Getting all the selected cells values

My purpose is when the user click on a button in view1 (to go to the view2), i will send all the selected cells from UITableView just checked in view1 to the view2. So before passing the table to next view, i wanted to test if i am on the right track, but seems not. This is my code:

-(IBAction)goToView2{
    //get all section selectioned items into an array
    themesChosed=[tView indexPathsForSelectedRows];//tView is the outlet of my UITableView and themesChosed is an NSArray declared in the .h file
    for (int i=0; i<=[themesChosed count]; i++) {
        NSLog(@"%i",[[themesChosed objectAtIndex:i]integerValue]);
    }


}

This always returning me a single 0.

2012-01-13 15:52:06.472 MyApp[876:11603] 0

Although i selected several items on the table.

If you are not getting index values then best approach wound be as below to access index number:

  NSArray *indexes = [self.tableView indexPathsForSelectedRows];
   for (NSIndexPath *path in indexes) {
     NSUInteger index = [path indexAtPosition:[path length] - 1];
     [selectedOptionsArray addObject:[optionHolderArray objectAtIndex:index]];
  }

The objects in themesChosed are NSIndexPath objects. You'll want to access the row and section properties like so:

-(IBAction)goToView2{
    //get all section selectioned items into an array
    themesChosed=[tView indexPathsForSelectedRows];//tView is the outlet of my UITableView and themesChosed is an NSArray declared in the .h file
    for (int i=0; i<=[themesChosed count]; i++) {
        NSIndexPath *thisPath = [themesChosed objectAtIndex:i];
        NSLog(@"row = %i, section = %i", thisPath.row, thisPath.section);
    }
}

First NSIndexPath is not an integer, it is an object with row and section methods, so that is probably why you get a zero. Are you sure you have allowsMultipleSelection set to YES?
