[Cocoa] Nsworkspace Use Example

http://blog.csdn.net/kesalin/article/details/6749107

Nsworkspace provides the following services for applications:
1) Open, manipulate files/devices, get File/device information
2) Tracking of files, equipment and database changes
3) Set or get Finder information for the file
4) Start the application.

Nsworkspace is a Singleton class, and we access it through SharedWorkspace. For example, the following statement opens the specified file with TextEdit:
[[Nsworkspace SharedWorkspace] openfile:@ "/myfiles/readme" withapplication:@ "TextEdit"];

The following code demonstrates most of the workspace applications and runs as follows:

Here's the code, the code is simple:
