ios - Preserving Images In an IBOutletCollection -


here code far:

@iboutlet var boxes: [uiimageview]! @ibaction func success(_ sender: any) {     if "" == defaults.value(forkey: "frequency") as? string{         box in boxes{             if box.image == uiimage(named:"blank.png"){                 box.image = uiimage(named:"arm.png")                 break             }         }     }     else if "twice" == defaults.value(forkey: "frequency") as? string{         box in boxes{             if box.image == uiimage(named:"arm1.png"){                 box.image = uiimage(named:"arm.png")                 break             }             else if box.image == uiimage(named:"blank.png"){                 box.image = uiimage(named:"arm1.png")                 break             }         }         }  }

the defaults.value(forkey: frequency) used determine how user wants change grid. how create userdefaults restore images in grid on app close? (double tap home , swipe up). userdefaults right way this? feel easier, way messier create individual outlet each uiimageview , saving state each 1 through giant tree of code. thank you!

if images stored in bundle (manually added , won't changed) can save names userdefaults instead of saving images. otherwise use database. there nice framework realm. try it. also, store images, better convert them data
