apple docs can avoid strong reference cycle capturing weak reference self, this: - (void)configureblock { xyzblockkeeper * __weak weakself = self; self.block = ^{ [weakself dosomething]; // capture weak reference // avoid reference cycle } } yet when write code, compiler tells me: dereferencing __weak pointer not allowed due possible null value caused race condition, assign strong variable first yet doesn't following code create strong reference cycle, , possibly leak memory? - (void)configureblock { xyzblockkeeper *strongself = self; self.block = ^{ [strongself dosomething]; } } you should use one: eg: __weak xyzblockkeeper *weakself = self; self.block = ^{ xyzblockkeeper *strongself = weakself; if (strongself) { [strongself dosomething]; } else { // bummer. <self> dealloc before run code. } }
