Fix DBValidationNumberRangeRule

[huunam09]

I was replace this line NSNumber *numberValue = [self.object valueForKey:self.keyPath]; with NSNumberFormatter *f = [[NSNumberFormatter alloc] init]; f.numberStyle = NSNumberFormatterDecimalStyle; NSNumber *numberValue = [f numberFromString:[self.object valueForKey:self.keyPath]]; if (numberValue == nil) return NO; You can check. Best regards
