我有一个 Xamarin.iOS 应用程序，并且我想引用一个绑定项目，以便我可以.a在我的项目中使用一个文件。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 的本机链接失败/Source/MyApp/MyApp.Touch/obj/iPhone/Debug/device-builds/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

我把它.a放在NativeReferences文件夹里。

这是我的ApiDefinition.cs：

using System;

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

    unsafe NSData Resample_bit32(NSObject pcm, uint bytes, uint sampleRate, short nChannel, bool isFloat);
}

}

并且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
    }
}

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

经过一周的黑客攻击，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 Visual Studio-lc++中为引用.a库设置链接器标志（右键单击库 -> 属性 -> 链接器标志）。

此外，请确保您在您info.plist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 提到的这个工具也值得一看，因为我不得不手动在生成的界面中挑选出我需要的接口，ApiDefinition.cs因为它充满了我不需要的垃圾，并用它修复了一些东西。所以我给了他赏金积分。我猜该工具不适用于该库，因为引用libc++.tbd.

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

这里可能会有所帮助。

更新：

我尝试按照官方链接将 Sharpie 与 cocoapods 一起使用。

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

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

    在此处输入图像描述

  • 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

    在此处输入图像描述

acrcloud所以我猜sdk可能有问题。
