Where can one view the result of a printf function call in xcode?

Where can one view the result of a printf function call in xcode? i.e. where is the console/outp开发者_开发问答ut window....

Cmd+Shift+R opens Console where you see your program's output (like NSLog(@"text %@", str)) and errors

View | Show Debug Area or click the middle icon in the view toolbar in the top right of the window.

1) I would use NSLog for this, not printf.

2) "When XCode runs your project, the editor changes to show a little black button with the letters "GDB" in it. Click on that to see the Debugger which has the console in it." from: How to show the Logged Messages window in Xcode
