Question

I have a tableview and a detailview and I can pass data from my tableview to the detail view by including the detail view.h and setting some values from distance with initWithNib.

DetailView *detailView = [[DetailView alloc] initWithNibName:@"DetailView" bundle:[NSBundle mainBundle]];

//passing data gekozenSpel

detailView.gekozenSpel = [tableData objectAtIndex:indexPath.row];

But now I have a data table with multiple entries and one of then is set, that is: can be changed, in the detailview, from 0 to 1 or from 1 to 0, as a string. It works all fine but now I want to apply the change backwards to the table view and that doesn’t work.

myTableView *myTableview = [[myTableView alloc] initWithNibName:@"myTableView" bundle:[NSBundle mainBundle]];

[myTableView.theTable replaceObjectAtIndex:location withObject:value];

For if you use an initWithNib way-of-doing then you create a new empty table nsmutablearray. But I want to CHANGE a value in that array at a specific location with a specific content.

Maybe a singleton to access the data from everywhere? I tried but I have to create instances of what I declare as value and then it is private and not public. So I don’t understand how you apply a singleton then.

Any help would be appreciated,

Answer 1

I replace in the detail view the property (eigenschap) of the heart symbol (favourite: YES or NO), then that whole array is put over the mother array (dataVoorMijnTabel) to have it updated back into the main table view (mijnTabelView).

[eigenschappendata2 replaceObjectAtIndex:locatiehartje withObject:eigenschaphartje];

mijnTabelView *mtb = [[mijnTabelView alloc] initWithNibName:@"mijnTabelView" bundle:[NSBundle mainBundle]];

mtb.dataVoorMijnTabel = eigenschappendata2;
