IOS/Objective C: Coredata NSPredicate with boolean

Question

I have a boolean attribute in Coredata named "hide". In the nsmanagedobject file, the variable is an NSNumber.

@property (nonatomic, strong) NSNumber *hide;//bool

In some cases, I want to exclude or "hide" items where the value of hide is 1. The predicate I am using for this is:

hideClause = @"hide != 1";
hidePred =  [NSPredicate predicateWithFormat:hideClause];

However, the logic is not working as expected. The FRC is not returning items even when I know for sure the value of hide is not 1.

Can anyone see what might be wrong?

Use below predicate :

hidePred = [NSPredicate predicateWithFormat:@"hide != %@", [NSNumber numberWithBool:YES]]

Try [NSPredicate predicateWithFormat:@"NOT (hide == %@)", [NSNumber numberWithBool:YES]] – Vinit Ingale Jun 28 '17 at 13:38
