Reload if a setting is changed in the settings app while in background

[malhal]

If the in app settings controller is visible, if you leave the app and go to the Settings app and change a setting, when you come back to the app the settings controller still has the old values. Fix with these changes:

• (void)viewWillAppear:(BOOL)animated { ... [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(applicationWillEnterForeground:) name:UIApplicationWillEnterForegroundNotification object:nil]; }
• (void)viewWillDisappear:(BOOL)animated{ ... [[NSNotificationCenter defaultCenter] removeObserver:self name:UIApplicationWillEnterForegroundNotification object:nil]; } -(void)applicationWillEnterForeground:(NSNotification*)notify{ // reload in settings in case they were changed in the prefs app. [[NSUserDefaults standardUserDefaults] synchronize]; // show any changes if they happened in the background. [self.tableView reloadData]; }
