Xamarin iOS 绑定项目

Question

我有一个 Xamarin.iOS 应用程序，我想引用一个绑定项目，以便我可以在我的项目中使用 .a 文件。但是当我尝试构建时出现此错误：

链接器命令失败，退出代码为 1（使用 -v 查看调用） /Users/darius/Mobile-MyApp/Source/MyApp/MyApp.Touch/MTOUCH：错误 MT5216：'/Users/darius/Mobile-MyApp/Source/MyApp/MyApp.Touch/obj/iPhone/Debug/ 的本机链接失败设备构建/iphone7.1-11.0.3/mtouch-cache/arm64/libAcrCloudSdkIosBinding.dll.dylib'。请在http://bugzilla.xamarin.com (MT5216) (Touchshop.Touch) 提交错误报告

我用这个命令行检查了.a 文件支持的架构：

xcrun -sdk iphoneos lipo -info libACRCloud_IOS_SDK.a

它输出：

Architectures in the fat file: libACRCloud_IOS_SDK.a are: armv7 i386 x86_64 arm64

我将.a 放在NativeReferences 文件夹中。

这是我的ApiDefinition.cs：

using System;

using UIKit;
using Foundation;
using ObjCRuntime;
using CoreGraphics;

}

}

还有Structs.cs:

using System;

namespace AcrCloudSdkIosBinding
{
    public enum ACRCloudRecMode : uint
    {
        remote = 0,
        local = 1,
        both = 2,
        advance_remote = 3
    }

    public enum ACRCloudResultType
    {
        error = -1,
        none = 0,
        audio = 1,
        live = 2,
        audio_live = 3
    }

    public enum HTTPResumeType
    {
        error = -1,
        resume = 0,
        restart = 1,
        success = 2
    }
}

Here 是它的来源，.a 文件也可以在那里找到 (libACRCloud_IOS_SDK.a)。 Here 是它的 cocoapod。

Answer 1

经过一周的破解，我找到了解决方案。我在 Xcode 中打开了本机项目 (Swift) 的源代码，发现它引用了 libc++.tbd。所以我所要做的就是在链接器标志中设置-lc++，以便在Visual Studio 中引用.a 库（右键单击库-> 属性-> 链接器标志）。

此外，请确保您在 info.plist 中提供了您的图书馆需要的适当权限。在我设置它所需的权限之前，它只会在我身上崩溃而不会给出任何错误。

Cole Xia 引用的工具也值得一看，因为我不得不在生成的ApiDefinition.cs 中手动挑选出我需要的接口，因为里面装满了我不需要的垃圾，并修复了一些东西也有它。所以我给了他赏金积分。我猜这个工具不适用于这个库，因为引用了libc++.tbd。

Answer 2

尝试将 Xcode 和 Sharpie 更新到最新版本，然后重新创建绑定项目。

here 可能会有所帮助。

更新：

我尝试在 official link 之后将 Sharpie 与 cocoapods 一起使用。

• 当我尝试绑定AFNetworking等著名的第三方库时，它会生成一个名为Binding的文件夹，在其中我们可以找到ApiDefinitions、StructsAndEnums和该库。

  sharpie pod -d /Users/yourName/Desktop/FolderName init ios AFNetworking && sharpie pod -d /Users/yourName/Desktop/FolderName bind
  

• 当我尝试绑定 acrcloud 时，它没有生成绑定文件夹。

  sharpie pod -d /Users/yourName/Desktop/FolderName init ios acrcloud_ios_sdk && sharpie pod -d /Users/yourName/Desktop/FolderName bind
  

所以我猜acrcloud sdk 可能有问题。
