I'm trying to populate a UITableview with an array of cells. I usually do this from the viewDidLoad method but this time I want to populate the array based on location. Below is the first line of my interface:
@interface RootViewController : UITableViewController
<UITableViewDelegate, UITableViewDataSource, CLLocationManagerDelegate> {
In the implementation file the viewDidLoad method looks like this:
- (void)viewDidLoad {
// for location
self.locationManager = [[CLLocationManager alloc] init];
[locationManager startUpdatingLocation];
locationManager.delegate = self;
locationManager.distanceFilter = kCLDistanceFilterNone;
locationManager.desiredAccuracy = kCLLocationAccuracyBest;
[super viewDidLoad];
}
I populate the array of cells in the didUpdateToLocation method:
self.title = @"Open Buildings";
NSMutableArray *buildingArray = [[NSMutableArray alloc] initWithObjects:building1,
self.controllers = array;
The title of the view updates when location is found but the array doesn't populate. The array did populate before when I had the above code in the viewdidupdate. I had to move it to the didupdatelocation method because the application won't have the location info when the view loads in the viewDidLoad method.
Your table view doesn't know you have new data. So, once you have the new data, you need to tell your table view to reload:
[myTableView reloadData];
