Status:Closed Resolved:YES
Product:iOS SDK Product Version:iOS 7.0.x
Classification:Enhancement Reproducible:Always
 
Summary:
For check if two NSManagedObject are equals the correct way today is to write

[[[manObj1 objectID] URIRepresentation] isEqual:[[manObj2 objectID] URIRepresentation]]

It's a bit odd that the NSManagedObject don't already override isEqual: to  do that so we can write only

[manObj1 isEqual:manObj2]

Steps to Reproduce:
1. Get two NSManagedObject subclass that point to the same entry in the database but are created from two different CoreData stack (they must have two different memory address)
2. Call [manObj1 isEqual:manObj2]
3. Call [[[manObj1 objectID] URIRepresentation] isEqual:[[manObj2 objectID] URIRepresentation]]

Expected Results:
The methods at the point 2 and 3 return YES

Actual Results:
The method at point 2 return NO and the one at point 3 return YES

Version:
iOS 7.0.x
