NSPredicate’s predicateWithFormat method takes a va_list of arguments, so it’s not possible to pass an array to your format string. But, the same result can be achieved by combining multiple NSPredicates together using an NSCompoundPredicate:
Given a space-separated array of search words:
NSArray<NSString*> *words = [@"my search terms" componentsSeparatedByString:@" "];
You can combine them by first creating multiple predicates:
NSMutableArray<NSPredicate *> *predicates = [NSMutableArray new];
for (NSString *word in words) {
NSPredicate *predicate = [NSPredicate predicateWithFormat:@"attribute CONTAINS[cd] %@", word];
[predicates addObject:predicate];
}
And finally create one NSPredicate via NSCompoundPredicate
NSPredicate *finalPredicate =
[NSCompoundPredicate andPredicateWithSubpredicates:predicates];
