Downloading Data

In MainViewController.m we have two variables

@interface MainViewContoller : UITabBarController <CLLocationManagerDelegate>
    NSMutableArray *_dataArray;
    CLLocationManager* _locationManager;

_locationManager that is used to know user position and _dataArray that we load with PanoramioObject objects in PanoramioConnection method of the same MainViewController.m

 *Call the function that downloads the images.
    _dataArray=[Information PanoramioConnectionWithLocation];
    [self performSelectorOnMainThread:@selector(fetchedData) withObject:nil waitUntilDone:NO];

You can see how we use Panoramio API in the PanoramioConnectionWithLocation method of the Information class
