Cordova条形码阅读器编译错误Xcode 6

Question

我正在使用wildabeast barcode reader Cordova插件读取一些VIN条形码。

这在Android和iOS 7上运行良好，但自从更新到Xcode 6和iOS 8后，我无法编译处理条形码的代码。我认为这是一个配置问题，但我对iOS或Xcode没有多少经验。

以下是我收到的错误的一部分：

Answer 1

您应该将-fno-objc-arc添加到Build Phases＆gt; CompileSources＆gt; CDVBarcodeScanner.mm

本文将帮助ARC: Setting compiler flags to -fno-objc-arc and build errors

Answer 2

这个插件有很多问题，我已经发送过这种问题，而不是回复。

尝试使用scandit代替Cordova条形码阅读器。

我通过从文件中删除所有内存管理代码来修复它。我也错过了一些库，所以我也添加了它们。

这个问题也有帮助： Objective-C: ARC forbids explicit message send of 'retain'
