Question

I have a method called getCurrentCycle in one of my viewControllers that I use in a tab based application. I would like to call this method from the applicationDidBecomeActive app delegate method.

Can someone help me out with this?

Check out the NSNotification Class Reference.

In the controller that has the getCurrentCycle method, add the following:

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(getCurrentCycle:) name:@"getCurrentCycle" object:nil];

When you want to call getCurrentCycle, add this:

[[NSNotificationCenter defaultCenter] postNotificationName:@"getCurrentCycle" object:nil];

Also, you will need to change your getCurrentCycle to:

- (void)getCurrentCycle:(NSNotification *)notification
