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

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
