MacOS sandboxed application: access files without NSOpenPanel

由 夙愿已清 提交于 2020-05-14 04:02:30
问题 In a sandboxed NSDocument-based application, any compatible document can be accessed using the NSOpenPanel, no matter where the document is saved. Without NSOpenPanel, the application can only access files in the sandbox container. As my application manages two types of subclassed NSdocument (Text as a reader/writer and Image as a reader only), I try to implement a separate "Open Recent" menu for images.

If sufficient kernel resources are leaked, your app loses its ability to add file-system locations to its sandbox, such as via Powerbox or security-scoped

问题 EDIT: Additional information added at the bottom I have a sandboxed, document based application that loads a user selected quicktime movie into an AVPlayer, and everything was working perfectly. Now I am upgrading the code so that it will use Security Scoped bookmarks to get the URL rather than just storing a URL string so that the persistent store will allow the movie to be loaded upon relaunch of the application. When the bookmark is created it is stored in a Data variable of a managed
