我在openglES项目中使用xcode4,我已经从教程中添加了应用内购买代码:http://www.raywenderlich.com/2797/introduction-to-in-app-purchases
我添加了SystemConfiguration.framework但发生以下错误:

我有这样的形象:
1000x1000但只有一部分图像是不透明的,想想左边是一个实心圆,其他像素是透明的.
我想复制/粘贴图像的一部分,并选择我选择的区域:
我拖放鼠标,这样部分将是400x100但是当我粘贴时,我有一个300x76的图像.photoshop修剪了我的图像,但我希望它与我选择的图像的边界,我想要的坐标.准备400x100空白图像并复制该图像并不能解决我的问题,因为我必须将图像平移到原始位置.
如何在不修剪的情况下复制/粘贴图像?谢谢
