To show A FirstViewController On Call of a method from SecondViewController in Iphone

Question

Actually I am Making an Alarm app. In that When i set the Time The UILocalNotification event happens at that time and it calls the method of AppDelegate class i.e didReceiveNotifications method. In this method i have written a code to call a method of SetViewController (showReminder method) and now in this method i want that it should show a NewViewController i.e TimeViewController as i have to show animation when the Alarm Invokes.

I need this as When Alarm invokes i have setted a Action sheet to appear but i wanted to show animation also.Action sheet appears in all views But the animation can be Shown in only particular view, that's why i need to show A different ViewController.

Here is the code for what i am trying :- I have tried al these also like PresentModalViewController, dismissModalViewController, AddSubview, remove superView... but result are negative :( what should i do..?

Almost Whole CODE:--

AppDelegate Class :-

- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification {
    if (notification){
        NSLog(@"In did Notification");
        NSString *reminderText = [notification.userInfo objectForKey:kRemindMeNotificationDataKey];
        [viewController showReminder:reminderText];
        application.applicationIconBadgeNumber = 0;
    }
}

setViewController.h :-

@interface SetAlarmViewController : UIViewController <UITableViewDataSource,UITableViewDelegate,UITextFieldDelegate,UIActionSheetDelegate>{

    IBOutlet UITableView *tableview;
    IBOutlet UIDatePicker *datePicker;
    IBOutlet UITextField *eventText;
    TPKeyboardAvoidingScrollView *scrollView;

    IBOutlet UINavigationBar *titleBar;
    IBOutlet UIButton *setAlarmButton;
    AVAudioPlayer *player;
    int index;
    The420DudeAppDelegate *appDelegate;
    TimeViewController *viewController;

   IBOutlet UIImageView *animatedImages;

    NSMutableArray *imageArray;
    AVPlayerItem *player1,*player3;
    AVPlayerItem *player2,*player4;
    AVQueuePlayer *queuePlayer;
}

@property(nonatomic) UIReturnKeyType returnKeyType;

Answer 1

Your viewController is probably showing the view, but without the SetViewController's view on the screen you can't see it. Your going to have to first go to the SetViewController and then present your TimeViewController. Is this right, you want to show the SetViewController but call the showReminder: method right away? But only from the didReceiveLocalNotification:.

If this is the case, set a flag,and a text property in your SetViewControllers .h,

BOOL isFromNotification;
NSString *notifText; 

and present the SetViewController,and set the flag

SetViewController *setViewController = [SetViewController alloc]........
setViewController.isFromNotification = YES;
setViewController.notifText = reminderText;
[self presentModalViewController animated:YES}

and then in the viewDidAppear: of SetViewController

if(isFromNotification = YES){
  [self showReminders:notifText];
}

Answer 2

If I got you right ,

upon notification you would like to show animation on a new view and then show the action sheet ?

Right now you call from appdelegate

[viewController showReminder:reminderText];

which by the way should be self.viewcontroller or _viewcontroller for the actually retained object

In showreminder you call

animation, which in itself adds a subview and by the way is running in the same thread , ie in serial. and then you add the viewcontroller again as a subview. and then you try to add the actionsheet from parent to the subview(viewcontroller), when actionsheet should probably be in the viewcontroller itself.

Did i get that right ?

No sure really whats breaking down, could be on several areas, as pointed out above.

I would : make sure you call the retained objects through valid pointers ( using self for instance) have a viewcontroller that you present modal as a subview that show animations on a separate thread (performselectoronthread) and have the actionsheet on that. Then if you need to call the parent, you setup a delegate or you do the ugly way.

self.yourviewcontroller.myParentObj = self

ie set a yourviewcontroller pointer on the sub viewcontroller, which you can then openly call like

[self.myParentObj whatevermethod_you_have_in_parent];

But then again I write this from top of my head..
