ios: self becomes nil in block?

Question

I have a view controller, which calls several async network ops (I am using AFNetworking), and handles the response using blocks. Consistently - one of the blocks shows me that self == nil, but other blocks in the SAME view controller, using the same underlying AFNetworking client, show me that self != nil and behave as expected.

Why does this particular block gives me a nil self reference? Am I doing anything wrong? I tried googling for this symptom, in vain.

My View controller is compiled with ARC, testing on iOS 6.1 simulator...

Sounds as if there was an inconsistent `weak` vs. `strong` usage - but then again, without the code this is just guessing. — Till, Aug 12 '13 at 11:47

Instead of accessing self directly, you should access it indirectly, from a reference that will not be retained. for more..
