Create Array from another Array

Question

I have an array that looks like this:

(
        {
        title = "Chris";
        isMale = 1;
        age = 13;
    },
        {
        defaultTitle = "Jessica";
        isMale = 0;
        age = 15;
    }
)

I want to create another array that contains the dictionaries from the original array where the BOOL isMale is Yes, or 1. How can I do this?

Use a predicate. You can filter an array with the filteredArrayUsingPredicate: method

NSArray *filteredArray = [originalAray filteredArrayUsingPredicate:[NSPredicate predicateWithFormat:@"isMale == %@",[NSNumber numberWithBool:YES]]];
