launch-services

Does anyone know of a good way to find (in the filesystem) every app with a given bundle identifier? NSWorkspace and Launch Services let you look for an app by bundle identifier, but only return a single result. I suspect Spotlight ( NSMetadataQuery ) might help, but I'm a bit unclear on its API, so I'm not sure if there's an appropriate key. There's the command-line lsregister tool (inside LaunchServices.framework), which can be told to (re)register everything on the system and then dump a report on everything it knows about. Relying on that seems less than ideal, since it's undocumented and

I have the list of the applications for given file extension (using LSCopyApplicationURLsForURL). I want to change the default file association from code upon selecting one of the applications from the above call. Is there a way to do this? Here is a snippet of code for a very related task: set yourself as the default application for a given file extension: #import <ApplicationServices/ApplicationServices.h> #import "LaunchServicesWrapper.h" @implementation LaunchServicesWrapper + (NSString *) UTIforFileExtension:(NSString *) extension { NSString * UTIString = (NSString *

Basic problem I'm looking for a solution to enumerate all applications installed on a (Mac) OS X system, i.e. all application bundles registered with LaunchServices . Simple approach that did not work (Please note: lsregister can be found under /System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister ). Currently I am using the output of lsregister -dump | grep -E '^.*[ \\t]*path:[ \\t]+(\/.*)$' | grep -Eo '\/.*' , which has a few problems: .app bundles with newlines ( \n , which is valid on UNIX) are not handled correctly (This issue would be

I am trying to implement the registering process that allows my iOS app to show up in the "Open in" list of other applications (as described in Apple's Document Interaction Programming Topics ). I want my app to be able to handle audio from any app that will provide a standard audio file format (MP3, AIFF, WAV, etc.). As I understand it, all I should need to do is add the CFBundleDocumentTypes key, with relevant subdata, to my app's Info.plist. This is what I put in (via Xcode 4's Document Types editor): <key>CFBundleDocumentTypes</key> <array> <dict> <key>CFBundleTypeIconFiles</key> <array>
