Answer 1

在 self.view 中添加UIScrollView。

现在根据方向设置 yourScrollView 的框架，并根据它的内容大小。但是在纵向框架和内容大小将相等，因此不会滚动。

现在在横向中，框架和内容大小将不相等，因此会有滚动

注意：根据方向调整 UIlements 的名气

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {

  if(UIInterfaceOrientationIsLandscape(interfaceOrientation))
  {
     [yourScrollView setFrame:CGRectMake(0,0,320,460)];
     [yourScrollView setContentSize:CGSizeMake(320,460)];
     //change frame of UIELement(labels) here according to orientation
  }
  else
  {
     [yourScrollView setFrame:CGRectMake(0,0,480,300)];
     [yourScrollView setContentSize:CGSizeMake(480,460)];
     //change frame of UIELement(labels) here according to orientation
  }
  return YES;
}
