How to search text with a multi text query using NSPredicate?

I'm trying to perform a query by multiple values. Unfortunately I can't use the ANY operator because I've to perform a CONTAINS operation.

Exemple:

Obj *foo1 = [Obj objectWithName:@"John" age:42];
Obj *foo2 = [Obj objectWithName:@"Elizabeth" age:21];
Obj *foo3 = [Obj objectWithName:@"Albert" age:17];
Obj *foo4 = [Obj objectWithName:@"Marty" age:54];

NSArray *query = @[@"Joh", @"lizabe", @"arty"];

// This query should return foo1, foo2 and foo4.

I tried something like but it doesn't work :

[NSPredicate predicateWithFormat:@"(name CONTAINS[cd]) IN %@, query];

Any suggestion ?

NSMutableArray *filterArray = [NSMutableArray array];
NSArray *query = @[@"Joh", @"lizabe", @"arty"];
for (NSString *string in query)
{
     [filterArray addObjectsFromArray:[mainArray filteredArrayUsingPredicate:[NSPredicate predicateWithFormat:@"name CONTAINS[cd] IN %@", string]]];
}

Here mainarray is your objects containing array.

or try this..

    NSMutableArray *filterArray = [NSMutableArray array];
    NSMutableArray *predicateArray = [NSMutableArray array];
    NSArray *query = @[@"Joh", @"lizabe", @"arty"];
    for (NSString *string in query)
         [predicateArray addObject:[NSPredicate predicateWithFormat:@"name CONTAINS[c] %@", string]];

   NSPredicate *compoundpred = [NSCompoundPredicate andPredicateWithSubpredicates:predicateArray];
[filterArray addObjectsFromArray:[mainArray filteredArrayUsingPredicate:compoundpred];

I hope this will help for you...
