Instance Method

launchApplication:

Launches the specified app.

Declaration

- (BOOL)launchApplication:(NSString *)appName;

Parameters

appName

The name of the app to open.

Return Value

YES if the app was successfully launched or was already running; otherwise, NO.

Discussion

The appName parameter need not be specified with a full path and, in the case of an app wrapper, may be specified with or without the .app extension, as described in Use of .app Extension.

Before this method begins, it posts an NSWorkspaceWillLaunchApplicationNotification to the NSWorkspace object’s notification center. When the operation is complete, it posts an NSWorkspaceDidLaunchApplicationNotification.

It is safe to call this method from any thread in your app in macOS 10.6 and later.
