Xcode 4 provides limited support for Interface Builder 3 plug-ins. When you try to open a nib file with plug-in dependencies, Xcode 4 displays a dialog suggesting that you update the file Figure If you agree, Xcode converts the class of custom objects built with plug-ins to the nearest AppKit class.

In that case, you must remove the plug-in dependency using Interface Builder 3 before you can edit the nib file in Xcode 4. However, changes you make to these preferences in Xcode 4 are not copied back to Xcode 3.

Similar Xcode 4 features start with Xcode 4 defaults. Changing settings in Xcode 4 does not affect your settings for these preferences in Xcode 3. If your Xcode project is in a Git or Subversion repository, you can check out your project from the repository and open it in Xcode. Use the following procedure to connect to a repository:. In the Checkout or Clone dialog, enter the path to the repository you want to clone or check out.

Fill in the name you want to use for the repository as displayed in the Organizer window and click Clone for Git or Checkout for Subversion. In the Save As dialog, specify the name and location you want to use for the working copy and click Clone for Git or Checkout for Subversion.

In the confirmation dialog, click Open to open the new working copy in an Xcode workspace window for Git or Show in Finder to see the new working copy in the Finder Subversion. For Subversion, click on the name of the new repository in the repositories organizer and fill in the paths to the trunk, branches, and tags directores. This is fine because by the time the release call is made, the property has already been retained the window. You would not want to release top-level objects in this manner in an iPhone application.

Listing Using outlets to get the top-level objects. The technique for obtaining the top-level objects differs depending on the target platform. In OS X, you must ask for the objects explicitly, whereas in iOS they are returned to you automatically. Listing shows the process for getting the top-level objects of a nib file in OS X.

The nib-loading code looks for this array object and, if present, places the top-level objects in it. Because each object starts with a retain count of 1 before it is added to the array, simply releasing the array is not enough to release the objects in the array as well. As a result, this method sends a release message to each of the objects to ensure that the array is the only entity holding a reference to them. Listing Getting the top-level objects from a nib file at runtime.

Obtaining the top-level objects in an iPhone application is much simpler and is shown in Listing In addition, by the time the array is returned, the retain counts on the objects are adjusted so that you do not need to send each object an extra release message. The returned array is the only owner of the objects. The normal nib-loading process involves reading the nib file from disk and then instantiating the objects it contains. Because they are in memory, creating successive sets of objects takes less time because it does not require accessing the disk.

Second, you instantiate the contents of the nib file to load the objects into memory. The array returned to you by the instantiateNibWithOwner:topLevelObjects: method comes already autoreleased. If you intend to use that array for any period of time, you should make a copy of it. Listing Loading a nib file using NSNib. Proxies are commonly used to support navigation controllers in iPhone applications. Proxy objects therefore represent the parts of the navigation controller object hierarchy that are already loaded in memory, because they were created programmatically or loaded from a different nib file.

Each placeholder object you add to a nib file must have a unique name. To assign a name to an object, select the object in Xcode and open the inspector window. The Attributes pane of the inspector contains a Name field, which you use to specify the name for your placeholder object. When you are ready to load a nib file containing placeholder objects, you must specify the replacement objects for any proxies when you call the loadNibNamed:owner:options: method. The options parameter of this method accepts a dictionary of additional information.

You use this dictionary to pass in the information about your placeholder objects. The dictionary must contain the UINibExternalObjects key whose value is another dictionary containing the name and object for each placeholder replacement.

The proxies dictionary stores the placeholder object information and the options dictionary wraps that dictionary. Listing Replacing placeholder objects in a nib file.

Upon the successful loading a nib file, its contents become ready for you to use immediately. Because outlets are populated with real objects when a nib file is loaded, you can subsequently use outlets as you would any other object you created programmatically. When you are done using the objects in your nib file, you must release them like any other objects. The problem is that many of these objects cannot or should not be accessed directly from the main nib file. And although you might be able to instantiate a number of custom objects in your main nib file, doing so is hardly practical or necessary.

In the case of document objects, connecting directly to a specific document object is not even possible because the number of document objects can change dynamically and can even be zero. Messaging fixed objects is a relatively straightforward process that is usually best handled through the application delegate. The application delegate object assists the NSApplication object in running the application and is one of the few objects that rightfully belongs in the main nib file.

If the menu item refers to an application-level command, you can implement that command directly in the application delegate or just have the delegate forward the message to the appropriate object elsewhere in your application. If you have a menu item that acts on the contents of the frontmost window, you need to link the menu item to the First Responder placeholder object. If the action method associated with the menu item is specific to one of your objects and not defined by Cocoa , you must add that action to the First Responder before creating the connection.

After creating the connection, you need to implement the action method in your custom class. That object should also implement the validateMenuItem: method to enable the menu item at appropriate times.

Did you try renaming? The serve the same purpose but have different formats. I know that Interface Builder, from Xcode 3. I don't use Xcode 4, but I'm surprised to hear it won't open them. Perhaps ibtool can still convert them. Not necessarily. If you have a traditional NIB, then you can probably still edit it. Add a comment. Active Oldest Votes.
