Unwind Segues are not passed to the child view controller

[RVijay007]

I'm having an issue where my unwind segues are not passed to the child view controller of the Storyboard Link. The canPerformUnwindSegue method correctly detects whether the child view controller implements the desired unwind method, but the method is called on the StoryboardLink instead of the child view controller. I ended up adding forwarding invocation code to your class to get the messages passed to the correct controller.

- (BOOL)respondsToSelector:(SEL)aSelector {
    if ([super respondsToSelector:aSelector])
        return YES;
    else {
        return [self.scene respondsToSelector:aSelector];
    }
    return NO;
}

- (NSMethodSignature *)methodSignatureForSelector:(SEL)aSelector {
    NSMethodSignature* signature = [super methodSignatureForSelector:aSelector];
    if (!signature) {
        signature = [self.scene methodSignatureForSelector:aSelector];
    }
    return signature;
}

- (void)forwardInvocation:(NSInvocation *)anInvocation {
    if ([self.scene respondsToSelector:[anInvocation selector]])
        [anInvocation invokeWithTarget:self.scene];
    else
        [super forwardInvocation:anInvocation];
}

Thanks for including the code snippet. I also updated the LinkedStoryboards sample accordingly.

@rob-brown that's really a bad idea, -forwardInvocation cause so many bugs.detail see #68 #71
