I am using the following code to set a badge from my App delegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
sleep(2);
// Set the tab bar controller as the window's root view controller and display.
self.window.rootViewController = self.tabBarController;
[self.window makeKeyAndVisible];
//Count the news pending and show the badge
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *path = [documentsDirectory stringByAppendingPathComponent:@"datatesting.plist"];
NSFileManager *nfm = [[NSFileManager alloc] init];
if([nfm fileExistsAtPath:path])
{
// if file exists, get its contents, add more entries
NSMutableArray *array = [[NSMutableArray alloc] initWithContentsOfFile:path];
//Get the number of badge you have to show
int num;
num = [array count];
NSString *numerodeexp = [NSString stringWithFormat:@"%d",[array count]];
[[[[[self tabBarController] tabBar] items] objectAtIndex:2] setBadgeValue:numerodeexp];
}
else {
[[[[[self tabBarController] tabBar] items] objectAtIndex:2] setBadgeValue:@"0"];
}
return YES;
}
I will like to update the Value from one of my view controller and I am not able to update it with this code :
[[[[[self tabBarController] tabBar] items] objectAtIndex:2] setBadgeValue:@"0"];
What is the best way to update the Badge value from an ViewController ?
