Forgive me if this has been asked, and I did not perform a good enough search on SO.
I am doing the following to enumerate over an array of subviews, while removing each subview from its superview:
for( NSView *subview in [[self subviews] copy])
{
[subview removeFromSuperview];
}
It works fine, but is there a more appropriate way to implement this loop, rather than simply copying the array?
NSView's subviews getter directly returns it's mutable array without copying it. So if you want to remove specific subviews the way of doing it is to copy it. Otherwise in your specific case, since you want to remove all subviews, you can just set it's subviews to be an empty array:
[self setSubviews: @[] ];
This is an option
for (int i = self.subviews.count - 1; i >= 0; --i) {
UIView* v = self.subviews[i];
[v removeFromSuperview];
}
