OS X App Sandboxing and arbitrary files access - Update to Document-based?

由 懵懂的女人 提交于 2020-01-04 06:31:29
问题 My OS X app (currently not sandboxed) accesses files contained inside a directory set by the user (one chooses the path with a NSOpenPanel and a reference to this path is kept throughout execution). The list of files is generated via NSDirectoryEnumerator and I then read from and write to those files using AVAsset and taglib (in C++ with a bridging header) respectively. As expected, enabling Sandboxing in Xcode rendered the app useless, the list of files given by NSDirectoryEnumerator is

问题 I have a document-based application. So I need an icon for my app as well as an icon for my documents. In Xcode/Images.xcassets there is an item called AppIcon which I can use for setting the icon of the app. But how do I make an icon for my documents?

问题 There's a file type my application import but not save. I've added an entry to the document types and set it to read-only, but that doesn't yield the import behaviour that I'm looking for. Instead, my app will just open the file and when I save the original file is overwritten in my own file format. How to set up my document or document types to make it so that a new document is created with the data from the original document, instead of the original being opened? 回答1: 1. Declare the file

Having Trouble Getting the UIDocumentBrowserController to open docs in a Document based app

由 半世苍凉 提交于 2019-12-05 00:24:05
问题 I've been working on a new Document-based app, and was super glad about the new UIDocumentBrowserController...trying to roll my own solution for the document browser UI was tricky! I'm having some trouble getting the browser to open documents after they've been created. What happens now is that when I choose to create a new document in the document browser, the document is created and opened as expected, although an error message is logged. However, after the doc is closed, I cannot reopen

Tutorial/example of a minimal document-based app

由 瘦欲@ 提交于 2019-12-04 00:57:57
问题 I'm trying to understand how the things in Cocoa works but I'm struggling with one thing. I saw http://cocoawithlove.com/2010/09/minimalist-cocoa-programming.html and http://casperbhansen.wordpress.com/2010/08/15/dev-tip-nibless-development/ and I think I somewhat understood. Now, I would like to do the same but for a "Document-based application". Please, does anyone know of a tutorial or example akin to the ones above? Alternatively, what do I need to do to make it work? I think I need to

What are the best uses of document stores?

由 馋奶兔 提交于 2019-12-03 04:50:39
问题 I have been hearing a lot about document oriented data stores like CouchDB. I understand the uses of BigTable like stores such as Cassandra. After reading this question, I was wondering what the conditions would be to merit using a document store? 回答1: Column-family stores such as Bigtable and Cassandra have very limited querying capabilities. The application is responsible for maintaining indexes in order to query a more complex data model. Document databases allow you to query the content,
