Whenever any row selected related chapeter is being load. I am controlling with different view. I want to know which view is being load in my “pdfReader.m” file. So i will load pdf file for reading. I am loading my view like below code.

..........
.........


    switch (indexPath.row) {
        case 0:
            NSLog(@"!!!!!!");
            pdfReader.view = pdfReader.Chapter1;
            break;
        case 1:
            //pdfReader.view = pdfReader.Chapter2;
            break;
        case 2:
            //pdfReader.view = pdfReader.Chapter3;
            break;

        default:
            break;
    }

}

I want to which view are coming to load in pdfReader.m file.

Answer 1

you need to assign an tag value with each of your view. (When you create your views with init method)

 pdfReader.Chapter1.tag = 1;
 pdfReader.Chapter2.tag = 2;
 pdfReader.Chapter3.tag = 3;

Now modify your didSelectRowAtIndexPath function

    -(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    {

       if(pdfReader.view.tag == 1)
       {
          //First chapter used 
       }
       else if(pdfReader.view.tag == 2)
       {       
            //Second chapter used 
       }
       else if(pdfReader.view.tag == 3)
       {
            //third chapter used 
       }
       ..........................
       ..........................
       ..........................

      switch (indexPath.row)
      {
      case 0:
           pdfReader.view = pdfReader.Chapter1;
        break;
      case 1:
           //pdfReader.view = pdfReader.Chapter2;
        break;
      case 2:
           //pdfReader.view = pdfReader.Chapter3;
        break;

      default:
        break;
     }
   }
