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];

}

备注一点：
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];
