NSWorkspace does this kind of stuff the documentation has near the top the example code

[[NSWorkspace sharedWorkspace] openFile:@"/Myfiles/README"
                        withApplication:@"TextEdit"];

You can invoke, openURL to open the default PDF viewer

[NSWorkspace sharedWorkspace] openFile: pdfFilePath];

and if you want to launch the application you can invoke

[[NSWorkspace sharedWorkspace] launchApplication:appPath];

Want to open PDF within your application then I recommend you to read PDFKit: Apple PDFKit Doc
