Cocos2d中从场景切换到UIViewController视图方法总结

第一种：直接从场景切换到UIViewController视图（网上流传的版本）

- (void) showUIViewController:(UIViewController *) controller
{
 
   [[Director sharedDirector] pause];
    
    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:.5];
    [UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:[[Director sharedDirector] openGLView] cache:YES];
    
    [[[Director sharedDirector] openGLView] addSubview:controller.view];
    
    [UIView commitAnimations];
}

从UIViewController视图切换到场景

//返回场景视图
- (void) hideUIViewController:(UIViewController *) controller
{
    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:.5];
    [UIView setAnimationDelegate:self];
    [UIView setAnimationDidStopSelector:@selector(animDone:finished:context:)];
    
    [UIView setAnimationTransition:UIViewAnimationTransitionCurlDown forView:[[Director sharedDirector] openGLView] cache:YES];
    
    [controller.view removeFromSuperview];
    
    [UIView commitAnimations];
}

-(void)animDone:(NSString*) animationID finished:(BOOL) finished context:(void*) context
{    
    [[Director sharedDirector] resume];
}

备注：
代码1:[[[[CCDirector sharedDirector] openGLView] window]addSubview:viewController.view];
效果：添加的view会随着window是横屏还是竖屏变化，添加之后如果view下面覆盖了一个cocos2d的按钮，点击按钮的区域按钮不响应点击。
代码2:[[[CCDirector sharedDirector] openGLView]addSubview:viewController.view];
效果：不随着变化，并且底部的按钮相应点击

第二种：通过RootViewController切换（自己写的）

1、默认情况下面，cocos2d 模板并没有在AppDelegate里面包含一个RootViewController的属性，因此必须手动添加一个。

跳转到AppDelegate.h文件，并添加下面的代码：

@property (nonatomic, retain) RootViewController * viewController;

然后跳转到AppDelegate.m，synthesize之：

@synthesize viewController;

2、添加

#import "AppDelegate.h"

- (void) showUIViewController:(UIViewController *) controller
{
    AppDelegate *delegate=(AppDelegate *)[UIApplication sharedApplication].delegate;
    [delegate.viewController presentModalViewController:controller animated:YES];
   
}

从UIViewController视图切换到场景
//返回场景视图

第一种：在UIViewController调用dismissModalViewControllerAnimated 来返回，例如：

[self dismissModalViewControllerAnimated:YES];

第二种使用委托，让RootViewController来控制，例如

[appdelegate.viewController dismissModalViewControllerAnimated:YES];

备注：cocos2d 2.0的，上面那个RootViewController*viewController改成了UINavigationController *navController_；获取视图控制器改成[delegate.navController.view addGestureRecognizer:gestureRecognizer];
