I now have a grid of 25 cloned buttons with background pictures set to unique images pulled from an AirTable spreadsheet. But updating those 25 images (and associated names; this is a student directory app) on the fly is proving slow. It takes about 5 seconds on an iPhone 8 to refresh the screen with updated content.
Is there a way I can pull images from AirTable and store them locally on the device? Ideally, the user (teacher) would download the entire spreadsheet from AirTable on first run and then not have to access the spreadsheet ever again unless the data was updated by an administrator who sent a push notification about an available update.
I also read something about a 50 MB limit to local storage. Is that still the case? That seems awfully low but I think I could get away with that limit if it still exists. My photos come in at about 30 MB total.
