Your app crashing because BackGrdImage animating only one time after that you releasing the array.
Your app crashing because BackGrdImage animating only one time after that you releasing the array arrayOfImages removeAllObjects; and BackGrdImage. AnimationRepeatCount =3; due to this your image goes animating second time but BackGrdImage does not get arrayOfImages for animation therefore your app going to crash. There is one way when your image animation three time means in 1.5 sec then after you have to call one method for releasing your arrayOfImages.
The above process sure will work out.
May be you are getting memory warning. Because I don't think that device will support images array of 89 images/imageviews. Try debuggig your app on device.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
