Arc's dealloc is not called

========================================================== =============================== Original blog, for reprinting, please declare the source of e-coffee-Focus on mobile Internet ==================================== ====================================

From the non-arc special arc, we found that the dealloc function was not called. Later, I found thatCodeThe self is referenced, resulting in circular references.

Solution: Use _ weak to reference self. As follows:

Error Code

[_ Svitems addinfinitescrollingwithactionhandler: ^ {[self refreshbottom: Nil];}];

Correct code

_ Weak forumcontentviewcontroller * refself = self; [_ svitems addinfinitescrollingwithactionhandler: ^ {[refself refreshbottom: Nil];}];
