tabBarView コントローラと TableViewController があります。行をクリックすると、マップ付きの UIViewController である別のタブに移動したい:
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
if(storeName)
[self setMap];
}
- (void) setMap {
NSLog(@"Name:%@\n", storeName);
NSLog(@"Adress:%@\n", storeAddress);
self.indexMapView.delegate = self;
self.indexMapView.showsUserLocation = NO;
self.locationManager = [[CLLocationManager alloc] init];
[locationManager setDelegate:self];
[locationManager setDistanceFilter:kCLDistanceFilterNone];
[locationManager setDesiredAccuracy:kCLLocationAccuracyBest];
[self.indexMapView setShowsUserLocation:YES];
CLLocationCoordinate2D location = [self getLocationFromAddressString:self.storeAddress];
NSLog(@"%g", location.latitude);
MapViewAnnotation *mapAnnotation = [[MapViewAnnotation alloc] initWithTitle:@"Store location" coordinate:location];
[self.indexMapView addAnnotation:mapAnnotation];
}
-(CLLocationCoordinate2D) getLocationFromAddressString:(NSString*) addressStr {
NSLog(@"FFF");
NSString *urlStr = [NSString stringWithFormat:@"http://maps.google.com/maps/geo?q=%@&output=csv",
[addressStr stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
NSError *error = nil;
NSString *locationStr = [NSString stringWithContentsOfURL:[NSURL URLWithString:urlStr] encoding:NSUTF8StringEncoding error:&error];
NSArray *items = [locationStr componentsSeparatedByString:@","];
double lat = 0.0;
double lon = 0.0;
if([items count] >= 4 && [[items objectAtIndex:0] isEqualToString:@"200"]) {
lat = [[items objectAtIndex:2] doubleValue];
lon = [[items objectAtIndex:3] doubleValue];
}
else {
NSLog(@"Address, %@ not found: Error %@",addressStr, [items objectAtIndex:0]);
}
CLLocationCoordinate2D location;
location.latitude = lat;
location.longitude = lon;
return location;
}
これは、MapViewController に移動する方法です。
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
MapViewController *mapViewController = [[MapViewController alloc]init];
[mapViewController setStoreAddress:store.address];
[mapViewController setStoreName:store.name];
[mapViewController viewDidLoad];
[self.tabBarController setSelectedIndex:4];
}
問題は、ページに再度アクセスしてもマップが更新されないことです。で試してみたところPushSegue
、うまくいきました。しかし、どうすればTabBarで動作させることができますか?
