    newView.layer.borderWidth = 4;

You can always give tags to UIViews inside the FOR Loop first.

for (int i = 0; i < list ; i++) 
{
     UIView  *newView = [[UIView alloc]initWithFrame:CGRectMake(lastPosition, 10, widthValue, 60)];
     newView.tag = i;
     [newView.layer setBorderColor:[[UIColor blueColor] CGColor]];
     [self.view addSubview:newView];
     lastPosition = newView.bounds.size.width + 20;
     newView.layer.borderWidth = 4;

     [newView release];
}

Later on, to access any view you can always get it from their tag.

Supposing we want a view which is at the last element of your array....

UIView* latestView = [self.view viewWithTag:[list count]-1];
