技巧

1. 启动应用程序
system("open /Applications/Safari.app");
The "open" command works as if you double-clicked the file.

system("/Applications/Safari.app/Contents/MacOS/Safari");

You would get a new instance of Safari. Much like opening multiple instances of IE in Windows. But this isn't Mac behavior. so use "open" instead.

2. help
If it's a help file, don't forget that OS X provides a standard framework for dealing with those. Otherwise, you could use something like the following, which will open a resource file using the default application for that file type:
  Code:
NSString *path = [[NSBundle mainBundle] pathForResource: @"yourfile" ofType: @"html"];
BOOL success = [[NSWorkspace sharedWorkspace] openFile: path];
