How to use the NSPredicate for searching a string inside the array in dictionary, in array of dictionaries?

Question

Hi I have a Array like this:

@[
    @{@"Name":@"marko"; @"ids"=@[@"121",@"156",@"175",@"154"];},
    @{@"Name":@"shine";@"ids"=@[@"175",@"165",@"154",@"187"];},
    @{@"Name":@"David";@"ids"=@[@"857",@"297",@"156",@"254"];},
    @{@"Name":@"Harry"; @ids"=@[@"297",@"154",@"867",@"201"];},
];

How to get the dictionaries having the string @"156" in the ids array using an NSPredicate.

Have a look at this similar question: http://stackoverflow.com/questions/958622/using-nspredicate-to-filter-an-nsarray-based-on-nsdictionary-keys — Pieter Kuijpers, Sep 25 '15 at 12:53

Try this out:

NSDictionary *dict1 = @{@"Name": @"marko", @"ids" : @[@"121",@"156",@"175",@"154"]};
NSDictionary *dict2 = @{@"Name":@"shine", @"ids" : @[@"175",@"165",@"154",@"187"]};
NSDictionary *dict3 = @{@"Name":@"David", @"ids" : @[@"857",@"297",@"156",@"254"]};
NSDictionary *dict4 = @{@"Name":@"Harry", @"ids" : @[@"297",@"154",@"867",@"201"]};

NSArray *test = @[dict1, dict2, dict3, dict4];

NSArray *filtered = [test filteredArrayUsingPredicate:[NSPredicate predicateWithFormat:@"ids CONTAINS[cd] %@", @"156"]];
