Question

I have not clear how Objective C handle the local and member variable, as I am new to this.
Consider I am creating a view inside a function like this…

fun () {
   new_class *var = [new_class alloc] init]

   // some code to push the view here...
}

everything works fine here, now my question is var is a local variable, when the function scope ends, will it die or not? if it dies how the view is working properly when I am doing some action in it…

thanks…

Answer 1

The var should be release, if it doesn’t have other objects point at it. The thing is:

if it dies how the view is working properly when I am doing some action in it

If your “var” is an UIView for instance, and you [self.view addSubview:var], now you have two objects pointing at it: *var and your self.view, that’s why everything is ok.
