Why portrait content displayed inside the landscape orientation?

Question

For a view controller, I am using the following code to restrict the orientation to landscape.

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

However, the display result is not correct

It shows the portrait content inside the landscape window.

what will be the possible cause?

从info.plist中删除不需要的方向，或者只是在ios中通过“自动布局”
