cocos2d 学习笔记 - 项目启动关键代码摘录

 

总结出来的调用流程是：

main ---> AppController ---> MyNavigationController ---> IntroLayer --->HelloWorldLayer

 

<main.m>

1 int main(int argc, char *argv[]) {
2     
3     ...
4     int retVal = UIApplicationMain(argc, argv, nil, @"AppController");
5     ...
6 }

<AppDelegate.h>

 1 @interface MyNavigationController : UINavigationController <CCDirectorDelegate>
 2 @end
 3 
 4 @interface AppController : NSObject <UIApplicationDelegate>
 5 {
 6     UIWindow *window_;
 7     MyNavigationController *navController_;
 8 
 9     CCDirectorIOS    *director_;                            // weak ref
10 }
11 
12 @property (nonatomic, retain) UIWindow *window;
13 @property (readonly) MyNavigationController *navController;
14 @property (readonly) CCDirectorIOS *director;
15 
16 @end

<AppDelegate.m>

 1 @implementation MyNavigationController
 2 
 3 // This is needed for iOS4 and iOS5 in order to ensure
 4 // that the 1st scene has the correct dimensions
 5 // This is not needed on iOS6 and could be added to the application:didFinish...
 6 -(void) directorDidReshapeProjection:(CCDirector*)director
 7 {
 8     //...
 9     if(director.runningScene == nil) {
10         // Add the first scene to the stack. The director will draw it immediately into the framebuffer. (Animation is started automatically when the view is displayed.)
11         // and add the scene to the stack. The director will run it when it automatically when the view is displayed.
12         [director runWithScene: [IntroLayer scene]];
13     }
14 }
15 @end
16 
17 @implementation AppController

28                                  multiSampling:NO
29                                numberOfSamples:0];
30     director_ = (CCDirectorIOS*) [CCDirector sharedDirector];
31     // attach the openglView to the director
32     [director_ setView:glView];
33     // Create a Navigation Controller with the Director
34     navController_ = [[MyNavigationController alloc] initWithRootViewController:director_];
35     // for rotation and other messages
36     [director_ setDelegate:navController_];
37     // set the Navigation Controller as the root view controller
38     [window_ setRootViewController:navController_];
39     //...
40 }
41 //...
42 @end

<IntroLayer.h>

1 @interface IntroLayer : CCLayer
2 {
3 }

<IntroLayer.m>

1 @implementation IntroLayer
2 //...
3 -(void) onEnter
4 {
5     [super onEnter];
6     [[CCDirector sharedDirector] replaceScene:[CCTransitionFade transitionWithDuration:1.0 scene:[HelloWorldLayer scene] ]];
7 }
8 @end

<HelloWorldLayer.h>

1 @interface HelloWorldLayer : CCLayer <GKAchievementViewControllerDelegate, GKLeaderboardViewControllerDelegate>
2 {
3 }
