Windows下的Objective-C集成开发环境（IDE）的搭建 (二)

?

? ? ? ? ? ?继上一步Windows下的Objective-C集成开发环境（IDE）的搭建 (一)配置运行命令行程序后，今天来讲解一下如何使用

codeblocks配置开发使用cocoa framework开发GUI程序。

?

#include "AppController.h"
#include <AppKit/AppKit.h>

int main(int argc, const char *argv[])
{
   NSAutoreleasePool *pool;
   AppController *delegate;

   pool = [[NSAutoreleasePool alloc] init];
   delegate = [[AppController alloc] init];

   [NSApplication sharedApplication];
   [NSApp setDelegate: delegate];

   RELEASE(pool);
   return NSApplicationMain (argc, argv);
}

我们使用一个helloworld开始旅程。

?

?

? ? 这个helloworld程序共有五个文件:main.m、AppController.h、AppController.m、helloworldInfo.plist和GNUmakefile。图形界面的设计全部在代码中。

?

1. 第一步:使用codeblocks新建一个c的console程序。这里命名该工程名为gui，如图所示：
   
2. 添加一个main.c文件，将下面的代码拷贝并覆盖main.c中内容#include "AppController.h"

   1. #include <AppKit/AppKit.h>
      
      int main(int argc, const char *argv[])
      {
         NSAutoreleasePool *pool;
         AppController *delegate;
      
         pool = [[NSAutoreleasePool alloc] init];
         delegate = [[AppController alloc] init];
      
         [NSApplication sharedApplication];
         [NSApp setDelegate: delegate];
      
         RELEASE(pool);
         return NSApplicationMain (argc, argv);
      }

   ?

3. 添加一个AppController.h 头文件，内容如下：

   #ifndef _AppController_H_
   

   #define _AppController_H_
   
   #include <Foundation/NSObject.h>
   
   @class NSWindow;
   @class NSTextField;
   @class NSNotification;
   
   @interface AppController : NSObject
   {
      NSWindow *window;
      NSTextField *label;
   }
   
   - (void)applicationWillFinishLaunching:(NSNotification *) not;
   - (void)applicationDidFinishLaunching:(NSNotification *) not;
   
   @end
   
   #endif /* _AppController_H_ */		

4. 实现一个AppController.h的AppController.m文件#include "AppController.h"

   #include <AppKit/AppKit.h>
   
   @implementation AppController
   - (void) applicationWillFinishLaunching: (NSNotification *) not
   {
      /* Create Menu */
      NSMenu *menu;
      NSMenu *info;
   
      menu = [NSMenu new];
      [menu addItemWithTitle: @"Info"
                      action: NULL
               keyEquivalent: @""];
      [menu addItemWithTitle: @"Hide"
                      action: @selector(hide:)
               keyEquivalent: @"h"];
      [menu addItemWithTitle: @"Quit"
                      action: @selector(terminate:)
               keyEquivalent: @"q"];
   
      info = [NSMenu new];
      [info addItemWithTitle: @"Info Panel..."
                      action: @selector(orderFrontStandardInfoPanel:)
               keyEquivalent: @""];
      [info addItemWithTitle: @"Preferences"
                      action: NULL 
               keyEquivalent: @""];
      [info addItemWithTitle: @"Help"
                      action: @selector (orderFrontHelpPanel:)
               keyEquivalent: @"?"];
   
      [menu setSubmenu: info 
               forItem: [menu itemWithTitle:@"Info"]];
      RELEASE(info);
   
      [NSApp setMainMenu:menu];
      RELEASE(menu);
   
      /* Create Window */
      window = [[NSWindow alloc] initWithContentRect: NSMakeRect(300, 300, 200, 100)
                                 styleMask: (NSTitledWindowMask |
                                             NSMiniaturizableWindowMask |
                                             NSResizableWindowMask)
                                  backing: NSBackingStoreBuffered
                                  defer: YE
