问题 I need to get the same kind of info that you can get on "Get Info" when using Finder; more specifically I need the same info that is present in the "More Info" section, like Duration, Bitrate, Dimension, Codecs, Audio channels, etc. To get the basic info like size, type, I have: // Getting the file's attributes NSError *error; NSFileManager *fm = [NSFileManager defaultManager]; NSDictionary *fileInfo = [fm attributesOfItemAtPath:fileName error:&error]; Is there any native Cocoa library to get

问题 UPDATE: I found an answer though there may still be a better way - see the answer added below. a spotlight importer imports metadata that is an array of dates in which an item was accessed. Looks like this: kMDItemAccessedDates = ( "2012-06-18 07:00:00 +0000", "2013-01-10 08:00:00 +0000", "2013-01-15 08:00:00 +0000" ) I'd like to query for any of these files that were accessed on a particular date the user enters but I'm not finding the right syntax to do this. Wondering if it's possible to

问题 I am trying to use the output from mdfind to create a bunch of symlinks. Output of mdfind is like this: /pathtofile1/ /pathtofile2/ /pathtofile3/ So, I used sed to add ln -s to the start of each line, and awk {print $0 "/directory where I want this/"} ; after my single-line script successfully outputs this: ln -s "/pathtofile1/" "/directory where I want this" ln -s "/pathtofile2/" "/directory where I want this" ln -s "/pathtofile3/" "/directory where I want this" Problem is, when I run this,

问题 Since iOS9, it's possible to make Spotlight to show some items from own Application in search results. When user taps on result - App opens with some action handler. My question: is it possible somehow to get the full text of user's search request in application? Example: My application indexes item 'banana' using CoreSpotlight API. User searches: " banana pie ". Spotlight shows result from my App, actually, item " banana ". I would like to get string " banana pie ". I have already tried to

问题 I'm writing a swift program, and I want to list all metadata of a given folder using swift. As I understand, I'll need NSMetadataItem . The reference doc of NSMetadataItem is not very clear to me though, so I'm unable to write a code sample here. How to list all metadata of a folder? 回答1: Initialize a new instance of NSMetadataItem with the folder's NSURL: let item = NSMetadataItem(URL: folderURL) Then safely unwrap the values: if let item = item, attributes = item.valuesForAttributes(item

问题 I'm new to Swift programming, Recently I have implemented spotlight search for my app with Swift. Everything is working well and good however I"m getting few crash reports nowadays and I have no clue what is "Partial apply" and why it is crashing.

问题 Related to: Query Windows Search from Java But this time to use OSX's spotlight I would like to consume OSX spotlight service from Java. Is there an API available? . 回答1: There is no Java API for Spotlight that I am aware of (I don't think it was added to the now deprecated Cocoa-Java bridge development on the bridge was stopped). There is a procedural C API for Spotlight, however, that you could wrap with JNI. 回答2: I found some code that wraps the mdfind command line, works fine for me:

问题 I found the command "mdls" which will show the metadata but I can't see how to delete it. I want to get rid of the comments "kMDItemFinderComment", "kMDItemWhereFroms" from my files. Is there a way to do this? 回答1: I think you're looking for the xattr command, available in Terminal: xattr -pr com.apple.metadata:kMDItemFinderComment / that will print all the finder comments for all files on your boot volume. To delete, use the -d switch: xattr -dr com.apple.metadata:kMDItemFinderComment / You

问题 At the moment I have spotlight-api code which searches email's body. I'm using NSMetadataQuery and creating predicate for "kMDItemTextContent like[c] %@" . This works fine when requested "search-term" is in body of email. In Spotlight App (magnifier icon in top right) if I enter "to: john" I'll get list of emails in which "to" field contains word "john" (e.g. part of some email address john@something.com). I tried to achieve this with [NSCompoundPredicate orPredicateWithSubpredicates:] by

问题 The name of my app is French Translator + This app name is too long to be displayed under the app icon so I would like to shorten it to Translator +, however I would still like users to find it when searching Spotlight for "french". How can I register an app name for Spotlight searches that is different than app name appearing under the app icon. 回答1: You can always add your own keywords to the search index. Something like this: let attributeSet = CSSearchableItemAttributeSet(itemContentType:
