Question

Am getting the device local currency symbol by using this code.

 NSLocale *theLocale = [NSLocale currentLocale];
 NSString *symbol = [theLocale objectForKey:NSLocaleCurrencySymbol];
 NSLog(@"Symbol : %@",symbol);
 NSString *code = [theLocale objectForKey:NSLocaleCurrencyCode];
 NSLog(@"Code : %@",code);

When the app restart the currency symbol changing but when the app from background the currency symbol not updating.

1. In iPhone setting i have changed the region United States and launched the app the currency symbol show “$”.
2. When i have change the region India and get the app from Background and call the same code it shows again “$”. The currency symbol not updating. When i came back and reenter into the screen the currency symbol updating to India symbol.

In appDelegate:

- (void)applicationWillEnterForeground:(UIApplication *)application:

[[NSNotificationCenter defaultCenter] postNotificationName:@"CurrencyUpdated" object:nil];

In sampleViewController: viewDidLoad

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(reloadCurrencySymbol) name:@"CurrencyUpdated" object:nil];

In sampleViewController:

-(void) reloadCurrencySymbol
{
    NSLocale *theLocale = [NSLocale currentLocale];
    NSString *symbol = [theLocale objectForKey:NSLocaleCurrencySymbol];
    NSLog(@"Symbol : %@",symbol);
    NSString *code = [theLocale objectForKey:NSLocaleCurrencyCode];
    NSLog(@"Code : %@",code);
}

Can anyone please help to solve this issue? Thanks in advance.

EDIT

I have recalled the [self viewDidLoad]; but the region has not changed. When i return to previous screen and again enter into the same screen the region is updating. Can anyone please help to solve this? Thanks.

Answer 1

in your sampleview controller add this in viewdidLoad

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(reloadCurrencySymbol) name: UIApplicationDidBecomeActiveNotification object:nil];

this is the right way to reload your symbol when the app becomes active
