self.view.subviews not showing buttons

Question

I want to iterate through all of the subviews in my view, and do something for each UIButton. This is the code i'm using (in the end of the viewDidLoad):

for(UIView* v in self.view.subviews)
{
    if([v isKindOfClass:[UIButton class]])
    {
        NSLog(@"This is a button");
        //DO SOMETHING FOR EACH BUTTOn
    }
}

But the problem is that the "This is a button" line is never reached...

Why is that?

Are the buttons direct subviews or contained in another subview? — Wain, Jun 11 '13 at 06:47
Just thought of that - I'll try to add else if([v isKindOfClass:[UIView class]]) and drilldown. Should solve the problem. I hope... — YogevSitton, Jun 11 '13 at 06:50
Is there a way to get all UIButtons no matter where they are? — YogevSitton, Jun 11 '13 at 06:53
Try using recursive function - http://stackoverflow.com/questions/2746478/how-can-i-loop-through-all-subviews-of-a-uiview-and-their-subviews-and-their-su — rshankar, Jun 11 '13 at 07:03

self.view.subviews will return only the subviews of that view.

For eg. View A->View B ->view C

Subviews of View A will list only View B,View C will be only available as the subview of view B

So try some recursive method to drilldown into all the subviews
