编译时我收到了2个错误..
架构i386的未定义符号：
＆＃34; _IKImageBrowserNSURLRepresentationType＆＃34;，引自：
- ATDesktopEntity.o中的[ATDesktopEntity imageRepresentationType]
＆＃34; .objc_class_name_CABasicAnimation＆＃34;，引自： ATColorView.o中指向literal-objc-class-name的指针 ld：找不到架构i386的符号 clang：错误：链接器命令失败，退出代码为1（使用-v查看调用）
我已经包含了2个实现文件，我觉得问题正在发生......

答案 0 :(得分：1)
将第#import <Quartz/Quartz.h>行更改为#import <QuartzCore/QuartzCore.h>
还要确保已将这些库和框架链接到项目中。
