可可应用;在预览中打开文件（pdf）

Question

I have a file path to a pdf and I want it to open in Preview. Also, I want finder to launch highlighting the file.

On iOS I would do:

UIApplication app = [UIApplication sharedApplication];
[app openURL:url];

But I have no idea what's the alternative in Cocoa app. Thanks

You should look at NSWorkspace

           NSString* path = [[NSString alloc] initWithBytes:installerPath.str() length:installerPath.dataLength() encoding:NSUTF16LittleEndianStringEncoding];
             [[NSWorkspace sharedWorkspace] openFile:path];
             [path release];
