delegate gets null when performWithSegue - objective-c

Question

Im trying to send some info from a modal view to a delgate. But it seems like my delegate doesnt follow through, it gets null. It looks like this in IB http://i.imgur.com/7oaxb.png.
But it works if i remove the navigationController that is right before the modal view and use the buttons in the View.
please help, ive tried for like 5 hours... :/
Heres the modalViewController code:
#import
#import "Link.h"
#protocol modalViewDelegate <NSObject>
-(void)closeview;
-(void)saveLink:(Link *)link;
#end
#interface modelViewController : UIViewController
#property (weak, nonatomic) IBOutlet UITextField *titel;
#property (weak, nonatomic) IBOutlet UITextField *url;
#property (nonatomic, weak) id <modalViewDelegate> delegate;
- (IBAction)exitModal:(id)sender;
- (IBAction)saveLink:(id)sender;
#end
and .m:
#import "modelViewController.h"
#interface modelViewController ()
#end
#implementation modelViewController
#synthesize titel;
#synthesize url, delegate;
- (IBAction)exitModal:(id)sender {
//[self.delegate closeview];
[self dismissModalViewControllerAnimated:YES];
}
- (IBAction)saveLink:(id)sender {
if (titel.text.length > 0 && url.text.length > 0) {
NSString *urlen = [NSString stringWithFormat:#"%#", url.text];
Link *linken = [[Link alloc] initWithURL:[NSURL URLWithString:urlen]];
linken.title = titel.text;
NSLog(#"%#", delegate); **//returns null when pressing button** it returns null if i put it in viewDidLoad to..
[self.delegate saveLink:linken];
[self dismissModalViewControllerAnimated:YES];
} else {
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:nil message:#"warning" delegate:self cancelButtonTitle:#"ok" otherButtonTitles:nil, nil];
[alertView show];
}
}
#end
the MasterViewController .h (that pushes the modalview:
#import <UIKit/UIKit.h>
#import "modelViewController.h"
#class DetailViewController;
#interface MasterViewController : UITableViewController <modalViewDelegate>
....
and .m
#import "MasterViewController.h"
#import "DetailViewController.h"
#implementation MasterViewController
#synthesize detailViewController = _detailViewController;
#synthesize links;
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if ([segue.identifier isEqualToString:#"linkPush"]) {
// Skicka länken till detaljvyn
DetailViewController *detailVC = segue.destinationViewController;
detailVC.link = [self.links objectAtIndex:self.tableView.indexPathForSelectedRow.row];
NSLog(#"%#", detailVC);
}
//this is the modalview "pusher"
if ([segue.identifier isEqualToString:#"newLink"]) {
modelViewController *mvc = segue.destinationViewController;
mvc.delegate = self;
NSLog(#"%#", mvc.delegate);
}
}
- (void)closeview {
[self dismissModalViewControllerAnimated:YES];
//[self.tabBarController dismissModalViewControllerAnimated:YES];
}
-(void)saveLink:(Link *)link{
NSLog(#"hello");
[links insertObject:link atIndex:links.count]; //updates a Tableview and works fine if delegate is called
[self.tableView reloadData];
//[self dismissModalViewControllerAnimated:YES];
}

If your destination view controller is wrapped into a navigation controller, you have to refer to it differently in prepareForSegue:
UINavigationController *nav = segue.destinationViewController;
DetailViewController *dvc = [nav.viewControllers objectAtIndex:0];
Now setting the properties, including the delegate, should work.
