iPad 视网膜显示屏上的黑屏

Black screen on iPad retina display(iPad 视网膜显示屏上的黑屏)

问题描述

我在 iPad 上运行的一个小游戏应用程序有问题.当我午餐模拟器 iOS 5.1 和 iPad 视网膜显示时，应用程序从我的默认图像 @x2 开始，显示图像后进入黑屏.在普通 iPad iOS 5.1 模拟器上运行良好.Xcode 只告诉我这个:

I've a problem with a little game application running on iPad. When I lunch the simulator iOS 5.1 with iPad retina display, the application start with my default image @x2 and after show the image go to a black screen. In normal iPad iOS 5.1 simulator run well. Xcode tell me only this:

2012-04-25 14:24:26.978 AppName[83696:10a03] cocos2d: Frame interval: 1
2012-04-25 14:24:26.980 AppName[83696:10a03] cocos2d: surface size: 1536x2048

有什么想法吗?谢谢

@Smamim Hossain:我把完整的 Appdelegate.m 放了同样的错误

@Smamim Hossain: Same error I put my full Appdelegate.m

推荐答案

试试这行代码- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:

try this line of code at - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:

[导演组投影:kCCDirectorProjection2D];

[director setProjection:kCCDirectorProjection2D];

希望这能解决您的问题.

hope this will fix your issue.
