NSWorkspace 為應(yīng)用程序提供如下服務(wù)：
1）打開，操作文件/設(shè)備，獲取文件/設(shè)備信息
2）跟蹤文件，設(shè)備以及數(shù)據(jù)庫的變動
3）設(shè)置或獲取文件的 Finder 信息
4）啟動應(yīng)用程序。
NSWorkspace 是個 Singleton 類，我們通過 sharedWorkspace 來訪問它。比如下面的語句用 TextEdit 打開指定的文件：
[[NSWorkspace sharedWorkspace] openFile:@"/Myfiles/README" withApplication:@"TextEdit"];
下面的代碼演示了大部分 workspace 的應(yīng)用，運(yùn)行效果圖如下：
- (IBAction) launchApplication:(id) sender
{
NSWorkspace?*?workspace?=?[NSWorkspace?sharedWorkspace];
//BOOL?wasLaunched?=?[workspace?launchApplication:@"Safari"];
//?launch?without?activation
//
BOOLwasLaunched?=?[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);
}
