Going further with the BlogReader project

I am making my iOS app which is mostly based on the BlogReader project but I need some changes in it. Like, I could store the content of the post and display it as HTML. I don't want them to open the website all the time, i.e, I want offline viewing. But when an internet connection IS available, it should update the content.

I was wondering how I could achieve that. If you could give me a little guidance on this topic, it'll be really helpful. I have just began to learn iOS Development. Thank you.

You will want to request the page using its URL, and then use store the HTML response in an NSData object using the dataWithContentsOfURL method, like this answer from StackOverflow: http://stackoverflow.com/a/5607132/475217

That answer also shows how to store the HTML for offline use. There are other options as well, like NSUserDefaults or NSArchiver. NSUserDefaults is a simple way to get started. Here is another example from StackOverflow: http://stackoverflow.com/a/8727555/475217
