Hello,
The (prototype) code below updates a number of objects of a
NSManagedObject-sublass (Progenitor) from a remote host. As the number of
objects to update is unknown I would like to use a call-back passed to the
updater class invoked by startParserWithObjectId: completionBlock: to
recursively call returnblock on the next progenitor-object, so serially, when
the update-task has completed.
However, the static analyser gives me the warning : "Variable 'returnblock' is
uninitialized when captured by block". It is unclear to me how to interpret the
message. Can anyone shed light on it?
NSEnumerator __block *collectionEnum = [progenitors objectEnumerator];
Progenitor *firstProgenitor = [collectionEnum nextObject];
void (^returnblock)(Progenitor *) = ^(Progenitor *aProgenitor) {
if (aProgenitor == nil) return;
CellUpdater *aCellUpdater = [[CellUpdater alloc] init];
[aCellUpdater
setThisPersistentStoreCoordinator:thisPersistentStoreCoordinator];
[aCellUpdater startParserWithObjectId:[aProgenitor objectID]
completionBlock:^(NSManagedObjectID *anID) {
[[NSNotificationCenter defaultCenter]
postNotificationName:@"updateExistsForProgenitor" object:anID];
returnblock([collectionEnum nextObject]);
}];
};
returnblock(firstProgenitor);
Thanks,
Mikkel
