问题 I'm having issues trying to preview big files in my iPad app. In the app we use UIDocumentInteractionController. When we try to open big files (> 100 MB) the UIDocumentInteractionController only shows a grey screen with the name and size of the file.

问题 I stumbled upon this SO discussion on adding/removing qlpreviewcontroller's uibarbuttonitems. However they were removing the navigation bar and overlaying a new one on top of it. I was looking to change the toolbar primarily because the toolbar that comes with QLPreviewController is black and the rest of the toolbars in my application are white.
