I’d like to integrate something like a welcome panel (welcome screen) into our iPhone

  • 0

I’d like to integrate something like a welcome panel (welcome screen) into our iPhone application to inform our users about updates and new offers when they launch the application. I have the following thoughts and doubts:

No user input required

Shows generic HTML without any action from the user point of view, the thing closes after 2 or 3 secs and has a close button if you want to close it manually. This is for advertising and tips.

  • This should be very simple to implement

User input required

Shows generic HTML with an action required from the user point of view, for example a survey. The user should be able to skip it

  • same as above, but is it possible that the user submits something on a HTML page and that causes also something to happen within the iPhone app (maybe via Java Script)? For example the user submits a survey on the HTML page and then app closes the current screen and continues to the next screen (i.e. the real application)?
  • Is it also possible to receive parameters (e.g. an ID) via a HTML website? e.g. if the user receives an offer on the HTML welcome panel, then he clicks on it and it takes him directly to a screen in the iPhone app with content loaded from a server (via JSON) depening on the offer id retrieved through the HTML page.

We prefer implementing it via HTML, because it gives us more flexibility. But I’m also open to hear other suggestions.

Thanks

    UIWebViewDelegate has a method that allows you to respond to interaction in a HTML page:

    - (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType

    Using this, you can catch any links clicked and respond to them in your application by presenting a different view.

    Recieving parameters like an id can be done in a few different ways.

    1) You can parse the HTML and determine it from the source.

    2) You can have a javascript function in the HTML that returns the id. Call it by using

    - (NSString *)stringByEvaluatingJavaScriptFromString:(NSString *)script

    3) You can also use the delegate method I mentioned.

    If you make a link like this: <a href="openInAppOffer_1">get offer</a> you can catch it in the delegate and retrieve the id from the NSURLRequest.

    I hope this will point you in the right direction.
