Tab bar, reload every time tab is pressed

Question

I am creating an app in which I have five tabs. I need to reload each controller every time when tab is pressed.

Answer 1

 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
    {
    //other codes

    [self.tabBarController setDelegate:self]

    //other codes
    }

// UITabBarControllerDelegate method.
- (void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController
{
    if ([viewController respondsToSelector:@selector(reloadDataTemp)]) {
        [(YourViewController *)viewController reloadData];
    }
}
