Syntax

CONTAINS operator : It allows to filter objects with matching subset. `NSPredicate *filterByName = [NSPredicate predicateWithFormat:@"self.title CONTAINS[cd] %@",@"Tom"];`

LIKE : Its simple comparison filter. `NSPredicate *filterByNameCIS = [NSPredicate predicateWithFormat:@"self.title LIKE[cd] %@",@"Tom and Jerry"];`

= operator : It returns all the objects with matching filter value. `NSPredicate *filterByNameCS = [NSPredicate predicateWithFormat:@"self.title = %@",@"Tom and Jerry"];`

IN operator : It allows you to filter objects with specific filter set. `NSPredicate *filterByIds = [NSPredicate predicateWithFormat:@"self.id IN %@",@[@"7CDF6D22-8D36-49C2-84FE-E31EECCECB79", @"7CDF6D22-8D36-49C2-84FE-E31EECCECB76"]];`

NOT IN operator : It allows you to find Inverse objects with specific set. `NSPredicate *filterByNotInIds = [NSPredicate predicateWithFormat:@"NOT (self.id IN %@)",@[@"7CDF6D22-8D36-49C2-84FE-E31EECCECB79", @"7CDF6D22-8D36-49C2-84FE-E31EECCECB76"]];`
