objective-c - UIApplication _preferredInterfaceOrientationGivenCurrentOrientation:SIGABRT

我的应用在启动时继续崩溃，并出现以下奇怪错误:-[UIApplication _preferredInterfaceOrientationGivenCurrentOrientation:]: unrecognized selector sent to instance 0x23b5f0。 _preferredInterfaceOrientationGivenCurrentOrientation方法被称为自动旋转逻辑，因此我删除了所有提及

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation

并清理了目标和构建文件夹，但它不断记录异常。有没有人遇到过这个奇怪的错误，有人修复过吗？

最佳答案

您的appDelegate中是否有这样的想法？

self.window.rootViewController = [UIApplication sharedApplication];

UIViewControllers之间的转换出现时，将在后台调用_preferredInterfaceOrientationGivenCurrentOrientation方法。实际上，您的UIApplication是消息接收者，意味着您已将其转换为应用程序中某个位置的视图控制器或类似的东西。
