I am trying to use the classes of SDWebImagein my project.

我正在尝试在我的项目中使用SDWebImage的类。

I've added the classes to my project and when I try to build it I get 7 errors:

我已将这些类添加到我的项目中，当我尝试构建它时，出现 7 个错误：

    Undefined symbols for architecture i386:

ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I am new to XCode and Objective-c so I got no idea what this errors mean.

我是 XCode 和 Objective-c 的新手，所以我不知道这个错误是什么意思。

Anyone?

任何人？

Thank you.

谢谢你。

Looks like you need to add MapKitand ImageIOto the project.

看起来您需要将MapKit和添加ImageIO到项目中。

To do that:

要做到这一点：

1. Click on the project at the top of the project navigator in Xcode.
2. Select the 'Build Phases' tab.
3. Open up the 'Link Binary with Libraries' box.
4. Click the '+'.
5. App MapKit and ImageIO frameworks.

1. 单击 Xcode 中项目导航器顶部的项目。
2. 选择“构建阶段”选项卡。
3. 打开“链接二进制与库”框。
4. 单击“+”。
5. 应用 MapKit 和 ImageIO 框架。
