There are two new memory management attributes for properties introduced by ARC, strong and weak.
Apart from copy, which is obviously something completely different, are there any differences between strong vs retain and weak vs assign?
From my understanding, the only difference here is that weak will assign nil to the pointer, while assign won’t, which means the program will crash when I send a message to the pointer once it’s been released. But if I use weak, this won’t ever happen, because message send to nil won’t do anything.
I don’t know about any differences between strong and retain.
Is there any reason why should I use assign and retain in new projects, or are the kind of being deprecated?
