Question

Simply use symbolic break point like -[EntityName setAttribute:] doesn’t work.

Answer 1

Dwayne,

Core Data accessors aren’t tricky but they aren’t standard either. If you want to catch one, and still have CD operate properly, the accessor needs more support than Mundi lists above. (His answer is correct in design and intent, just not complete.)

...
@property (nonatomic) NSString *primitiveStringAttribute;
...
@dynamic stringAttribute, primitiveStringAttribute;
...
- (NSString *) stringAttribute {

  NSString *attribute = nil;

  [self willAccessValueForKey: @"stringAttribute"];

  attribute = self.primitiveStringAttribute;

  [self  didAccessValueForKey: @"stringAttribute"];

  return attribute;
}
