Hi, I read a little bit source codes and found out that Symbol is implemented on top of NSString. My question is if it's a better choice to use SEL as the basis when objc is available? objc runtime takes care of the registration and management. I guess using NSString class is a decision with good reasons, could anybody please shine some lights on it? Thanks Best wishes Linan
