ios - How can you tell if a MagicalRecord operation was successful? -

i make heavy use of magicalrecord fetching, deleting, updating , saving data. have noticed in testing don't expected results because went wrong operation attempting, such bad predicate resulting in no record being updated or deleted, etc.

i have looked @ available docs (such are) , can find nothing give method examining return code, etc.

anyone know of place lists all of available mr methods with explanations (other mr categories , core)?

i'm not sure you're looking in way of documentation. primary reason sparse documentation project core data docs cover vast majority of features. magical record merely set of convenience methods make standard operations in core data more manageable.

the parts 'non standard' core data functionality may need explanation in how things work, source available read , understand. if have specific question, please ask it.
