Ios 运行程序时，我得到架构i386:的错误未定义符号

我正在尝试将gif添加到图像视图中，因此按照web上的说明，我导入了下载的

FLAnimatedImage

和

FLAnimatedImageView

类。我将它们添加到项目中的一个组中，选择了副本，并使用了这些类。现在我得到了15个错误，如下所述

说明部分为：

错误部分是：

我该如何解决这个问题？

我已经解决了。缺少3个框架：QuartzCore、ImageIO和MobileCoReserves。对于任何有相同问题的未来查看器，您可以查看.h和.m文件，查看它们导入了哪些框架。图像：

.h: m

然后，单击project，进入构建阶段，将二进制文件与库链接，并为项目和projecttest添加框架。不太确定是否必须为这两个项目添加。嗯，这对我有效，所以希望它对其他人有效

仅供参考-您在构建应用程序时出现链接器错误，而不是运行它。看起来您至少需要将

ImageIO

框架添加到项目中。@rmaddy成功了，但现在我得到了，

architecture i386的未定义符号：“\u CACurrentMediaTime”，引用自：\uuuuu42-[FLAnimatedImage AddFrameIndexToCache:]_FLAnimatedImage.o“\u OBJC\u CLASS\u$\u CADisplayLink”中的块2，引用自：FLAnimatedImageView.o中的OBJC CLASS ref“\u UTTypeConformsTo”，引用自：FLAnimatedImage.o“\u kuttypegf”中的-[FLAnimatedImage initWithAnimatedGIFData:]在FLAnimatedImage.o中…我必须删除最后一部分

添加

QuartzCore

框架。可能还有

MobileCoreServices

框架。是的，通常这些类型的编译器错误是由于缺少框架造成的。宾果。当时正在进行FB SDK升级，这为我带来了好处。谢谢
