I am writing to learn more about possible reasons why a cell, containing an image, within a UITableView does not refresh after call to reloadData; rest of row, which contain labels, updates with new data after call to reloadData; Working with a UIPickerView containing two options - default data of UITableView is first option of UIPickerView; if second option of UIPickerView is selected, each row updates, refreshes OK; However, column containing images does not update, refresh - and images remain from initial loading of data; working in debug mode of Objective-C, inside of method cellForRowAtIndexPath - image URLs, to be assigned to cells of UITableView, are available and returned from array;
