NSNull handling for NSManagedObject properties values

Question

I\'m setting values for properties of my NSManagedObject, these values are coming from a NSDictionary properly serialized from a JSON file. My problem

Answer 1

I was stuck with the same problem, found this post, did it in a slightly different way.Using category only though -

Make a new category file for "NSDictionary" and add this one method -

@implementation NSDictionary (SuperExtras)

- (id)objectForKey_NoNSNULL:(id)aKey
{
    id result = [self objectForKey:aKey];

if(result==[NSNull null])
{
    return nil;
}

return result;

}

@end

Later on to use it in code, for properties that can have NSNULL in them just use it this way -

newUser.email = [loopdict objectForKey_NoNSNULL:@"email"];

Thats it
