I have a project in which I'm switching one view with another:

```
- (IBAction)onClick:(id)sender
{
ViewControllerSecond * sc=[[ViewControllerSecond alloc]initWithNibName:@"ViewControllerSecond" bundle:nil];
[UIView transitionFromView:self.view toView:sc.view duration:3.0
                   options:UIViewAnimationOptionTransitionFlipFromLeft completion:^(BOOL finished) {

}];
}

```

I'm using 3 seconds here to make a point. in this second view I have a method to update the GUI that adds another view from a view controller:

```
    -(void)updateGUI
{

    sample=[[ViewControllerSample alloc]initWithNibName:@"ViewControllerSample" bundle:nil];
    sample.view.frame=CGRectOffset(sample.view.frame, 0, 150);
    [self.view addSubview:sample.view];
}

```

Now, here is the problem: when I'm calling this from the viewDidLoad function - it's working just fine.
However, if called from the viewWillAppear function, the view will appear at the top of the screen and only after the animation has ended will jump to it's position.
How can it be fixed?
