Why is UIApplication not working in my Mac App

Question

i am using openURL for my iphone apps, works perfectly, but now i want to use it on mac, normally, i use this code

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"http://google.com"]];

and it works perfectly in Xcode for iPhone app, but when doing a mac app, it gets me this error:

"UIApplication" undeclared (first use in this function)

So help anyone?

UI library is used only for iPhone, iPad and iPod touch device development.And NSApplication is only used for mac desktop development applications. Therefore you must have used NSApplication instead of UIApplication. — Tirth, Jan 11 '11 at 11:34

As others have said, UIApplication is part of UIKit, a Cocoa Touch framework for iOS. On the Mac, you have to use AppKit, a Cocoa framework for Mac OS X, which provides NSApplication.

That being said, if you want to open a URL you need to use NSWorkspace:

[[NSWorkspace sharedWorkspace] openURL:[NSURL URLWithString:@"http://google.com"]];

You can't use UIApplication. You need to use NSApplication instead.

wow so fast :D btw, where are the IBActions in interfacebuilder? i created them (appdelegate.h, then .m) – Cykey Jan 11 '11 at 11:29
Not sure I understand what you mean by asking where IBAction in InterfaceBuilder are. You just link IBAction with delegates on the inspector. – Pablo Santa Cruz Jan 11 '11 at 11:31
