【问题描述】：
刚刚在我的 Mac 上更新到最新的 Xamarin.iOS 稳定版本和 Xcode 7.1。当我在 Visual Studio 中为模拟器和设备构建时，我收到以下错误：
错误 22 无法解析来自“Xamarin.iOS，版本=0.0.0.0，文化=中性，PublicKeyToken=84e04ff9cfb79065”的“System.Void Foundation.NSMutableDictionary::set_Item(ObjCRuntime.INativeObject,ObjCRuntime.INativeObject)”参考/p>
[更新] 当我将链接行为设置为不链接时，应用程序会在模拟器和设备上启动，但会因以下错误而崩溃：
Error loading /System/Library/Extensions/IOHIDFamily.kext/Contents/PlugIns/IOHIDLib.plugin/Contents/MacOS/IOHIDLib: dlopen(/System/Library/Extensions/IOHIDFamily.kext/Contents/PlugIns/IOHIDLib.plugin/Contents/MacOS/IOHIDLib, 262): no suitable image found. Did find:

我设法将问题缩小到应用程序使用的相机，具体到以下几行：
var dictionary = new NSMutableDictionary();
dictionary[AVVideo.CodecKey] = new NSNumber((int)AVVideoCodec.JPEG);
错误是
[0:] Method 'NSMutableDictionary.set_Item' not found.
Attempting to JIT compile method ... while running with --aot-only.
See http://docs.xamarin.com/ios/about/limitations for more information.
这在我更新到 XCode 7.1 之前可以正常工作。
知道如何解决这个问题吗？
谢谢！
【问题讨论】：
-
您是为模拟器还是设备构建？另外，如果您在
Link behavior中更改Don't link，它会起作用吗？您是否还有其他尚未重新编译的程序集。 -
嗨@RobertN 感谢您的快速回复。请查看更新，似乎问题与相机有关。但是在我更新之前它曾经可以正常工作。

我的 ios 项目中没有这个 EXEC 文件夹。我应该手动创建它并将所有 dll 复制到其中并引用它们吗？感觉有点脏修复。你知道为什么现在出现这个错误，但是在我更新到最新的稳定 Xamarin 代码之前它一直运行良好。
