php: efficiently running functions with one-time loaded classes multiple times in optional files

由 爱⌒轻易说出口 提交于 2020-01-25 13:56:13
问题 after reading the responses I have rewritten my question. Let's say I have a theoretical php application that uses objects that do different things. For every page that gets loaded by the application, different scripts will be run. now I made a simple php script that creates a simple object. (this is all made up, I'm just trying to understand this before I code it) $user = new userClass($db); $user->login($credentials); all is fine, and I can even repeat the procedure several times after

Loading images on scrollview using lazy loading

由 ◇◆丶佛笑我妖孽 提交于 2020-01-25 11:45:12
问题 I am working on an app in which I need to load nearly 211 images in a scrollview. What I was doing was I was converting the images in binary format (NSData) and saving them in core data. Then retrieving them and populating them on the scrollview. it does work, but sometimes it does throw "Memory warning". I learned that lazy loading is a way to achieve this. But, I am not totally aware of how it is done. Like, loading 3 or 5 images ahead/back of the image visible currently on the scrollview.
