ios - What is a better way to load and unload on UIImageVIews -



ios - What is a better way to load and unload on UIImageVIews -

good day all. need help in understanding if doing right thing or not on subject of uiimageviews.

scenario:

i have mainviewcontroller , 3 uiviewcontrollers.

each of 3 viewcontrollers has @ to the lowest degree 20 uiimageviews. png files around 20-30kb each , of them has transparent parts , not in array.

when 1 of 3 viewcontroller loads, alloc , init uiimageviews images.

using buttons, phone call array of bools turn images on or off go pages pages - around 7-10.

it works find working bit slow when loaded on iphone.

queries:

any improve way of doing based experiences?

will improve if utilize 7-10 view controllers load needed in scene? (i needed half of per scene on average understanding using viewcontrollers "heavier")

any reading material or link may lead me answering issue?

when go mainviewcontroller using modal segue, uiimageviews on current viewcontroller unload automatically? (arc on)

thanks.

ios objective-c uiviewcontroller uiimageview
