iOS Universal Application 支持IPHONE和IPAD的應用設置

//實現  320*180  640*960 768*1024 1536*2048 四種分辨率的圖片加載

//在AppDelegate中把起用高清的代碼註釋去掉

//if( ! [director enableRetinaDisplay:YES] )

//CCLOG(@"Retina Display Not supported");

//在ccConfig 中把-hd去掉，這是cocos2d默認起用高清的文件，和我當時定義的不符，我就去掉了

//#define CC_RETINA_DISPLAY_FILENAME_SUFFIX @"-hd"  改爲  #define CC_RETINA_DISPLAY_FILENAME_SUFFIX @""  

#define isPad (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)

//驗證是不是視網模屏

#define isIphoneRetina ([UIScreen instancesRespondToSelector:@selector(currentMode)]?CGSizeEqualToSize(CGSizeMake(640, 960), [[UIScreen mainScreen] currentMode].size) : NO)

#define isIpadRetina ([UIScreen instancesRespondToSelector:@selector(currentMode)]?CGSizeEqualToSize(CGSizeMake(2048, 1536), [[UIScreen mainScreen] currentMode].size) : NO)

#define I_PNG           @".png"

#define SD_PNG         @"-iphone-sd.png"

#define SD_IPHONE_PNG  @"-iphone-hd.png"

#define HD_PNG         @"-ipad-sd.png"

#define HD_IPAD_PNG    @"-ipad-hd.png"

//取圖片

#define IMG_GET(__filename__)  (isPad == YES ?             \

((isIpadRetina==YES)?[__filename__ stringByReplacingOccurrencesOfString:I_PNG withString:HD_IPAD_PNG]: \

[__filename__ stringByReplacingOccurrencesOfString:I_PNG withString:HD_PNG]) :  \

((isIphoneRetina==YES)?[__filename__ stringByReplacingOccurrencesOfString:I_PNG withString:SD_IPHONE_PNG]: \

[__filename__ stringByReplacingOccurrencesOfString:I_PNG withString:SD_PNG]))

//同步iphone和ipad的坐標

#define TO_X(__x__) (isPad == YES ? ( __x__ * 2.133333 ) : ( __x__ ) )

#define TO_Y(__y__) (isPad == YES ? ( __y__ * 2.133333 ) : ( __y__ ) )

#define TO_XY(__x__, __y__)     \

(isPad == YES ?                     \

ccp( ( __x__ * 2.133333 ), ( __y__ * 2.133333 )) : \

ccp(__x__, (__y__)))

//使用演示====================================

 CCSprite *goodGuy = [CCSprite spriteWithTexture:[[CCTextureCache sharedTextureCache] addImage:IMG_GET("default.png")]];

 [self addChild:goodGuy];

//上述代碼參考瞭如下網址
