Multiple Argument pass as index value of the Array iOS

Question

I am developing QRCode application, I am getting some problem to enable barcoding symbologies. I have one array in which I get all barcoding symbologies from websrvice data response, need to be as enable. I apply static code as follow and its working for me. But I want to make it dynamic. Following is my code :

Please help me to make it, dynamic. I tried many approaches but not getting proper solution.

Created two array :

  NSMutableArray *enableSymbologies = [[[NSMutableArray alloc] init] autorelease];  // Data from webservice response   
  NSMutableArray *symbologiesToSet = [[[NSMutableArray alloc] init] autorelease];  // for enabling barcode symbology 

 for (int i =0 ; i < [enableSymbologies count] ; i ++)
        {
            if([[enableSymbologies objectAtIndex:i] isEqualToString:@"Code39"])
            {
                [symbologiesToSet addObject:[NSNumber numberWithInt:MWB_CODE_MASK_39]];
            }
            else if ([[enableSymbologies objectAtIndex:i] isEqualToString:@"Code93"])
            {
                [symbologiesToSet addObject:[NSNumber numberWithInt:MWB_CODE_MASK_93]];
            }
            else if ([[enableSymbologies objectAtIndex:i] isEqualToString:@"Code25I"])
            {
                [symbologiesToSet addObject:[NSNumber numberWithInt:MWB_CODE_MASK_25]];
            }
            else if ([[enableSymbologies objectAtIndex:i] isEqualToString:@"Code25S"])
            {
                [symbologiesToSet addObject:[NSNumber numberWithInt:MWB_CODE_MASK_25]];
            }
            else if ([[enableSymbologies objectAtIndex:i] isEqualToString:@"Code128"])
            {
                [symbologiesToSet addObject:[NSNumber numberWithInt:MWB_CODE_MASK_128]];
            }
            else if ([[enableSymbologies objectAtIndex:i] isEqualToString:@"QR"])
            {
                [symbologiesToSet addObject:[NSNumber numberWithInt:MWB_CODE_MASK_QR]];
            }
            else if ([[enableSymbologies objectAtIndex:i] isEqualToString:@"EAN+UPC"])
            {
                [symbologiesToSet addObject:[NSNumber numberWithInt:MWB_CODE_MASK_EANUPC]];
            }
            else if ([[enableSymbologies objectAtIndex:i] isEqualToString:@"PDF"])
            {
                [symbologiesToSet addObject:[NSNumber numberWithInt:MWB_CODE_MASK_PDF]];
            }
            else if ([[enableSymbologies objectAtIndex:i] isEqualToString:@"CodaBar"])
            {
                [symbologiesToSet addObject:[NSNumber numberWithInt:MWB_CODE_MASK_CODABAR]];
            }

            else
            {
                [symbologiesToSet addObject:[NSNumber numberWithInt:MWB_CODE_MASK_QR]];
            }


    }

what actually happens here MWB_setActiveCodes([[symbologiesToSet objectAtIndex:0] integerValue] | [[symbologiesToSet objectAtIndex:1] integerValue] | [[symbologiesToSet objectAtIndex:2] integerValue]); — Charan Giri, Mar 20 '14 at 13:03
Why do you call `MWB_setActiveCodes` `symbologiesToSet.count` times with the same argument ? — A-Live, Mar 20 '14 at 13:42
Because I want to those number of setActiveCode coming from symbologiesToSet.count. — Divya Bhaloidiya, Mar 20 '14 at 13:48
@Desdenova : I am already use another library that is MobiScan — Divya Bhaloidiya, Mar 20 '14 at 13:49

I got the solution. Here it is ..

if(curEvent.enablescanning == 1)
        {
            if([enableSymbologies count] == 0)
            {
                MWB_setActiveCodes(MWB_CODE_MASK_QR);
            }
            else
            {
                int globalSelectedTypes = 0;
                for (int i =0 ; i < [enableSymbologies count] ; i++)
                {
                    if([[enableSymbologies objectAtIndex:i] isEqualToString:@"Code39"])
                    {
                        globalSelectedTypes = globalSelectedTypes + MWB_CODE_MASK_39;
                    }
                    else if ([[enableSymbologies objectAtIndex:i] isEqualToString:@"Code93"])
                    {
                        globalSelectedTypes = globalSelectedTypes + MWB_CODE_MASK_93;
                    }
                    else if ([[enableSymbologies objectAtIndex:i] isEqualToString:@"Code25I"] || [[enableSymbologies objectAtIndex:i] isEqualToString:@"Code25S"])
                    {
                        globalSelectedTypes = globalSelectedTypes + MWB_CODE_MASK_25;
                    }
                    else if ([[enableSymbologies objectAtIndex:i] isEqualToString:@"Code128"])
                    {
                        globalSelectedTypes = globalSelectedTypes + MWB_CODE_MASK_128;
                    }
                    else if ([[enableSymbologies objectAtIndex:i] isEqualToString:@"QR"])
                    {
                        globalSelectedTypes = globalSelectedTypes + MWB_CODE_MASK_QR;
                    }
                    else if ([[enableSymbologies objectAtIndex:i] isEqualToString:@"EAN+UPC"])
                    {
                        globalSelectedTypes = globalSelectedTypes + MWB_CODE_MASK_EANUPC;
                    }
                    else if ([[enableSymbologies objectAtIndex:i] isEqualToString:@"PDF"])
                    {
                        globalSelectedTypes = globalSelectedTypes + MWB_CODE_MASK_PDF;
                    }
                    else if ([[enableSymbologies objectAtIndex:i] isEqualToString:@"CodaBar"])
                    {
                        globalSelectedTypes = globalSelectedTypes + MWB_CODE_MASK_CODABAR;
                    }
                }

                MWB_setActiveCodes(globalSelectedTypes);
            }
        }
