Is this icon included as part of the Cocoa API? What is the icon name?
I read the HIG but could not find a reference - https://developer.apple.com/library/mac/documentation/UserExperience/Conceptual/OSXHIGuidelines/SystemProvided.html#//apple_ref/doc/uid/20000957-CH92-SW1
It's undocumented. The image's name is NSImageNameSidebarTemplate. (NSSidebarTemplate in IB, though it's only visible at runtime).
I don't know though if this is off-limits and whether it will get you rejected.
Can't see anything that would match in the constants specified in
NSImage - i.e. it's not any of the images listed in Image Template Constants, View Type Template Images, etc. -
so I doubt it's generally available to apps..

What should the size of the icon supplied for CFBuldneURLIconFile be?
I'm guessing 57x57 and that having an #2x version present will automatically be loaded where appropriate, but can't find documentation anywhere (Googling 'CFBuldneURLIconFile' returns nothing!)
Do you mean CFBundleIconFile? (Must confess I've never heard of "CFBuldneURLIconFile" - where does this come from?)
Irrespective, there's an Apple Q&A document entitled "How are the icon files in my application bundle used on iPad and iPhone?" that lists all of the relevant icon sizes/default filenames, which should tell you what you need to know.
Irrespective, the default sizes/names are 57x57 ("Icon.png") for the non retina/iPad devices, 114x114 ("Icon#2x.png") for retina devices and 72x72 ("Icon-72.png") for the iPad, if that's relevant.
UPDATE
Think I might have found what you're after. The Information Property List Key Reference doc contains information about the CFBundleURLTypes, which states that it's effectively the URL equivalent of the CFBundleDocumentTypes. As such, you can presumably use the icon sizes it lists within that part of the documentation. (See the "Document Icons" section.)
What are my options, if any, of adding additional, arbitrary data to the standard Cocoa about dialog that is displayed by an NSApplication when it receives a orderFrontStandardAboutPanel message.
If you add a file named Credits.rtf to Resources the contents will automatically be used in the expanded standard about panel and you can put whatever info you want in the file. It will still pull the standard copyright, version info, etc from the info.plist. It is the easiest way I know of to add arbitrary info, otherwise you pretty much will have to roll your own about panel.
-[NSApplication orderFrontStandardAboutPanelWithOptions:]
Expanding further on the answers from Darrell Root and theMikeSwan above, Apple's documentation for the credits property of NSApplication.AboutPanelOptionKey states:-
The value of this key is an NSAttributedString displayed in the info
area of the panel. If not specified, AppKit then looks for a file
named “Credits.html”, “Credits.rtf”, and “Credits.rtfd”, in that
order, in the bundle returned by the Bundle class method main. The
first file found is used. If none is found, the info area is left
blank.
Expanding on theMikeSwan's answer, by accident I found that if you add a file named Credits.html to the Resources folder, it's contents get used in the expanded standard about panel. In fact Credits.html appears to override a Credits.rtf.
So your choice whether to use html or rtf format, or wire up "About" to a completely different custom window controller.
I love using the Xcode debugger. You can take a look at a variable's value and even change it.
But can I somehow DISPLAY the image that is referenced by an image variable? I know I can see its raw bytes, but it would be much more human-friendly to display a window with its contents.
Xcode might not support this. Maybe there is an external tool that would help display images?
Use Quick Look to inspect images in the Xcode debugger.
Select an NSImage or UIImage in the debugger, then click the Quick Look "eye" icon.
Like other areas of OS X, you can also use spacebar to Quick Look!
Quick Look in the debugger can also be implemented for your own classes:
Enabling Quick Look for Custom Types
The variables Quick Look feature in the Xcode debugger allows you to obtain a quick visual assessment of the state of an object variable through a graphical rendering, displayed in a popover window either in the debugger variables view or in place in your source code.
This chapter describes how you implement a Quick Look method for your custom class types so that object variables of those types can also be rendered visually in the Quick Look popover window.
If you like to work with the lldb console, use chisel command "visualize"
tip:
after the installation, you can set a conditional breakpoint after setting the UIImage with the action:
"visualize myUIImageToShowWithQuickLook"
this will show you the image automatically when the debugger stops.
EDIT:
As of Xcode 5, the debugger can show you the visual representation of UIImage/CGImageRef variables!
Xcode itself can't do it. I don't know about external tools.
What i'm doing to test images while debugging is to convert that raw data into an image-file format, like .png, and then saving it somewhere, and then i'm opening the image with any image viewing tool.
I have a piece of code for that purpose, which look basically like that:
NSData *imageData = UIImagePNGRepresentation(self.myUIImage);
[imageData writeToURL:desktopURL atomically:YES];
And i'm just copy-pasting this code where i want to see content of an image on the run.
Make sure to get rid of this code as soon as possible due to the high-cost of the conversion of UIImage to NSData
Edit for Xcode 5: Now when you hover over an image variable name, there is an "eye" icon on the right. Just click it to see the current image!
NOTE: sometimes this fails in Xcode, even if the image is correct. If this happens, OR if you don't have a UIImage variable (e.g. it's a property of another object, you can still use the older answer:
Older answer: Starting with Avraham's answer, I tried a few experiments for displaying an iOS image from lldb without having to recompile or add it to a view. I finally came up with:
e [UIImagePNGRepresentation(myImage) writeToFile:#"/Users/<userName>/Desktop/myImage.png" atomically:NO];
I keep this string in a text editor and paste it when I need it. This stores the current image I'm interested in (in this case, "myImage") to a PNG file on the Desktop. Then I can just open this file with Preview.
If you're working on an iOS device, then you can use
e [UIImagePNGRepresentation(myImage) writeToFile:[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES)[0] stringByAppendingString:#"/myImage.png"] atomically:NO];
Then you can use the Finder; select your device; "Files"; then your dev app, and copy the image to your Desktop to view it.
What if you can't get to the image via the variables view?
Echoing what #pkamb said - you can use the variables view to quick look at an image. But what if you can't get to the image?
for example I have an image at (contentViewController.view.subviews[0].subviews[1] as? UIImageView).image
but if I try to expand contentViewController in the variable view it doesn't expose my subviews
what you can do is right click, add an expression, and then you can see it!
Click the eye icon when hovering over a variable in Xcode:
You can put a breakpoint in the line of your image, and then in the debugger, just write:
po your_UIImage_object
po stands for print object, it's a GDB command which will display several useful informations about the object passed, in your case the image.
I want to set the images in my outline view to the system icons, just like on the left in the Finder. I want to get icons like Application, Documents, Desktop, etc. How do I do this?
Use NSWorkspace's iconForFile: method
NSImage *icon = [[NSWorkspace sharedWorkspace] iconForFile:#"/Applications/"];
edit:
take a look at these files, are they what you're after? Your question is a little hard to understand
$ ls /System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/Toolbar*FolderIcon.icns
/System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/ToolbarAppsFolderIcon.icns
/System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/ToolbarDesktopFolderIcon.icns
/System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/ToolbarDocumentsFolderIcon.icns
/System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/ToolbarDownloadsFolderIcon.icns
/System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/ToolbarLibraryFolderIcon.icns
/System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/ToolbarMovieFolderIcon.icns
/System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/ToolbarMusicFolderIcon.icns
/System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/ToolbarPicturesFolderIcon.icns
/System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/ToolbarPublicFolderIcon.icns
/System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/ToolbarSitesFolderIcon.icns
/System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/ToolbarUtilitiesFolderIcon.icns
There's a method in NSWorkspace that allows you to set custom icons to folders and files:
- (BOOL)setIcon:(NSImage *)image forFile:(NSString *)fullPath
options:(NSWorkspaceIconCreationOptions)options
Sets the icon for the file or directory at the specified path.
Use -[NSWorkspace iconForFileType:], and pass constants from IconsCore.h (filtered through NSFileTypeForHFSTypeCode, of course).
This article on Creating icns Icon Files should cover what you want to do. There is also an article on creating an icon so that it looks similar to the standard folder icon, which is good for consistency. Hope that helps.
Of course, this isn't really programming related.
Does this control have a name? Or is it just a bunch of simple controls merged together? If so, what controls are they?

It looks like an NSTableView with an a custom cell type and no column header. Have a look at the documentation for NSTableView's tableView:dataCellForTableColumn:row:. For columns which have the same type for all rows you may also set the cell class in interface builder.
I doubt the search box is part of the same control.
You could open the Application's Nib file to see what is in there. Look inside the application bundle. If the application is called Example then you should be able to find the Nib at Example.app/Contents/Resources/English.lproj/MainMenu.nib.
The best tool for investigating this is fscript, specifically FScriptAnywhere which will let you determine the class and much other information about any visual element of any Cocoa program (and do a lot of other interesting things with Cocoa programs).
In addition to what toholio said, an easy way to get the look and feel of the bottom button bar is with BWToolkit.
