Answer 1

You should create an array of dictionary objects, with each dictionary object containing one image, one sound and one text object (the same name ones). So the array will contain 36 dictionary objects and each dictionary object will contain 3 objects each.

NSMutableArray *combinedArray = [[NSMutableArray alloc] init];
for(i=0;i<36;i++) {
    NSDictionary *dict = [[NSDictionary dictionaryWithObjectsAndKeys:[imageArray objectAtIndex:i], @"image", [textArray objectAtIndex:i], @"text", [soundArray objectAtIndex:i], @"sound", nil]];
    [combinedArray addObject:dict];
}

Now you can use arc4Random on the combinedArray, and you'll have all the 3 corresponding objects at the selected random index. Hope this helps

if you want to store array into dictinoary then write below code.What you do is create 3 different array and then create for loop.

          for(int i=0;i<some value:i++)
          {
            dictMut=[[NSMutableDictionary alloc]init];
            [dictMut setObject:[dataArrayA objectAtIndex:w] forKey:@"A"];
            [dictMut setObject:[dataArrayB objectAtIndex:w] forKey:@"B"];
            [dictMut setObject:[dataArrayC objectAtIndex:w] forKey:@"C"];
          }

let me know it is working or not!!!

Happy Coding!!!!

ok i saw that...Now what you did is you have created textarray, soundarray and imagearray.

Now after create these 3 arrays write code like below..

        for(int i=0;i<36:i++)
      {
        dictMut=[[NSMutableDictionary alloc]init];
        [dictMut setObject:[textarray objectAtIndex:w] forKey:@"A"];
        [dictMut setObject:[soundarray objectAtIndex:w] forKey:@"B"];
        [dictMut setObject:[imagearray objectAtIndex:w] forKey:@"C"];
      }

and your array values will be stored in dictionary.

let me know it is working or not!!!!

HaPPY Coding!!!!
