemes</key>
        <array>
            <string>nttp</string>
        </array>
    </dict>
</array>

When you write the content for your text view use the “nttp” URL scheme instead of the “http” (“nttp://www.stackoverflow.com/” instead of “http://www.stackoverflow.com/“).

Implement the application:handleOpenURL: method in your app delegate:

- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url {

NSString *aUrl = [url absoluteString];

// Use the URL

return YES; }

For example, you can replace the “nttp” by “http” and initiate some web view with it…

Hope that this solution is good enough…
