问题
I want to enumerate all the nodes in my scene. Not just the ones that are a child of the scene itself, but also the children of those, and the children of those etc... So I want to be able to go through the whole node hierarchy.
Is there a method to do that without knowing how deep the node tree goes?
回答1:
Yep, use enumerateChildNodesWithName:usingBlock: and pass //* as the node name. You should be able to call that on any node.
It's actually one of the examples in Apple's docs:
//* This search string matches every node in the node tree.
