- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if ([[segue identifier] isEqualToString:@"showDetail"]) {
NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow]; // Sets the index path
NSString *object = [ _titlesArray objectAtIndex: [ indexPath row ] ]; // Sets the title of blog as the variable object
// You need to cast the destination view controller as a DetailViewController, or else it'll give an ugly error...
DetailViewController *controller = (DetailViewController *)[[segue destinationViewController] topViewController];
[controller setDetailItem:object];
/* This just sets the nav bar of the destination view controller to have a button that can change the display of the view controller.
Only introduced in iOS 8
*/
controller.navigationItem.leftBarButtonItem = self.splitViewController.displayModeButtonItem;
controller.navigationItem.leftItemsSupplementBackButton = YES;
}
}
