使用MKMapView进行NSRangeException，在主线程上初始化

我有一个奇怪的问题：当我在我的应用程序中更改语言时，一切似乎都没问题，但有时当我连续执行4次以上时，我有一个错误：2014年 -

虽然一切都与MKMapView相关，我在主线程中做了什么。

我知道这种情况并不常见，正常的应用用户在几秒钟内没有超过4次更改语言，但它仍然给我一个错误。

更改语言：

Settings.m：

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    [self.TableViewLanguage deselectRowAtIndexPath:indexPath animated:YES];

    switch (indexPath.row)
    {
        case kLANG_HEB:
            userLang = kHEB;
            [defaults setObject:@[@"he", @"en"] forKey:@"AppleLanguages"];
            break;
        case kLANG_ENG:
            userLang = kENG;
            [defaults setObject:@[@"en", @"he"] forKey:@"AppleLanguages"];
            break;
        case kLANG_RUS:
            userLang = kRUS;
            [defaults setObject:@[@"ru", @"en"] forKey:@"AppleLanguages"];
            break;
        case kLANG_ARAB:
            userLang = kARAB;
            [defaults setObject:@[@"ar", @"en"] forKey:@"AppleLanguages"];
            break;
        case kLANG_FRA:
            userLang = kFRA;
            [defaults setObject:@[@"fr", @"en"] forKey:@"AppleLanguages"];
    }

    [defaults setValue:userLang forKey:@"language"];
    [defaults setBool:YES forKey:ComeFromChangeLang];
    [defaults synchronize];


    if ([appDelegate.window.rootViewController isKindOfClass:[SplashScreen class]]) {
        [self.navigationController popToRootViewControllerAnimated:YES];
    }
    else {
        SplashScreen *viewController = [self.storyboard instantiateViewControllerWithIdentifier:@"ViewController"];
        UINavigationController *nc = [[UINavigationController alloc] initWithRootViewController:viewController];

        MainMap *mapViewController = [self.storyboard instantiateViewControllerWithIdentifier:@"MainAppScreen"];
        mapViewController.mapView.delegate = nil;

        dispatch_async(dispatch_get_main_queue(), ^{
