I am making a simple mac os x app, in which I will be showing some records in a table view, after retrieving those from local db. I am using core data and NSArrayController proxy for the same and I am trying to achieve it through cocoa-bindings.
Now I can easily make it working, by performing this binding in NSArrayController proxy: Proxy: NSArrayController Parameters: Managed Object Context Bind to: App Delegate Model Key Path: self.managedObjectContext but I am trying to use NSManagedObjectContext proxy from Interface builder library, for this binding: Proxy: NSArrayController Parameters: Managed Object Context Bind to: Managed Object Context Model Key Path: self I am surprised that there is no binding available for it, in bindings pan. At least there should be a binding to map persistent store coordinator to it. To assign MOC a persistent store coordinator, I am using below code: @property (strong) IBOutlet NSManagedObjectContext*listManagedObjectContext; [self.listManagedObjectContext setPersistentStoreCoordinator:[NSAppDelegate persistentStoreCoordinator]]; Problem is - I am continuously getting this message in console: Cannot perform operation since managed object context has no persistent store coordinator With this stack backtrace: 0 CoreFoundation 0x00007fff8b59fb06 __exceptionPreprocess + 198 1 libobjc.A.dylib 0x00007fff881103f0 objc_exception_throw + 43 2 CoreFoundation 0x00007fff8b59f8dc +[NSException raise:format:] + 204 3 AppKit 0x00007fff907eb5e6 -[_NSManagedProxy _persistentStoreCoordinator] + 81 4 AppKit 0x00007fff907eb528 -[_NSManagedProxy _entity] + 49 5 AppKit 0x00007fff907eb43a -[_NSManagedProxy fetchRequestWithSortDescriptors:limit:] + 95 6 AppKit 0x00007fff90cc04f0 -[NSObjectController(NSManagedController) _executeFetch:didCommitSuccessfully:actionSender:] + 73 My questions are - 1. What is the correct way of using NSManagedObjectContext proxy in interface builder library? 2. How can I resolve observed problem? Please suggest. -- Thanks, Devarshi _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
