I'm trying to update the interface contents of a ContainerView on iOS (UIViewController embedded in a UIView) from the UIViewController that it's being displayed in. However, the ContainerView just won't update its content.
The ContainerView and the ViewController are associated with different classes. I can pass data between the two View Controllers by using a few methods like these:
- (void)displayStringInContainer:(NSString *)string
The string gets successfully passed to the ContainerView from the ViewController, however when I try to display that string in an interface element - nothing happens (even though the code is getting called):
self.buttonName.titleLabel.text = string;
I've even tried calling setNeedsDisplay on the button, but nothing happens. Note that this is happening with all interface items.
Here's how I call the method on the ContainerView from my ViewController:
ContainerViewController *cvc = [[ContainerViewController alloc] init];
[cvc displayStringInContainer:@"Text"];
I've done quite a bit of searching, but haven't found anything (also tried to look on the Apple Dev Site, but it's been down for the past three days :P). Does anyone know how to update the content of a ContainerViewController from another ViewController? Why isn't this working? I've been scratching my head on this for a while now.
