I am creating an app in which I have five tabs. I need to reload each controller every time when tab is pressed.
Put the code you want to reload, in the view will appear or in view did appear of all the view.
All the best.
Example:
// AppDelegate ( and <UITabBarControllerDelegate> )
// Creation tabbar and controllers
UIViewController* myController1 = [[UIViewController alloc] init] autorelease];
UINavigationController* nav1 = [[[UINavigationController alloc] initWithRootViewController:myController1] autorelease];
UIViewController* myController2 = [[UIViewController alloc] init] autorelease];
UINavigationController* nav2 = [[[UINavigationController alloc] initWithRootViewController:myController2] autorelease];
NSArray *array = [NSArray arrayWithObjects: myController1, myController2, nil];
UITabBarController* tab = [[[UITabBarController alloc] init] autorelease];
tab.viewControllers = array;
tab.delegate = self; // <-- don't forget set delegate for TabBarController
// TabBarController Delegate methods
- (void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController;
{
// Reload selected VC's view
[viewController.view setNeedsDisplay];
}
- (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];
}
}
