Apple Mach-O链接器Id错误PDColoredProgressView

问题描述

| 我正在尝试从此处使用PDColoredProgressView。它正在运行，但是由于某种原因，XCode决定没有它，并抛出27个Apple Mach-O Linker（Id）错误。 ?？有人可以解码吗？谢谢！

谢谢！ *注意：我从错误消息中删除了我的用户名和应用名称，并将其替换为x \     

解决方法

        从错误日志中，我相信您缺少项目或库体系结构设置（取决于您在上面的代码中使用的位置）。只需在项目设置中添加armv6（或等效的体系结构名称），一切就可以了。     ,        您没有安装Core Graphics库！添加核心图形库，然后在PDColoredProgressView.h中添加“ 1”。 您可能还需要QuartzCore来完成某些工作！ armv7与它无关，我不知道为什么他们在那扔了哈哈！
