I want to store all images url and show in uiscrollview in tableview cell. Please suggest me.

Answer 1

where is the complication?

Parse the XML to get all urls. Put these urls in a NSArray . Now feed this NSArray as a datasource to a UITableView instance. Make sure the UITableViewCell has a UIImageView in it so that you can insert the image urls when scroll happens. Thats it, this is all there is to it.

One more important point, assigning url to uiimageview in main UI thread will hang the UI as it is downloading the image in the main thread. So you will have to do the image downloading in a spawned background thread and then once the image has been downloaded update the uimageview in the main UI thread. This way the user experience would be smooth.
