With reference to my question asked Change Tab view after certain time interval received as response from Server request, I used following code to show the session timeout message when application comes to active state
Method in AppDelegate.m:
- (void)applicationDidBecomeActive:(UIApplication *)application
{
// to check the session
XTabViewController *XTabViewCon = [[XTabViewController alloc] init];
[XTabViewCon pushViewUponCheckedSession];
[XTabViewCon release];
}
Methods from XTabViewController.m
- (void)pushViewUponCheckedSession {
//THIS IS VERY IMPORTANT. IT CHECKS FOR SESSION
if ([[[ApplicationContext alloc] dataManager ] checkSession]) {
[self showSessionAliveView];
//here I can write something that will push a view that was seen last before leaving app to inactive state. May be NSNotification could help me
}
else {
[self showSessionTimeOutView];
}
}
- (void)showSessionTimeOutView {
//show activity indi
waitingIndicator = [[MyWaitingIndicator alloc]init];
[self.view addSubview:waitingIndicator];
[waitingIndicator setHidden:YES];
[waitingIndicator stopAnimating];
//push session timeout view
SessionTimeOutViewController *sessionTimeOutView = [[SessionTimeOutViewController alloc] init];
[[self navigationController] pushViewController:sessionTimeOutView animated:NO];
[sessionTimeOutView release];
[waitingIndicator release];
}
- (void)showSessionAliveView {
SessionAliveView *sessionAliveViewList = [[SessionAliveView alloc] init];
[[self navigationController] pushViewController:sessionAliveViewList animated:YES];
[sessionAliveViewList release];
}
My question is:
It(pushViewUponCheckedSession) works fine when I used it while switching between Tabs to check if session is expired.
- (void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController {
//if X Tab is selected then & only then call this method
if (tabBarController.selectedIndex == 2) {
[XTabViewCon pushViewUponCheckedSession];
}
}
But it fails to show the SessionTimeOutViewController's view upon checkedSession When App comes to active state, Do I need to do something like flushing the previous views. And then populate appropriate view by checking the session.
Thanks in advance
