Cocos2d中從情境切換到UIViewController視圖方法總結

 第一種：直接從情境切換到UIViewController視圖（網上流傳的版本）
- (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];
}

從UIViewController視圖切換到情境
//返回情境視圖
- (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];
} 備忘一點：代碼1:[[[[CCDirector sharedDirector] openGLView] window]addSubview:viewController.view];
效果：添加的view會隨著window是橫屏還是豎屏變化，添加之後如果view下面覆蓋了一個cocos2d的按鈕，點擊按鈕的地區按鈕不響應點擊。
代碼2:[[[CCDirector sharedDirector] openGLView]addSubview:viewController.view];
效果：不隨著變化，並且底部的按鈕相應點擊 第二種：通過RootViewController切換 （自己寫的） 1、預設情況下面，cocos2d 模板並沒有在AppDelegate裡麵包含一個RootViewController的屬性，因此必須手動添加一個。跳轉到AppDelegate.h檔案，並添加下面的代碼：@property (nonatomic, retain) RootViewController *viewController;

然後跳轉到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];
    
}

從UIViewController視圖切換到情境
//返回情境視圖

第一種：在UIViewController調用dismissModalViewControllerAnimated 來返回，例如：

[self dismissModalViewControllerAnimated:YES];

第二種使用委託，讓RootViewController來控制，例如

[appdelegate.viewController dismissModalViewControllerAnimated:YES];轉載來自：http://blog.csdn.net/wangqiuyun/article/details/7289104
