- Thread-topic: removing all sublayers from a layer with fast enumeration
To remove all sublayers from a layer, it is sufficient to set that layer's
sublayers property to nil, so this code is completely unnecessary. But I'm
just curious as to why it doesn't work:
for (CALayer* sub in myview.layer.sublayers)
[sub removeFromSuperlayer];
This crashes as if the fast enumeration itself were somehow illegal. Why?
Thx -
m.
