POPassing an int from MasterView to DetailView in a UISplitViewController
text
Body
copied!<p>I have a UISplitViewController in which i'm attempting to pass an int value from the MasterViewController to a DetailTableViewController. Both the master and the detail view controller are UITableViewControllers. I am attempting to pass the indexPath.row value from the master to the detail which will dictate which array of objects is loaded into the detailViewController's tableview. </p> <p>Some code from MasterViewController.m</p> <pre><code>- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { int indexRowTouched = indexPath.row; detailViewController = [self.splitViewController.viewControllers lastObject]; NSLog(@"%@", detailViewController); detailViewController.detailItem = indexRowTouched; NSLog(@"index row %i", indexRowTouched); } </code></pre> <p>An exception is thrown here</p> <pre><code>detailViewController.detailItem = indexRowTouched; </code></pre> <p>2012-03-28 16:08:19.625 splittest2[14895:f803] -[UINavigationController setDetailItem:]: unrecognized selector sent to instance 0x6b592e0</p> <p>From the DetailViewController.m</p> <pre><code>- (void)setDetailItem:(int)newDetailItem { if (_detailItem != newDetailItem) { _detailItem = newDetailItem; // Update the view. [self configureView]; } if (self.masterPopoverController != nil) { [self.masterPopoverController dismissPopoverAnimated:YES]; } } </code></pre> <p>I also note that the value of detailItem logs "0" as soon as the detailView is loaded, before an indexPath row is selected at all. </p> <p>Im wondering why this property is not being assigned from the MasterViewController, and the TableView is not being updated. </p> <p><strong>EDIT</strong></p> <pre><code>- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { int indexRowTouched = indexPath.row; detailViewController = (DetailViewController *)[[self.splitViewController.viewControllers lastObject] topViewController]; detailViewController.detailItem = indexRowTouched; NSLog(@"index row %i", indexRowTouched); } </code></pre> <p>Trying to access the setDetailItem on the UINavigationController seems to have been fixed by changing the didSelectRowAtIndexPath to the above</p>
