I'm getting an error with saving to a Core data object in Xcode.
Xcode says that the error is in the NSDate variable 'datum' but I have tried almost everything.
Error is:
2011-07-12 18:01:29.068 WeekLijstje[3205:207] Core Data Save Error
NSValidationErrorKey datum
NSValidationErrorPredicate (null)
NSValidationErrorObject
<DagLijst: 0x6e2fcd0> (entity: DagLijst; id: 0x6e2fd30 <x-coredata:///DagLijst/t99F423FC-AAE9-4692-9264-EF0FF7A020572> ; data: {
Voedsel = nil;
datum = nil;
hoeveelheid = 0;
punten = 0;
})
NSLocalizedDescription:The operation couldn’t be completed. (Cocoa error 1570.)
A small code snipet:
DagLijst *newDaglijst = [NSEntityDescription insertNewObjectForEntityForName:@"DagLijst" inManagedObjectContext:self.managedObjectContext];
NSDate *selDatum = [NSDate date];
newDaglijst.punten = [NSNumber numberWithInteger:10];
newDaglijst.hoeveelheid = [NSNumber numberWithInt:100];
newDaglijst.Voedsel = geselecteerdVoedsel;
newDaglijst.datum = selDatum;
NSError *error = nil;
if (![newDaglijst.managedObjectContext save:&error]) {
...
Also the class of the DagLijst object:
@interface DagLijst : NSManagedObject {
@private
}
@property (nonatomic, retain) NSDate * datum;
@property (nonatomic, retain) NSNumber * punten;
@property (nonatomic, retain) NSNumber * hoeveelheid;
@property (nonatomic, retain) Voedsel *Voedsel;
@end
So you can see that I put an NSDate into the 'datum' variable. But on execution I still get an error.
