Declaration
@interface NSWorkspace : NSObject
Overview
There is one shared NSWorkspace object per app. You use the class method shared to access it. For example, the following statement uses an NSWorkspace object to request that a file be opened in the TextEdit app:
[[NSWorkspace sharedWorkspace] openFile:@"/Myfiles/README" withApplication:@"TextEdit"];
You can use the workspace object to:
Open, manipulate, and get information about files and devices
Track changes to the file system, devices, and the user database
Get and set Finder information for files
Launch apps
Legacy Constants
Table 1 describes keys for an NSDictionary object containing information about an app. This dictionary is returned by active and launched, and is also provided in the user of NSWorkspace notifications for app launch and termination.
Note that these constants are considered legacy.
