I have 2 scroll views. When click one of the buttons in the first Scroll view, some images related to this button will be retrieves from a plist and loaded into the second Scroll view.Is it possible to use something like "reloadData" between the 2 scroll views in iOS to keep the data loaded efficiently? Customers may click the buttons in the first Scroll view frequently, so we have to consider its efficiency and low system cost. Some sample code is appreciated. thanks!
