我正在尝试使用iCarousel（https://github.com/nicklockwood/iCarousel），并已将iCarousel.h和iCarousel.m添加到我的项目中（使用Xcode 4.3.1）。
但是，当尝试分配iCarousel的实例时（iCarousel继承自UIView），我遇到了链接器错误：
self.carousel = [[iCarousel alloc]initWithFrame:self.view.bounds];
链接器错误的完整信息如下：

有一些示例项目演示了如何使用iCarousel，并且它们编译正常。我猜想我的项目与示例项目之间必须存在一些构建设置上的差异，但我不知道可能是什么，也不知道该如何找出。是否有任何技巧可以解密链接器消息并找出问题所在？
（我正在使用与示例项目相同的框架/库）
