I am using stringWithcontentsofurl to download some strings from my web server to the App, but i would like to update the UI to show A loader of some kind. I am downloading a number of strings (it can be sometimes as much as 100) so it would be neat for the user to show something so they know the App isn’t crashing, because now the UI is stuck, i can’t show A UILoader or something like that. Is there an option to do so? Or maybe A alternative to stringWithcontentsofurl where this is possible?

greets,
Erik

    This is a classic case for “Lazy Loading”. See Apple’s example code:

    http://developer.apple.com/library/ios/#samplecode/LazyTableImages/Introduction/Intro.html

    It should be easy to substitute “strings” for “images” as you read that code.

    You want to display a placeholder in the label like “(fetching information)” or similar and then load the information in the background, either threading the fetches yourself (asynchronous fetching) or using a library like ASIHTTPRequest that handles all the asynchronous nuts and bolts for you, calling a delegate method once the fetch has completed.
