Push parameter in controller is always null - ios

Question

I'm having a tableview. And in my didselectrow I get the right object that I want to pass to the next controller.
This is my code:
id<NavigateDelegate> strongDelegate = self.delegate;
NSDictionary * dictionary = [_dataArray objectAtIndex:indexPath.section];
NSArray * array = [dictionary objectForKey:#"data"];
POI * poi = [array objectAtIndex:indexPath.row];
NSLog(#"%#", poi);
NSLog(#"Category %#", poi.rank.name);
[tableView deselectRowAtIndexPath:indexPath animated:YES];
DetailsViewController * detailsController = [[DetailsViewController alloc] init];
detailsController.details = [[NSDictionary alloc] initWithObjectsAndKeys:poi.name, #"name", poi.address, #"address", poi.details, #"details", poi.title, #"title", poi.url, #"url", nil];
if ([strongDelegate respondsToSelector:#selector(navigateFromTo:to:)]) {
[strongDelegate navigateFromTo:self to:detailsController];
}
Then in my delegate receiver I push the controller like:
- (void) navigateFromTo:(POITableViewController *)viewController to:(UIViewController *)toController
{
[self.navigationController pushViewController:toController animated:YES];
}
But still my DetailsController his details NSdictionary is null.
What am I doing wrong?

Answer 1

I found the problem. The viewdid load is called before my setter is called.
So I changed the init method like this:
-(instancetype) initWithPoi:(NSDictionary *) poi
{
self = [super init];
if(self)
{
NSLog(#"Init DetailsViewController");
_details = poi;
[self initializeViews];
}
return self;
}
that way the controller has the poi details from the start.
