copied!<p>I have also had a problem with <strong>Attempting to create USE_BLOCK_IN_FRAME variable with block that isn't in the frame</strong>. Although mine wasn't anything to do with NSFetchedResultsControllers.</p> <h2>Possibly Your Problem</h2> <p>I noticed you mention you are using a singleton, so maybe your problem is solved at this link:</p> <p><a href="http://npenkov.com/2011/08/01/solving-issues-like-warning-attempting-to-create-use_block_in_frame-variable-with-block-that-isnt-in-the-frame/" rel="nofollow">http://npenkov.com/2011/08/01/solving-issues-like-warning-attempting-to-create-use_block_in_frame-variable-with-block-that-isnt-in-the-frame/</a></p> <p>From the link:</p> <blockquote> <p>Exactly in session manager I used the macro, before @synthesize – this was the problem, static definitions should not appear before synthesized methods. So if you have something like:</p> </blockquote> <pre><code>SYNTHESIZE_SINGLETON_FOR_CLASS(SessionManager) @synthesize loggedUserId, ... </code></pre> <blockquote> <p>Just replace it with:</p> </blockquote> <pre><code>@synthesize loggedUserId, ... SYNTHESIZE_SINGLETON_FOR_CLASS(SessionManager) enter code here </code></pre> <h2>My problem</h2> <p>The problem I had was to do with duplicating a variable declaration, in this case the variable inherited from NSManagedObject :</p> <pre><code>- (void)functionThatDoesSomething { VariableInheritedFromNSMObj *variableA = nil; for (VariableInheritedFromNSMObj *variableA in [self containerObject]) { NSLog(@"a = %@\n", [variableA name]); } [variableA setName:@"StackOverflow"]; } </code></pre> <p>Moving the first line, where variableA is initialised to nil, to after the loop fixed the problem. In my production code I then changed the name of one of the variables.</p> <p>Hope that helps you or someone else who comes across this problem. This error seems to manifest itself in many different ways.</p>
