Generic typeof for weak self references

automatic-ref-counting, cocoa, objective-c, objective-c-blocks, weak-references

Solution

This works!

__typeof__(o) __weak

Which I've defined in my BBlock project as `BBlockWeakSelf` which can be used like this:

BBlockWeakSelf wself = self;

Problem

I am trying to figure out a way to use `typeof` to create a weak reference to `self` for use in blocks to avoid retain cycles. When I first read about this it seems that the convention was to use `__block typeof(self) bself = self;`, which compiles but using `__block` to avoid retain cycles doesn't work anymore and `__weak` should be used instead. However `__weak typeof(self) bself = self;` results in an error: The type 'typeof (self)' (aka 'TUAccountsViewController *const __strong') already has retainment attributes set on it Is there a way to use `typeof` or another call to generically create a weak reference to `self`?
