Question

我在iPhone上为Phonegap集成barcodescanner-plugin时遇到了一些麻烦。我从这个github存储库中获取了我的插件：

https://github.com/phonegap/phonegap-plugins/

我按照说明中的所有步骤操作，包括将所有相关源添加到项目的构建路径的步骤。我也关闭了自动引用计数。我认为每个文件都在正确的位置，但无论如何我遇到了这个错误：

ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

当我尝试插件的测试项目时，我会将其部署到iphone，但是当我按下“scan”时，我收到一个错误，即cordova-1.7.0.js文件丢失了。我在xCode上安装了xcode 4和cordova 1.7.0。在网络上我找不到解决方案或类似的问题。

有什么想法吗？

Answer 1

将以下库添加到Xcode项目中：

AVFoundation.framework

AssetsLibrary.framework

<强> CoreVideo.framework

<强> libiconv.dylib

选择目标，然后显示“构建阶段”。在Link Binary With Libraries下，单击添加按钮，然后选择上面的框架。

以粗体列出的库是导致此错误发生的原因。这是摘自https://github.com/phonegap/phonegap-plugins/tree/master/iOS/BarcodeScanner

的说明

Answer 2

我更新到xCode 4.3.3然后错误消失了。也许由于错误导致错误。插件仍然无法正常工作，但我认为这是另一个原因，并且不再与此问题相关联。

Answer 3

根据https://groups.google.com/forum/?fromgroups#!topic/phonegap/D5R450L5kLI的讨论，你可能已经完成了我刚刚做的事情。在目标设置的构建阶段下，有两组Link Binary With Libraries。我正在加入较低的空洞。将所有库添加到上面的非空库中修复它。
