Question

I created my application settings in Settings.bundle. I go into the Settings App and update a value. When I relaunch my app (which was in the background), how do I check for the updated settings in the Settings App.

I tried the following but I still get the old value. Any suggestions?

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

- (void)checkAutoUpdateSettingsForNotificaiton:(NSNotification *)aNotification
{
    NSNumber *period = [[[NSUserDefaults standardUserDefaults] objectForKey:@"periodID"] retain];

}

Answer 1

I had to add [[NSUserDefaults standardUserDefaults] synchronize]; to do the synchronization.
