ios - Xamarin - 构建绑定(bind)库 Messaging.g.cs 时出错
<p><p>在为 Xamarin.iOS 构建绑定(bind)库时遇到问题。基本上我需要构建它以将 <code>dll</code> 引用到一个单独的项目中。 </p>
<p>这是我的例子 <a href="https://www.dropbox.com/s/71bprj9d6n9hog1/SWRevealViewController-XamarinBinding-master.zip?dl=0" rel="noreferrer noopener nofollow">project</a> .</p>
<p>问题是自动生成的 <code>Messaging.g.cs</code> 出现错误并在中线完成:</p>
<pre><code>//
// Auto-generated from generator.cs, do not edit
//
// We keep references to objects, so warning 414 is expected
#pragma warning disable 414

<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>我已经设法解决了这个问题。 </p>
<p>我希望这个答案对以后的其他 Xamarin 开发人员有所帮助。 </p>
<p>如果您使用的是 Objective C 绑定(bind)库，则应使用 XCode 构建并使用可用的 <code>Objective Sharpie</code> 生成 ApiDefinition.cs 和 StructsAndEnums.cs <a href="https://developer.xamarin.com/guides/cross-platform/macios/binding/objective-sharpie/getting-started/" rel="noreferrer noopener nofollow">here</a> .</p>
<p>我遇到的问题是自动生成的代码无法正确处理 <code>Delegates</code>。此外，<code></code> 属性导致解释器使用不兼容的数据类型 - 即 <code>enum</code> 结构与 <code>uint</code>。 </p>
<p>综合上述问题，我还试图在同一个项目中绑定(bind)多个 <code>.a</code> 静态库。 </p>
<p>因此，您需要在 Objective Sharpie 生成的 C# 文件中重构一些内容:</p>
<p>删除方法签名的任何重复在我的示例中，该工具生成了以下代码:</p>
<pre><code> // @optional -(BOOL)revealControllerPanGestureShouldBegin:(SWRevealViewController *)revealController;
bool RevealController(SWRevealViewController revealController);
// @optional -(BOOL)revealControllerTapGestureShouldBegin:(SWRevealViewController *)revealController;
bool RevealController(SWRevealViewController revealController);
</code></pre>
<p>为了避免编译器抛出重复的方法错误，它应该是:</p>
<pre><code> // @optional -(BOOL)revealControllerPanGestureShouldBegin:(SWRevealViewController *)revealController;
bool RevealControllerPanGestureShouldBegin(SWRevealViewController revealController);
// @optional -(BOOL)revealControllerTapGestureShouldBegin:(SWRevealViewController *)revealController;
bool RevealControllerTapGestureShouldBegin(SWRevealViewController revealController);
</code></pre>
<p>接下来，找到任何示例，其中工具已生成继承自不受支持的原语的枚举结构。 </p>
<p>所以，例如:</p>
<pre><code>
public enum FrontViewPosition : uint
{
LeftSideMostRemoved,
LeftSideMost,
LeftSide,
Left,
Right,
RightMost,
RightMostRemoved
}
</code></pre>
<p>对 <code>public enum FrontViewPosition : ulong</code> 的更改。</p>
<p>接下来移除任何<code></code>装饰。</p>
<p>最后，我发现 Objective Sharpie 对扩展方法的处理很差，导致生成的代码试图创建一个内部有虚拟方法的静态类......</p>
<p>要修复，请找到 <code></code> 的所有实例，例如:</p>
<pre><code>// @interface SWRevealViewController (UIViewController)
partial interface UIViewController_SWRevealViewController
{
// -(SWRevealViewController *)revealViewController;
SWRevealViewController RevealViewController{ get; };
}
</code></pre>
<p>并将其更改为</p>
<pre><code>// @interface SWRevealViewController (UIViewController)
partial interface UIViewController_SWRevealViewController
{
// -(SWRevealViewController *)revealViewController;
SWRevealViewController RevealViewController();
}
</code></pre>
<p>现在清理并重建，自动生成的代码现在可以正确编译。在任何需要的项目中引用绑定(bind) dll 以使用它。 </p>
<p>如果有人想在 Xamarin 中使用 <code>SWRevealViewController</code> 库，那么为了节省您的时间，您可以使用我的存储库 <a href="https://github.com/saluton-mundo/SWRevealViewController" rel="noreferrer noopener nofollow">here</a> .</p>
<p>祝你好运，玩得开心。</p>
