NSPredicate to match “any entry in an NSDatabase with value that contains a string”

Question

I have an array of dictionaries, similar to the following:

(
        {
            Black = \"?\";
            Date = \"????.??.??\";
            Result = \"*\";
          


        

Answer 1

if you want to match a object in the dictionary the you can do this by using a for loop but it may be a time consuming task -

for(int i=0; i< [array count]; i++)
{

    NSDictionary *dic = [array objectAtIndex:i];

    if([[dic objectForKey:@"Black"] isEqualToString:@"2007"])
    {
    //here is the match
    }
}
