How can I compare two NSNumbers or a NSNumber and an Integer in an NSPredicate?
I tried:
NSNumber *stdUserNumber = [NSNumber numberWithInteger:[[NSUserDefaults standardUserDefaults] integerForKey:@"standardUser"]];
fetchRequest.predicate = [NSPredicate predicateWithFormat:@"userID == %@", stdUserNumber];
Well, this doesn't work ... anyone has an idea how to do it? I'm sure it's pretty easy but I wasn't able to find anything ...
NSNumber
is an object type. Unlike NSString
, the actual value of NSNumber is not substitued when used with %@
format. You have to get the actual value using the predefined methods, like intValue
which returns the integer value. And use the format substituer as %d
as we are going to substitute an integer value.
The predicate should be,
predicateWithFormat:@"userID == %d", [stdUserNumber intValue]];
