iOS处理Orientation
Jake Lin · 2013-01-03 · via 博客园 - Jake Lin

在iOS6以后Orientation可以在plist文件里面进行设置。设置项是“Supported interface orientations”。

如果在iOS5或者一下版本UIViewController类默认支持Portrait only,要支持其他Orientation,需要重写 shouldAutorotateToInterfaceOrientation:方法。

- (BOOL) shouldAutorotateToInterfaceOrientation: (UIInterfaceOrientation) orientation

{

  return UIInterfaceOrientationIsPortrait(orientation); // only support portrait

  return YES; // support all orientations

  return (orientation != UIInterfaceOrientationPortraitUpsideDown); // anyting but

}
