Xamarin绑定类别返回错误:无法在静态类中声明实例成员 [英] Xamarin binding Category return error: cannot declare instance members in a static class

问题描述

我尝试将 ReFrostedViewController 绑定到c#.我使用Objective Sharpie生成界面.但是，当我使用Xamarin对其进行编译时，它会返回错误.

I'm try to binding ReFrostedViewController to c#. I used Objective Sharpie to generate interfaces. But When I use Xamarin to compile it, it return error.

 /REFrostedViewController_UIViewController.g.cs(10,10): Error CS0708: `REFrostedMenu.REFrostedViewController_UIViewController.__mt_FrostedViewController_var': cannot declare instance members in a static class (CS0708) (REFrostedBinding)

这是我的代码:

[Export ("frostedViewController", ArgumentSemantic.Retain)]
REFrostedViewController FrostedViewController { get; }

我将其更改如下:

[Export ("frostedViewController", ArgumentSemantic.Retain)]
REFrostedViewController FrostedViewController()

它可以编译，但是我不能从UIViewController中获取它.

it can compile but I can't get it form UIViewController.

REFrostedViewController reFrost = base.FrostedViewController();

返回错误:

/MainViewController.cs(43,43): Error CS0117: `MonoTouch.UIKit.UIViewController' does not contain a definition for `FrostedViewController' (CS0117) (iOS)

更新: 这是完整的代码

请帮助我，非常感谢！

Please help me, I'm very appreciate!

推荐答案

我在Github上创建了一个绑定项目和示例作为fork:

I created a binding project and sample as a fork on Github: https://github.com/therealjohn/REFrostedViewController

无法在静态类中声明实例成员"错误是由于

The "cannot declare instance members in a static class" error was because of

[Export ("frostedViewController", ArgumentSemantic.Retain)]
REFrostedViewController FrostedViewController { get; }

试图在类别中创建属性，这基本上是一种扩展方法.没有扩展" C#属性，因此您对方法的更改修复"了该错误.

Which was trying to create a Property in a Category, which is basically an extension method. There are not "extension" C# properties, so your change to a method "fixed" that error.

我不确定您还有什么其他问题，但是我所做的项目应该为您工作.

I am not sure what other issues you had, but the project I did should work for you.

享受！
