The only possible reason behind this is, Apple would have changed the layer structure of the AlertView or its implementation. That's why you are not able to see the changed color.
So does it mean there is no other way to change the color as in my app I have made everything matched with the app color scheme that is red and black but only dialogs are creating mess with their default blue color I am using xcode 4.2 with storyboard, i've made changes to UIActionSheet but unable to change AlertView background color.
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.
