Get the Array list based on the duplicate values in that Array Objective C. I need to get the array based on the PImg. For example if PImg = 412.jpg. i need the array something lik below

                               {
                                   Id = 8;
                                   Img = "400.jpg";
                                   PImg = "412.jpg";
                                   PQ = "S-30";
                               },
                               {
                                   Id = 9;
                                   Img = "400.jpg";
                                   PImg = "412.jpg";
                                   PQ = "M-30";
                               }

I have only done like getting the duplicates from the response

NSMutableDictionary * thisRow = [resultArray objectAtIndex:0];
NSMutableArray  *pdctDtls = [thisRow objectForKey:@"CarrOptions"];

NSOrderedSet *orderedSet = [[NSOrderedSet orderedSetWithArray:pdctDtls] valueForKey:@"PImg"];
NSMutableArray *newarray = [orderedSet mutableCopy];

In newarray am getting the duplicate values. but if in the newarray if 412.jpg get the array related to 412.jpg. TIA

Try this. If you pass 611.jpg, you get 3 objects.

NSPredicate *predicate = [NSPredicate predicateWithFormat:@"SELF CONTAINS[c] %@", @"611.jpg"]; // AS PER YOUR REQUIREMENT
NSArray *array =[pdctDtls filteredArrayUsingPredicate:predicate];
