How to set action and event handling for UIIBarButtonItem with custom view (UIButton)?

Problem here is your sender is not your UIBarButtonItem, its the UIButton and you need to remove your UIBarButtonItem, you should keep a referecne to your UIBarButtonItem, and when you receive the click you remove that from the items of the toolbar..

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.
