Question

现在，在用户批准了相机和GPS的权限后，我就拥有带有pois的黑屏。它就像摄像机出现问题一样，因为pois正在移动设备位置变化，所以部分工作得很好，如果我杀了应用程序，然后启动它每一个都很好（用户已经批准了权限）任何想法是什么可能是问题？代码如下：

- (void)viewDidLoad {
    [super viewDidLoad];
    NSError *deviceNotSupportedError = nil;
    if ( [WTArchitectView isDeviceSupportedForRequiredFeatures:WTFeature_Geo error:&deviceNotSupportedError] ) { // 1
        self.architectView.delegate = self;
        [self.architectView setLicenseKey:@""];

        self.architectWorldNavigation = [self.architectView loadArchitectWorldFromURL:[[NSBundle mainBundle] URLForResource:@"index" withExtension:@"html" subdirectory:@"4_PointOfInterest_4_SelectingPois"] withRequiredFeatures:WTFeature_Geo | WTFeature_2DTracking];

        [[NSNotificationCenter defaultCenter] addObserverForName:UIApplicationDidBecomeActiveNotification
                                                          object:nil
                                                           queue:[NSOperationQueue mainQueue]
                                                      usingBlock:^(NSNotification *note) {
                                                          if (self.architectWorldNavigation.wasInterrupted) {
                                                              [self.architectView reloadArchitectWorld];
                                                          }
                                                          [self startRunning];
                                                      }];

        [[NSNotificationCenter defaultCenter] addObserverForName:UIApplicationWillResignActiveNotification
                                                          object:nil
                                                           queue:[NSOperationQueue mainQueue]
                                                      usingBlock:^(NSNotification *note) {
                                                          [self startRunning];
                                                      }];

    } else {
        NSLog(@"device is not supported - reason: %@", [deviceNotSupportedError localizedDescription]);
    }
}

-(void)viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];
    [self startRunning];
}

- (void)startRunning {

    if ( ![self.architectView isRunning] ) {
        [self.architectView start:^(WTStartupConfiguration *configuration) {
            configuration.captureDevicePosition= AVCaptureDevicePositionBack;

        } completion:^(BOOL isRunning, NSError *error) {
            if ( !isRunning ) {
                NSLog(@"WTArchitectView could not be started. Reason: %@", [error localizedDescription]);
            }
        }];
    }
}

在构建设置上为调试和发布设置其他链接器标志为-ObjC。

Answer 2

如果Wikitude引擎已启用，我会通过检查Query query = session.getNamedQuery("callStockStoreProcedure") .setParameter("stockCode", "7277"); List result = query.list(); for(int i=0; i<result.size(); i++){ Stock stock = (Stock)result.get(i); System.out.println(stock.getStockCode()); }通知来解决此问题。如果不是，我执行Wikitude的启动方法，一切正常。
