Xcode 如何在iOS5中旋转视图？

我在应用程序中使用了

splitviewController

。应用程序的方向严格设置为横向。我已经在构建设置中正确地完成了它

当我在iOS 5.1或更高版本中运行我的应用程序时，它运行得很好。但当我在iOS 5或更低版本中运行应用程序时，应用程序的方向不会更改为横向。这是个大问题。有什么解决办法吗

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
  // Return YES for supported orientations
  return (interfaceOrientation == UIInterfaceOrientationPortrait);
}

简单。插入以下内容：

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
    return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);
}

你应该换新衣服

return (interfaceOrientation == UIInterfaceOrientationPortrait); 

声明

return ((interfaceOrientation == UIInterfaceOrientationLandscapeLeft) || (interfaceOrientation == UIInterfaceOrientationLandscapeRight));

在所有

viewControllers

中为

orientation

 - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
   // Return YES for supported orientations
   [super shouldAutorotateToInterfaceOrientation:interfaceOrientation];
   return UIInterfaceOrientationIsLandscape(interfaceOrientation);
 }

 - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
   // Return YES for supported orientations
   [super shouldAutorotateToInterfaceOrientation:interfaceOrientation];
   return UIInterfaceOrientationIsLandscape(interfaceOrientation);
 }

尝试返回（（interfaceOrientation==UIInterfaceOrientationAndscapeLeft）| |（interfaceOrientation==UIInterfaceOrientationAndscapeRight））尝试

返回（（interfaceOrientation==UIInterfaceOrientationAndscapeLeft）| |（interfaceOrientation==UIInterfaceOrientationAndscapeRight））
