View Full Version : refreshObject:mergeChanges for all instances of NSManagedObject in UITableView

I'm using refreshObject:mergeChanges to refresh NSManagedObject "Task" in my UITableView. It works like it should, but I can only get it to refresh a single instance or cell at a time in my UITableView. What I want to be able to do is to use a single method (ex: refreshTasks) to to refresh everything at once.

in my .h file:

@property (strong, nonatomic) Task *selectedTask;

in my .m:

NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
self.selectedTask = [self.fetchedResultsController objectAtIndexPath:indexPath];
[self.managedObjectContext refreshObject:selectedTask mergeChanges:NO];


Now I know I'm refreshing only the selected "Task" but does anyone know how I could either get the indexPath for all of the items in the TableView, or to refresh everything at once?

Any help would be really appreciated. Thank you so much!
