didReceiveRemoteNotification and Tab Bar App updating view controllers

[Conor.Higgins]

Hi I have a question which I would imagine should be pretty straight forward but I'm stumped.

I am working with remote push notifications in a tab bar application. Each tab in the application has a navigation controller, each of which has a series of view controllers that are pushed and popped in different instances.

I have a home view controller which is shown on the first tab (index 0), and when it appears I am calling and parsing xml from an external php file, using the viewDidAppear method. Based on the xml data that is returned, the view controller changes graphically including the position of a slider, and a series of labels and images. This all works perfectly when I am clicking through the app so most of the hard work is done as far as I can see.

Each time I send a push notification to the app I want it to basically perform a similar task as the viewdidappear method. It would be very handy if I could just simply call the viewdidappear method again from inside the app delegate once the remote notification is received by the app but I can't figure out how to do this. I've tried setting up a public method and copying and pasting in the code I use in the viewDidAppear method but I am getting warnings like this:

instance variable 'example' accessed in class method

Has anyone got a suggestion for this? I am quickly approaching a very close deadline so if someone can help it would be really appreciated.

Mikelsoft, I fixed this to an extent by using my app delegate to create a new instance of the viewcontroller I was trying to access and then calling the function I needed to access. This works fine for updating data and other things like that. What sort of method are you trying to call?

Hi Conor,
I want to update a tabbaritem.badgevalue of the tabbarcontroller with a method in the appdelegate. The error says: "instance variable 'tabBarItem1' accessed in class method"and "instance variable 'tabBarItem2' accessed in class method"
Appdelegate.h

@interface AppDelegate : NSObject <UIApplicationDelegate, UITabBarControllerDelegate> {
UIWindow *window;
UITabBarController *tabBarController;
UITabBarItem *tabBarItem1;
UITabBarItem *tabBarItem2;
}
@property (nonatomic, retain) IBOutlet UIWindow *window;
@property (nonatomic, retain) IBOutlet UITabBarController *tabBarController;
@property (nonatomic, retain) IBOutlet UITabBarItem *tabBarItem1;
@property (nonatomic, retain) IBOutlet UITabBarItem *tabBarItem2;
+ (void) updateBadgeValue;

Appdelegate.m

@synthesize tabBarController, tabBarItem1, tabBarItem2;

+ (void) updateBadgeValue
{
tabBarItem1.badgeValue = "Test1";
tabBarItem2.badgeValue = "Test2";
}

I try to call this from one of the two viewcontrollers by using:
[AppDelegate updateBadgeValue];

It looks like there is a problem with the +(void) !!??
Thanks for your help, Mikel
