UIScrollView resizing

Question

I'm very new in iOS development. Sorry for my English. I'm trying to make simple form, multi-view, universal app.But I have a serious problem with my scrollView. I'm adding my pages (4 count) via addSubview: method and everything is run good, but when I rotate device everything becomes to a completely mess. I think that I don't resize my ScrollView correctly. What is the best approach in my case? I'm using Xcode5 . This is the piece of code where I add my subViews.

-(void)scrollViewResize{
    scrollView.translatesAutoresizingMaskIntoConstraints = NO;
    [scrollView setContentOffset:CGPointMake(0, 0)animated:NO];
    [scrollView setContentSize:currentView1.frame.size];
    [scrollView addSubview:currentView1];
    [scrollView setScrollEnabled:YES];
}

-(void)viewDidLayoutSubviews{
  [super viewDidLayoutSubviews];
  [self.scrollView layoutIfNeeded];
  self.scrollView.contentSize = self.testView.frame.size;
 }

If I Run my app in portrait and then I rotate in Landscape it works fine for 1st subView.

As you stated that you're new to iOS programming then you should read some tutorials about Autoresize mask . Autoresize mask is good solution in your case.
