I’m trying to use threading to load an image from a url. I have no background code and I’m having trouble getting the NSThread thing to work. What I’ve got is a UIimageView called photo1 and I’ve got an image that loads in from the net. (say http://www.google.com/logos/classicplus.png) but when navigating to the screen, the app pauses to load the image before hand. I was told to use NSThread to achieve this (watching the stanford U tutorial on it) but I’m having no luck at all getting it to work.

Any help would really be appreciated.

    I would suggest that you don’t use an NSThread to accomplish this, but rather use an asynchronous NSURLConnection.

    Using the asynchronous URL connection won’t block the UI, but will be much easier to use than maintaining all the boilerplate code required for an NSThread.

    Look up the documentation for NSURLConnection, the parts you’re interested in mainly are the bits on how to create an asynchronous connection and the delegate call backs.
