Демонстрация близости маяков Estimote, запускающая ViewController в Immediate Case

Я работаю над оценочным маяком.

Я пытаюсь представить ViewController, когда я нахожусь в случае переключения «немедленно». Но когда я загружаю представление, у меня есть предупреждение:

2014-03-13 02:44:26.017 ProximityDemo[856:60b] Предупреждение: Попытка представить, чье представление не находится в иерархии окон!

Почему ? Я думаю, что метод PresentView все еще работает, пока я нахожусь в новом представлении.

Также, когда я нахожусь в новом представлении, я хотел бы перейти к старому представлению, когда я нахожусь в случае «Рядом»

Думаю, мне нужно реализовать весь код в новом ViewController? (presentProductViewController) Есть ли способ, чтобы все управление близостью/расстоянием осуществлялось только в одном контроллере?

Вот мой код:

ESTViewController:

#import "ESTViewController.h"
#import <ESTBeaconManager.h>
#import "PresentProductViewController.h"

@interface ESTViewController () <ESTBeaconManagerDelegate>

@property (nonatomic, strong) ESTBeaconManager* beaconManager;
@property (nonatomic, strong) ESTBeacon* selectedBeacon;

@end

@implementation ESTViewController

- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.

/////////////////////////////////////////////////////////////
// setup Estimote beacon manager

// craete manager instance
self.beaconManager = [[ESTBeaconManager alloc] init];
self.beaconManager.delegate = self;
self.beaconManager.avoidUnknownStateBeacons = YES;

// create sample region object (you can additionaly pass major / minor values)
ESTBeaconRegion* region = [[ESTBeaconRegion alloc] initWithProximityUUID:ESTIMOTE_IOSBEACON_PROXIMITY_UUID
                                                              identifier:@"EstimoteSampleRegion"];

// start looking for estimote beacons in region
// when beacon ranged beaconManager:didRangeBeacons:inRegion: invoked
[self.beaconManager startRangingBeaconsInRegion:region];



}

-(void)beaconManager:(ESTBeaconManager *)manager
 didRangeBeacons:(NSArray *)beacons
        inRegion:(ESTBeaconRegion *)region

if([beacons count] > 0)
{

    if(!self.selectedBeacon)
    {
        // initialy pick closest beacon
        self.selectedBeacon = [beacons objectAtIndex:0];
    }
    else
    {
        for (ESTBeacon* cBeacon in beacons)
        {
            // update beacon it same as selected initially
            if([self.selectedBeacon.major unsignedShortValue] == [cBeacon.major unsignedShortValue] &&
               [self.selectedBeacon.minor unsignedShortValue] == [cBeacon.minor unsignedShortValue])
            {
                self.selectedBeacon = cBeacon;
            }
        }
    }



    // beacon array is sorted based on distance
    // closest beacon is the first one

    NSString* labelText = [NSString stringWithFormat:

    // calculate and set new y position
    switch (self.selectedBeacon.proximity)
    {
        case CLProximityUnknown:
        {
            labelText = [labelText stringByAppendingString: @"Unknown"];
            break;
        }
        case CLProximityImmediate:
        {
            labelText = [labelText stringByAppendingString: @"Immediate"];

            PresentProductViewController *showViewController = [[PresentProductViewController alloc] initWithNibName:@"PresentProductViewController" bundle:nil];

            [self presentViewController:showViewController animated:YES completion:nil];

            //ESTViewController *initViewController = [[ESTViewController alloc]init];

Я уверен, что делаю неправильно. Спасибо за вашу помощь.
