Using presentViewController from UIView

Only UIViewController can present another view controller, so if you need to show a viewcontroller from view there are several way, one of them is like this:

make a viewcontroller on which your parent view is situated a delegate of it

ParentView *view = [ParentView new];
...
view.delegate = self;

then, inside ParentView call method of that delegate

- (IBAction)homeButtonPressed:(id)sender {
    [self.delegate buttonPressed];
}

and then, inside your VC implement

 -(void)buttonPressed {
    UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
    ViewController *vc = [storyboard instantiateViewControllerWithIdentifier:@"ViewController"];
    [vc setModalPresentationStyle:UIModalPresentationFullScreen];
    [self presentViewController:vc animated:NO completion:NULL];
}

If you need to keep this code inside UIView and avoid delegation you can do a trick like this (personally i don't like it but it should work)

-(void)buttonPressed{
    UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
    ViewController *vc = [storyboard      instantiateViewControllerWithIdentifier:@"ViewController"];
    [vc setModalPresentationStyle:UIModalPresentationFullScreen];
    [(UIViewController*)self.nextResonder presentViewController:vc animated:NO completion:NULL];
}

You can do this without using the delegate pattern. Here you go

ObjectiveC

UIViewController *currentTopVC = [self currentTopViewController];
currentTopVC.presentViewController......... 

- (UIViewController *)currentTopViewController {
    UIViewController *topVC = [[[[UIApplication sharedApplication] delegate] window] rootViewController];
    while (topVC.presentedViewController) {
        topVC = topVC.presentedViewController;
    }
    return topVC;
}

Swift

var topVC = UIApplication.sharedApplication().keyWindow?.rootViewController
while((topVC!.presentedViewController) != nil) {
     topVC = topVC!.presentedViewController
}
topVC?.presentViewController........
