close uitableview and reload another uitableview - tableview

Question

i have problem.
I have CityViewController.m
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"MainStoryboard" bundle:nil];
TheatreController *tmpTheatreController = [storyboard instantiateViewControllerWithIdentifier:#"TheatreController"];
NSString *cityView = [[self.arrayCity objectAtIndex:indexPath.row] valueForKey:#"idCity"];
tmpTheatreController.cityView = cityView;
//[self.navigationController pushViewController:tmpTheatreController animated:YES];
[tmpTheatreController.tableView reloadData];
[self.delegate citiesViewControllerCancel:self];
}
When i select the city pass correctly the "idCity" in TheatreController.m
...
-(void) prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if([segue.identifier isEqualToString:#"SelectCity"])
{
UINavigationController *nc = segue.destinationViewController;
CityViewController *mvc = [[nc viewControllers] objectAtIndex:0];
mvc.delegate = self;
}
}
...
- (void)viewDidLoad
{
[super viewDidLoad];
NSString *webUrl = #"http://localhost:3000/theatres?city=";
webUrl = [webUrl stringByAppendingFormat:#"%#", cityView];
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
NSData* data = [NSData dataWithContentsOfURL:[NSURL URLWithString:webUrl]];
[self performSelectorOnMainThread:#selector(fetchedData:)
withObject:data waitUntilDone:YES]; });
}
- (void)fetchedData:(NSData *)responseData {
NSArray* json = [NSJSONSerialization
JSONObjectWithData:responseData
options:kNilOptions error:nil];
NSMutableArray *theatreTMP = [[NSMutableArray alloc] initWithCapacity:[json count]];
int i = 0;
for (id object in [json valueForKeyPath:#"response.name"]) {
Theatres *t = [[Theatres alloc] init];
NSLog(#"JSON: %#", [[json valueForKeyPath:#"response.name"] objectAtIndex:i]);
t.theatre = [[json valueForKeyPath:#"response.name"] objectAtIndex:i];
t.idTheatre = [[json valueForKeyPath:#"response.id"] objectAtIndex:i];
[theatreTMP addObject:t];
i++;
}
self.arrayTheatre = [theatreTMP copy];
[self.tableView reloadData];
}
I have correctly the response of the server and all parameter are correct, but the problem i have with reloadData of the tableView main![enter image description here][1]. I dont see the update table.
HELP ME thanks

Answer 1

i have resolved with this solution
In the CityViewController.m
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
NSString *cityView = [[self.arrayCity objectAtIndex:indexPath.row] valueForKey:#"idCity"];
[self.delegate performSelector:#selector(reloadTable:) withObject:cityView];
[self.delegate citiesViewControllerCancel:self];
}
and in the TheatreTableView.m
- (void) callServer:(NSString *)idCity {
NSString *webUrl = #"http://localhost:3000/theatres?city=";
webUrl = [webUrl stringByAppendingFormat:#"%#", idCity];
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
NSData *data = [NSData dataWithContentsOfURL:[NSURL URLWithString:webUrl]];
[self performSelectorOnMainThread:#selector(fetchedData:) withObject:data waitUntilDone:YES];});
}
....
- (void) reloadTable:(id)idCity
{
[self callServer:idCity];
}
Thanks
