如何直接移动到在第三个选项卡iPhone中作为子视图添加的视图

Question

First of all sorry for the title.Actually i dont know how to give a appropriate title for this scenario.

I have a login view.Once the authentication is success next view is a tab bar view with four tabs.I created this as follows:

UIViewController *firstTab = [[SAHomeView_iPad alloc]initWithNibName:@"SAHomeview_iPad" bundle:nil];
         firstTab.tabBarItem.image = [UIImage imageNamed:@"Home.png"];
         UIViewController *secondTab = [[SAMenuView_iPad alloc]initWithNibName:@"SAMenuView_iPad" bundle:nil];
         secondTab.tabBarItem.image = [UIImage imageNamed:@"Menu.png"];
         UIViewController *thirdTab = [[SAGraphView_iPad alloc]initWithNibName:@"SAGraphView_iPad" bundle:nil];
         thirdTab.tabBarItem.image = [UIImage imageNamed:@"Graph.png"];
         UIViewController *fourthTab = [[SAAboutView_iPad alloc]initWithNibName:@"SAAboutView_iPad" bundle:nil];
         fourthTab.tabBarItem.image = [UIImage imageNamed:@"info.png"];
         UITabBarController *tabBarController = [[UITabBarController alloc] init];
         tabBarController.viewControllers = [NSArray arrayWithObjects:firstTab, secondTab,thirdTab,fourthTab, nil];
         SAAppDelegate *delegate = [UIApplication sharedApplication].delegate;
         delegate.window.rootViewController = tabBarController;

Now in the third tab,i have added a calendar button,which when pressed will give a calendar view.i added this calendar view as subview in third tab.

Now once the user is logged in,there will be a calendar button in the home tab. Once user tap the calendar button he should move to the calendar view. This calendar view is actually added as a subview in the third tab.

Can anyone please help me to solve this scenario. Many thanks in advance.

Answer 1

I suggest that you take the calendar view out of your thirdTab view hierarchy and assign it to it's own custom viewController, so that it can be presented with equal status from any other viewController in your app.

You can then invoke the calendar using a modal storyboard segue or in code using:

[self presentViewController:calendarViewController animation:YES completion:NIL];

and dismiss it:

[self.presentingViewController dismissModalViewControllerAnimated:YES];

When you present it, you will lose your tab controller context, as the expectation is that you will return to the view that presented it. When you dismiss it, you get that presenting view back with the tab bar context.

Friends finally i did it in this way.Thanks for all your help.Hope this help you also.:)

- (IBAction)moveToCalendar:(id)sender {
    self.tabBarController.delegate = self;
    self.tabBarController.selectedIndex = 2;
    [(SAGraphView_iPad *)self.tabBarController.selectedViewController calendar:self];
}
