如何在iPhone中为横向编码?

问题描述

我知道我可以更改支持的界面方向，但是如果我希望横向视图与纵向视图完全不同或略有不同，我该如何编写代码?

I understand that I can change what interface orientations are supported, but if I want the landscape view to be entirely different, or somewhat different than the portrait view, how do I code for it?

谢谢.

推荐答案

为每个方向使用专用的视图控制器是最简单的方法.

Using a dedicated view controller for each orientation is the easiest approach.

如果唯一的区别是表示形式，而不是控制器逻辑，那么您还可以尝试编码单个视图控制器，以根据方向在两个视图之间交换.

If the only difference is presentation, not controller logic, then you could also try coding a single view controller to swap between two views depending on orientation.

例如伪代码

UIView *landscapeView = ...;
UIView *portraitView = ...;

when orientationChanged
{
   if landscape then
      [portraitView setHidden:YES];
      [landscapeView setHidden:NO];
      self.view = landscapeView;
   else if portrait then
      [landscapeView setHidden:NO];
      [portraitView setHidden:YES];
      self.view = portraitView;


   [self.view setNeedsDisplay];
}
