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:UIViewAnimationTransitio nCurlUp 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 setAnimationDidStopSelec tor:@selector(animDone:finished:context:)];
     
      [UIView setAnimationTransition:UIViewAnimationTransitio nCurlDown 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];
