How to load images in uitableview?

In my application i m using webservices to get the the image to load in UITableView. the images loaded in the cell and i scroll down to see other datas, if i again scroll up to see already loaded data, there the loaded images are again loading. Why this happens. can anyone tell开发者_开发问答 that how to display images in LazyTableImage example

If we scroll, each time cellForRowAtInpdex is called every time.so,you should handle the image loading in someother part(say ViewDidLoad)..
