Doing Objects Right

by Andrew C. Stone

Using modular objects with multiple nib files to make evolving your projects easier

One of the most compelling features of writing software is that there are many ways to accomplish the same task. This gives you a large latitude for creativity, but also "the power to run off into the weeds." (I overheard an Apple Engineer using this phrase.) In this article I present some guidelines for creating usable and reusable objects, and provide source for a search and replace panel.

Our Rhapsody-based object draw and web authoring application, Create(tm), has 550 classes, and about 100 user-interface nib (NeXT InterfaceBuilder) files. This highly modular structure makes changing one component trivial and speedy. Because the nib files are loaded only when needed, it also speeds application launching.

Figure 1.

There is always a temptation to add objects directly to your main nib file because its easy to make object connections. But this bloats the main nib and causes the app to take longer to launch. Moreover, it makes multiple documents almost impossible because sometimes you need more than one instance. You also may want to take advantage of loading the nib files only when needed. This article will show you how to write an object with its own independent interface file, and how to write the glue needed to have a menu item bring up that interface. Code is included for a universal text find and replace object, "TextFinder", which can be added to the simple Word Processor from the November 1997 issue of MacTech.

#import <AppKit/AppKit.h>
@interface WordDelegate : NSObject
{
  id theText;
}
- (void)newText:(id)sender;
- (void)openText:(id)sender;
- (void)saveText:(id)sender;
@end

#import "WordDelegate.h"
@implementation WordDelegate
- (void)newText:(id)sender
{
  [theText setString:@""];
}
- (void)openText:(id)sender
{
  NSOpenPanel *openPanel = [NSOpenPanel openPanel];
  if ([openPanel runModalForTypes:[NSArray arrayWithObjects:@"rtf",@"rtfd",NULL]]) {
      [theText readRTFDFromFile:[openPanel filename]];
  }
}
- (void)saveText:(id)sender
{
  NSSavePanel *savePanel = [NSSavePanel savePanel];
  [savePanel setRequiredFileType:@"rtfd"];
  if ([savePanel runModal]) {
    [theText writeRTFDToFile:[savePanel filename] atomically:NO];
  }
}
@end

Tips and Techniques

This article won't go into style issues -- that's a topic for holy wars! However, here are some basic guidelines for developing stand-alone objects that are truly reusable:

1. Every nib file should have an owner object to which you say "+ new:"

This means that a client need know only the object's class name presenting a simple calling interface. By separating the details of the class (such as the nib name) from its use, you obtain a cushion from changes to the object. Then your client code looks like this:

id aCoolObject = [CoolObject new:(NSZone *)zone];

Note that the client determines the memory allocation zone, the NSZone, in which to create the new object by passing it as an argument. You can always pass in "NSDefaultMallocZone()", a function which returns the default memory allocation zone, or "[self zone]", which returns the zone of the calling object.

In our CoolObject's + new: method, we have

+ new:(NSZone *)zone
{
  self = [[CoolObject allocWithZone:zone] init];
  return self;  /* don't ever forget this! */
}

In its -init method, we load the user interface file:

- init
{
  [super init];
  [NSBundle loadNibNamed:@"CoolObject.nib" owner:self];
  /* place initialization code here:*/

  return self;  /* don't ever forget this! */
}

Many objects require only one instance per class. For example, Create uses just one TextFinder object, which brings up the same panel each time. For objects like these, it is more appropriate to create a class method named + sharedInstance, which might look like this:

+ (id)sharedInstance {
  // subclasses need their own instance if both classes are needed:
  static id sharedFindObject = nil;
  // get the real McCoy the first time through:
  if (!sharedFindObject) {
    sharedFindObject = [[self allocWithZone:
            [[NSApplication sharedApplication] zone]] init];
  }
  return sharedFindObject;
}

2. Name your nib file the same as the owner's class name

For each object which has a visual representation, your project directory will have three associated files: the .h, .m, and .nib. (If the nib file is localized, it will reside in English.proj, German.proj, French.proj, etc.)

If the owner's class name coincides with the nib file name, the following generic code will load a nib file based on that class name, using the NSStringFromClass() function:

#import <AppKit/AppKit.h>   /* Everything you need */

- init
{
  // Continue the designated initializer chain:
  [super init];
  // here's a fuller invocation of "loadNibNamed:" which shows the loading of the
  // dictionary with the key-value pair NSOwner, which has a value of "self".
  [NSBundle loadNibFile:[[NSBundle mainBundle] 
    pathForResource:NSStringFromClass([self class]) 
    ofType:@"nib"]
    externalNameTable:[NSDictionary 
      dictionaryWithObjectsAndKeys:self, @"NSOwner", nil]
    withZone:[self zone]];

  // place other initialization code here
  return self;
}

By making our object a subclass of an object which uses this code to load a nib, we never even have to even write a new line of code -- the nib with the name of our subclass will be loaded automatically.

Apt class naming is one of the most important aspects of creating comprehensible, not reprehensible, code. The name should clearly and concisely describe the object's function. When my custom class is a subclass of an NSObject, I like to include the superclass name in my class name. For example, SliderDualActing descends from NSSlider. Usually, nib owners will descend from NSObject, so they can have more succinct descriptive names, such as AlignPanel, TextFinder, or OpenAccessory.

3. Use the power of Objective C

We would like any text object to be able to use our TextFinder's search and replace functionality, not just our own custom subclasses. Objective C allows us use categories to add methods to existing classes. We can extend NSTextView with a category TextFinderMethods, which contains the search and replace methods. Then any NSTextView in our application will be able to respond to methods like findNext: or findPrevious:.

One note of caution about categories: if you add multiple categories to a class and define a method in more than one category, which method will be used at runtime is undeterminable. Be sure to use categories carefully. Someday categories may be thought of as the Object Oriented GOTO, but they reveal the power of a dynamic runtime system. The full set of methods that we extend the NSTextView class are defined in "NSTextViewTextFinder.m".

Objective C also provides subclassing, which allows us to reuse classes by modifying their functionality to fit specific applications. For example, in specific text objects, we might want to provide the capability to use regular expressions in our search strings. We could subclass TextFinder and modify a few of its methods without having to rework the whole object.

@implementation NSTextView(TextFinderMethods)

- (void)orderFrontFindPanel:(id)sender {
  // no variable is used - instead, we grab the sharedInstance:
  [[TextFinder sharedInstance] orderFrontFindPanel:sender];
}

4. Use the power of the AppKit

Your interface depends on being able to cause various controls (buttons, menu items) to trigger actions in your code. This is easy with the TextFinder object and the TextFinder nib file. We easily can create the necessary connections in the Interface Builder, but now that you've followed my advice to use modular design and have created many individual nib files, how do you connect the menu items defined in the main nib file to targets in other nib files? How do you connect menu items for finding text to the methods defined in the TextFinderMethods category?

The solution is the use of the AppKit's "First Responder" hierarchy.

Figure 2.

In AppKit programs, if a menu item is connected to the "First Responder" stand-in object, then when the menu item is clicked, it sends its message up a hierarchy until it reaches an object which responds to that method. If no object in the hierarchy responds to that message, the menu item automatically will be disabled. Each NSWindow in your application keeps track of which object in its view hierarchy has first responder status. This object gets the first chance to handle messages sent to First Responder. From there, the message is passed to the first responder's superview, through the view hierarchy to the window and then to the window's delegate. If the message has not yet been handled, it then goes to the NSApplication and finally to the NSApplication's delegate.

So, all you have to do is add the method's name (also called "action") to your main nib's First Responder, and connect the menu item to that action. The rest is done automatically by the AppKit objects and the runtime system. Full instructions on adding the TextFinder to an application are the next section of this article.

5. Document the object

Document what your object does and how it should be called. If you commented as you went, the documentation is mostly written. Make your API understandable by clearly explaining instance variables and methods.

6. Don't Panic

I guess this belongs in every list of guidelines! Happy Hacking.

Adding the TextFinder to Your Application

Adding the TextFinder to an existing project, like the simple word processor we built in November 1997, is as easy as adding the TextFinder.subproj to your project, adding the more complete Edit menu available in Interface Builder's Menu palette, and then connecting these menu items with the method names that we have added to the NSTextView. Here's a step-by-step guide:

  1. Download or type in the TextFinder.subproj files.
  2. Open the pWord PB.project file in ProjectBuilder.
  3. Double-Click "Subprojects" which brings up a Open Panel.
  4. Select the "TextFinder.subproj" to add this subproject.

    Figure 3.

  5. Double-Click Interfaces->sWord.nib to launch InterfaceBuilder and load the main nib file.
  6. Select the "Edit" menu item, and choose Delete.

    Figure 4.

  7. Choose the "Menu" section of IB's Palette.
  8. Drag over the "Edit" menu item onto the main menu.

    Figure 5.

    Figure 6.

  9. Now, we must add the new methods that the NSTextView understands to the First Responder stand in object. These are the methods we defined in NSTextViewTextFinder.m such as orderFrontFindPanel:, findNext:, findPrevious:, jumpToSelection:, and scrollToSelection:.
    1. Double-click the First Responder icon to load the Classes subpanel.

      Figure 7.

    2. Click the crossed "Action" icon to reveal the list of actions understood by the First Responder.

      Figure 8.

    3. Choose Classes->New Action, or Return to open a new, untitled action.

      Figure 9.

    4. Rename "myAction:" to, e.g., "orderFrontFindPanel:"
    5. Repeat a-d for each of the other actions.

      Figure 10.

    6. Save your interface file to update the First Responder completely.
  10. Connect the menu items to their corresponding First Responder action by control-dragging from the menu item to the First Responder icon, and then selecting the correct action in IB's.

    Figure 11.

  11. Recompile, and you are done! Type in some words and try out the find/replace.

The Code

The TextFinder.subproj contains TextFinder.h in Headers, TextFinder.m in Classes, NSTextViewTextFinder.m in Other Sources, and TextFinder.nib in Interfaces.

NSTextViewTextFinder.m
This is the glue which makes every text object able to do search and replace. 
These methods extend the original functionality of the NSTextView in order to 
talk to our TextFinder object. Now, you can add the complete "Edit" menu in 
InterfaceBuilder which contains the Find submenu, and it will just work....

#import <AppKit/AppKit.h>
#import "TextFinder.h"

@implementation NSTextView(TextFinderMethods)

- (void)orderFrontFindPanel:(id)sender {
  [[TextFinder sharedInstance] orderFrontFindPanel:sender];
}

- (void)findNext:(id)sender {
  [[TextFinder sharedInstance] findNext:sender];
}
- (void)findPrevious:(id)sender {
  [[TextFinder sharedInstance] findPrevious:sender];
}

- (void)enterSelection:(id)sender {
  NSRange range = [self selectedRange];
  if (range.length) {
    [[TextFinder sharedInstance] setFindString:[[self string] substringWithRange:range]];
  } else {
    NSBeep();
  }
}

- (void)jumpToSelection:(id)sender {
  [self scrollRangeToVisible:[self selectedRange]];
}
