Changing an instance variable in a block

Question

I am quite confused about how to change an instance variable inside of a block.

The interface file (.h):

@interface TPFavoritesViewController : UIVie         


        

Answer 1

Your assignment to refreshing is an implicit reference to self, it is shorthand for:

self->refreshing = YES;

hence the cycle warning. Change it to:

temp_self->refreshing = YES;
