[[NSWorkspace sharedWorkspace] openFile:@"/Myfiles/README" withApplication:@"TextEdit"];
下面的代码演示了大部分 workspace 的应用，运行效果图如下：
- (IBAction) launchApplication:(id) sender
{
NSWorkspace * workspace = [NSWorkspace sharedWorkspace];
//BOOL wasLaunched = [workspace launchApplication:@"Safari"];
// launch without activation
//
BOOL wasLaunched = [workspace launchAppWithBundleIdentifier: @"com.apple.Safari"
options: NSWorkspaceLaunchWithoutActivation
additionalEventParamDescriptor: NULL
launchIdentifier: nil];
if ( wasLaunched )
NSLog (@"Safari was launched");
else
NSLog (@"Safari was not launched");
NSArray * apps = [workspace valueForKeyPath:@"launchedApplications.NSApplicationName"];
self.launchedApplications = [NSString stringWithFormat:@"Launched Applications:\n%@", apps];
NSLog(@"Launched Applications:\n%@", apps);
