Xamarin'GetNSObject'不存在於命名空間'Internal.Runtime'中

Question

我們在使用Visual Studio包裝本地obj-c庫時出現問題。 Build在NativeLibraryWrapperDef.cs中爲我們的類生成代碼隱藏，但命名空間存在一些問題：

錯誤CS0234：名稱空間'Internal.Runtime'中不存在類型或名稱空間名稱'GetNSObject'缺少裝配參考？）（CS0234）（Gmc.Mobile.Sdk.iOS）

使用Xamarin工作室的同事可以很好地構建它。其他人遇到這個問題？

/* 
The first step to creating a binding is to add your native library ("libNativeLibrary.a") 
to the project by right-clicking (or Control-clicking) the folder containing this source 
file and clicking "Add files..." and then simply select the native library (or libraries) 
that you want to bind. 

When you do that, you'll notice that MonoDevelop generates a code-behind file for each 
native library which will contain a [LinkWith] attribute. MonoDevelop auto-detects the 
architectures that the native library supports and fills in that information for you, 
however, it cannot auto-detect any Frameworks or other system libraries that the 
native library may depend on, so you'll need to fill in that information yourself. 

Once you've done that, you're ready to move on to binding the API... 


Here is where you'd define your API definition for the native Objective-C library. 

For example, to bind the following Objective-C class: 

    @interface Widget : NSObject { 
    } 

The C# binding would look like this: 

    [BaseType (typeof (NSObject))] 
    interface Widget { 
    } 

To bind Objective-C properties, such as: 

    @property (nonatomic, readwrite, assign) CGPoint center; 

You would add a property definition in the C# interface like so: 

    [Export ("center")] 
    CGPoint Center { get; set; } 

To bind an Objective-C method, such as: 

    -(void) doSomething:(NSObject *)object atIndex:(NSInteger)index; 

You would add a method definition to the C# interface like so: 

    [Export ("doSomething:atIndex:")] 
    void DoSomething (NSObject object, int index); 

Objective-C "constructors" such as: 

    -(id)initWithElmo:(ElmoMuppet *)elmo; 

Can be bound as: 

    [Export ("initWithElmo:")] 
    IntPtr Constructor (ElmoMuppet elmo);

從Internal.iOS命名空間中刪除Internal以及使用Protocol和Model屬性修復了一些問題。
