![]() This is the most common type of object in a nib file and is typically why you create nib files in the first place.īesides representing visual objects, such as windows, views, controls, and menus, interface objects can also represent non-visual objects. Most new nib files have at least one interface object by default, typically a window or menu resource, and you add more interface objects to a nib file as part of your interface design. When a nib is loaded at runtime, the interface objects are the objects actually instantiated by the nib-loading code. Interface objects are what you add to an nib file to implement your user interface. The following sections describe how nib files used with the AppKit and UIKit frameworks are organized, the types of objects found in them, and how you use those objects effectively. The nib-loading code instantiates the objects, configures them, and reestablishes any inter-object connections that you created in your nib file. When you load a nib file at runtime, you get an exact replica of the objects that were in your Xcode document. At runtime, these descriptions are used to recreate the objects and their configuration inside your application. Most importantly, a nib file describes these objects exactly as they were configured in Xcode. It can also describe non-visual elements, such as the objects in your application that manage your windows and views. ![]() Depending on your application, avoiding nib files might require you to replace large amounts of framework behavior to achieve the same results you would get using a nib file.Ī nib file describes the visual elements of your application’s user interface, including windows, views, controls, and many others. Note: Although you can create an Objective-C application without using nib files, doing so is very rare and not recommended. This integration significantly reduces the amount of setup that is required after a nib file is loaded and also makes it easy to change the relationships between your code and user interface later. ![]() Xcode works in conjunction with these frameworks to help you connect the controls of your user interface to the objects in your project that respond to those controls. Both of these frameworks support the use of nib files both for laying out windows, views, and controls and for integrating those items with the application’s event handling code. You can also change many aspects of your user interface later without rewriting any code.įor applications built using the AppKit or UIKit frameworks, nib files take on an extra significance. Because you can see the results of your changes instantly, you can experiment with different layouts and configurations very quickly. With nib files, you create and manipulate your user interfaces graphically, using Xcode, instead of programmatically. none // Set Highlighted Cell files play an important role in the creation of applications in OS X and iOS.
