show a Facebook user profile image from url to image view

I have a url of image which is fetched by the Facebook profile .I fetch those url and copy in to string "urlpicture" .In url picture my url show but when i pass in "geturl"which is a string type property in another file .when i go in to another file "geturl " is nil.

Thats why i can't show my image on image view.I save image url only in string format .Should i have some thing different to show my image on another view.

         - (void)  loginButton:(FBSDKLoginButton *)loginButton
            didCompleteWithResult:(FBSDKLoginManagerLoginResult *)result
                            error:(NSError *)error
            {
                FBSDKGraphRequest *request = [[FBSDKGraphRequest alloc]
                                              initWithGraphPath:@"/me"
                                              parameters:@{ @"fields": @"id,name,picture,email,gender"}
                                              HTTPMethod:@"GET"];
                [request startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
                    // Insert your code here
                    NSLog(@"%@",result);
                    if ([result isKindOfClass:[NSDictionary class]])
             {    NSDictionary *pictureData  = [result valueForKey:@"picture"];
                        NSDictionary *redata = [pictureData valueForKey:@"data"];
                                _urlpicture = [redata valueForKey:@"url"];

                    }





                }];


                HomeViewController *pushWithSlot=[self.storyboard instantiateViewControllerWithIdentifier:@"HomeViewController"];

                [self.navigationController setViewControllers:@[pushWithSlot] animated:YES];
                pushWithSlot.geturl=_urlpicture;

try this, actually pass the variable before navigation 

HomeViewController *pushWithSlot=[self.storyboard instantiateViewControllerWithIdentifier:@"HomeViewController"];

 pushWithSlot.geturl=_urlpicture;
[self.navigationController setViewControllers:@[pushWithSlot] animated:YES];

the above one is not work, try this the reason is the URl is inside in your block

{    NSDictionary *pictureData  = [result valueForKey:@"picture"];
                    NSDictionary *redata = [pictureData valueForKey:@"data"];
                            _urlpicture = [redata valueForKey:@"url"];

       // call after URL Fetch
                 HomeViewController *pushWithSlot=[self.storyboard instantiateViewControllerWithIdentifier:@"HomeViewController"];

 pushWithSlot.geturl=_urlpicture;
[self.navigationController setViewControllers:@[pushWithSlot] animated:YES];
                }

then try this 

  {    NSDictionary *pictureData  = [result valueForKey:@"picture"];
                    NSDictionary *redata = [pictureData valueForKey:@"data"];
                            _urlpicture = [redata valueForKey:@"url"];

       // call after URL Fetch
                 HomeViewController *pushWithSlot=[self.storyboard instantiateViewControllerWithIdentifier:@"HomeViewController"];

 pushWithSlot.geturl=pushWithSlot;
[self presentViewController:pushWithSlot 
               animated:YES 
             completion:nil];
                }
