我正在尝试使用 iCarousel（https://github.com/nicklockwood/iCarousel）并将 iCarousel.h 和 iCarousel.m 添加到我的项目中（使用 Xcode 4.3.1）。
但是在尝试分配 iCarousel 的实例时出现链接器错误（iCarousel 继承自 UIView）：
self.carousel = [[iCarousel alloc]initWithFrame:self.view.bounds];
完整的链接器错误是：
Ld "/Users/Me/Library/Developer/Xcode/DerivedData/IMS-eyffphshuxtblseccxpfluamxudo/Build/Products/Debug-iphonesimulator/MyApp.app/MyApp" normal i386

有一些示例项目演示了 iCarousel 的使用，并且可以很好地编译。我认为我的项目和示例项目之间肯定存在一些构建设置差异，但我不知道它们可能是什么，也不知道如何找出。是否有任何技巧可以破译链接器消息以找出问题所在？
（我使用与示例项目中相同的框架/库）
TIA
