TableViewController will not segue to detail view - ios

Question

I've implemented this tutorial into my project but the segue just won't work! I have tried everything but the cell just stays highlighted when you click it. I have tried adding an identifier to the push - no difference. My tab bar is added programmatically in my appdelegate - could that be it? ALSO the tableview refuses to fit on the screen properly, it overlaps over the status bar (tried pretty much everything for that too).

Here is the debug log:

Answer 1

If you use segue maybe this code can help:
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
// Assume self.view is the table view
NSIndexPath *path = [self.tableView indexPathForSelectedRow];
DetailObject *detail = [self detailForIndexPath:path];
[segue.destinationViewController setDetail:detail];
}
From here: Use didSelectRowAtIndexPath or prepareForSegue method for UITableView?

Transition betweent viewcontroller, you should have a navigation controller.
//Specify viewcontrollers for each tab
MapViewController *mvc = [[MapViewController alloc]init];
TableViewController *evc = [[TableViewController alloc]init];
AboutViewController *avc = [[AboutViewController alloc]init];
UINavigationController* mvcNavi = [[UINavigationController alloc] initWithRootViewController: mvc];
UINavigationController* evcNavi = [[UINavigationController alloc] initWithRootViewController: evc];
UINavigationController* avcNavi = [[UINavigationController alloc] initWithRootViewController: avc];
[tbc setViewControllers:[NSArray arrayWithObjects: mvcNavi, evcNavi, avcNavi, nil]];
And you should implement in your tableview the method :
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
//Alloc/init detailView
UIViewController *detailView = [UIViewController alloc]init];
detailView.restaurantDetail = [self.googlePlacesArrayFromAFNetworking objectAtIndex:indexPath.row];
[self.navigationController pushViewController:detailView animated:YES];
}
p/s: When you create view programatically, you dont change your view by segue, so remove prepareForSegue
