问题 I have files of a format that has no declared UTI, so Launch Services has assigned to it a dynamic UTI ( dyn.ah62d4rv4ge81g23wsmw1a5dbte ). I have no control over the UTI of these documents. It also happens that I would like to develop a Quick Look generator for that format, and that Quick Look generators only rely on the document UTI, and will ignore any other kind of document identification present in their property list (such as the creator code and the extension). Is it safe for me to use

问题 I'm trying to write a simple Quick Look Preview Extension for my UIDocument-based iOS app. The problem is that in my implementation of preparePreviewOfFile(at:completionHandler:) my attempt to open the UIDocument based on the URL I'm being handed is failing. I instantiate my document with the file URL and call open(completionHandler:) but I'm not getting any data, and I'm seeing a console message that the file coordinator has crashed. All of this works fine in my actual app; it's just the

问题 This was working perfectly - before I upgraded to Xcode 10 that is. My app has a Quicklook and a Spotlight plugin integrated into it. These plugins are built separately and then, in the Build Phase, copied (two Copy Files) with the following settings: Destination: Wrapper Subpath: Contents/Library/<QuickLook|Spotlight> Code Sign on Copy Now, when I attempt to Archive in order to submit my App to the Mac App Store, my application archive to 'Other Items' instead of 'MacOS Apps'. If I remove my

问题 I have created an iOS Quick Look Preview Extension which gets called by iOS whenever the user does a Spotlight search and previews a result from my app. The preview loads fine, but when I try to access a cloud file from within the extension it fails with DNS error, saying Operation not permitted . I have found that on MacOS I need to disable sandboxing or, if using sandbox, give permission for network access, but this is iOS. There are no such settings here. How can I make it work? Here is my

问题 I've been following the brilliant instructions in this answer, which work perfectly. However, my file type is mime "application/notforquicklook" and quicklook still tries to open it. This causes general gear spinning and nothing happening. How can I get around this problem? My files are compressed plists. Before I was using full XML plists, which worked fine, but they are too big (with no advantage). Is this a question of choosing the right MIME type, or something else? 回答1: in fact, you
