iphone – iOS – QLPreviewController – 如何阻止QuickLook旋转？

概述我有QuickLook(QLPreviewController)几乎按照我想要的方式工作,但由于图像特征,我不希望它旋转成纵向.我在“shouldAutoRotateToInterfaceOrientation”方法中配置它只返回yes用于横向旋转(参见下面的代码详细信息)但它仍然旋转到肖像. 注意：shouldAutoRotateToInterfaceOrientation是一个直接副本,在我的 我有QuickLook(QLPrevIEwController)几乎按照我想要的方式工作,但由于图像特征,我不希望它旋转成纵向.我在“shouldautoRotatetoInterfaceOrIEntation”方法中配置它只返回yes用于横向旋转(参见下面的代码详细信息)但它仍然旋转到肖像.

注意：shouldautoRotatetoInterfaceOrIEntation是一个直接副本,在我的所有视图控制器中用于此项目,它在其他视图控制器中工作.

解决方法 在AppDelegate.m中替换

return UIInterfaceOrIEntationMaskAll;

同

return UIInterfaceOrIEntationMaskLandscape;

像这样：

- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrIEntationsForWindow:(UIWindow *)window{    return UIInterfaceOrIEntationMaskLandscape;}
