how to filter multiple string in NsmutableArray

Question

Hi everyone in my projects i having the NSMutableArray containing a Number of Dictionary value,here i filtered by one string, but now i want to filter a multiple strings in this array,that is below is my Array Value

(
        {
        BusAC = "A/C";
        BusFare = 550;
        BusType = "Semi Sleeper";
        TravelsName = "ABC Travels";
    },
        {
        BusAC = "Non A/C";
        BusFare = 600;
        BusType = Seater;
        TravelsName = "Arulmigu Aandal Azahagar Madurai Express";
    },
        {
        BusAC = "A/C";
        BusFare = 1250;
        BusType = Sleeper;
        TravelsName = "GSP  Travels";
    },
        {
        BusAC = "Non A/C";
        BusFare = 350;
        BusType = "Semi Sleeper";
        TravelsName = "Madura  Travels";
    },
        {
        BusAC = "A/C";
        BusFare = 420;
        BusType = Seater;
        TravelsName = "MJT Travels";
    },
        {
        BusAC = "A/C";
        BusFare = 1500;
        BusType = Sleeper;
        TravelsName = "OPR Travels";
    },
        {
        BusAC = "Non A/C";
        BusFare = 730;
        BusType = Seater;
        TravelsName = "MJT Travels";
    }
)

in this i filtered by one string like Sleeper buses

NSPredicate *predicateStr1 = [NSPredicate predicateWithFormat:@"%K == %@", @"BusType",@"Sleeper"];
 NSMutableArray *filteredArray1 = [NSMutableArray arrayWithArray:[totDictArray filteredArrayUsingPredicate:predicateStr1]];

then i filtered by two string like Sleeper & AC

NSPredicate * prediStr=[NSPredicate predicateWithFormat:@"BusType == %@ AND BusAC == %@",@"Sleeper",@"A/C"];

this also working good but now i want to filter like having array & string

String is A/C & Array value is (
    "ABC Travels",
    "GSP  Travels"
)

i tried this code here the arr is the Above mentioned array

 for (int i=0; i<arr.count; i++)
        {
            NSPredicate * prediStr=[NSPredicate predicateWithFormat:@"TravelsName == %@ AND BusAC == %@",arr[i],@"A/C"];
            NSLog(@"prediStr %@",prediStr);
            NSMutableArray *filteredArray = [NSMutableArray arrayWithArray:[totDictArray filteredArrayUsingPredicate:prediStr]];
                NSLog(@"filteredArray %@",filteredArray);
        }

help me..

        Dropping = "Omini BS";
        TravelsName = "MJT Travels";
    }
)

To determine if a value is found in an array, you use the IN operator.

[NSPredicate predicateWithFormat:@"TravelsName IN %@", array];

thank you so much it working..i need to know more about NSPredicate.

Just wait until you finally understand SUBQUERY(). It opens up whole worlds :)

hi i have another doubt also in that i'm having boarding it's a array value means how to i filter it

Avi Over a year ago

Ask in a separate question or modify this one. I can't tell what you mean without an example.

Avi Over a year ago

The simplest thing to do is build a compound OR predicate, where each subpredicate uses IN. I'm sure there's a better way, but I'm too busy to work it out at this time.
