在iPad视网膜显示器的黑屏

问题描述

我有一个在iPad上运行的小游戏应用程序的问题。当我吃iPad模拟器iOS 5.1与iPad视网膜显示，应用程序开始与我的默认图像@ X2和之后显示图像转到黑色屏幕。在正常的iPad iOS 5.1模拟器运行良好。 Xcode只告诉我这个：

  2012-04-25 14：24：26.978 AppName [83696：10a03] cocos2d： ：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：同样的错误我把我的完整Appdelegate.m

 if（！[CCDirector setDirectorType：kCCDirectorTypeDisplayLink]）

解决方案>

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

[director setProjection：kCCDirectorProjection2D];

希望这会解决您的问题。

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

Any idea?Thank you

解决方案

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

[director setProjection:kCCDirectorProjection2D];

hope this will fix your issue.
