我正在尝试在我的 Xamarin for iOS 项目中使用 iOS 库iCarousel 。我在 XCode 中制作了静态库并将其添加到 Xamarin iOS Binding 项目中。试图从 lib .a 文件中定义导出。但是我对 Objective-C 没有任何经验，所以我很难在 iOS Binding Project 中声明导出（可以在我的目标项目中用作 dll）。我尝试使用monotouch-binding-generator来生成所需的声明，但是在编译 iOS Binding Project 后出现了很多错误。这是我对 C# 的声明。

[BaseType (typeof (UIView))]
interface iCarousel {
    [Export ("id<iCarouselDelegate>")]
    IBOutlet Id<iCarouselDelegate> { get; set;  }

    [Export ("type")]

    [Export ("reloadData")]
    void ReloadData ();

}

[BaseType (typeof ())]

    [Export ("numberOfItemsInCarousel:")]
    uint NumberOfItemsInCarousel (iCarousel carousel);

}

    [Export ("carousel:itemAlphaForOffset:__attribute__((deprecated))")]
    float CarouselitemAlphaForOffset__attribute__((deprecated)) (iCarousel carousel, float offset, (deprecated ));

    [Export ("carousel:valueForTransformOption:withDefault:__attribute__((deprecated))")]
    float CarouselvalueForTransformOptionwithDefault__attribute__((deprecated)) (iCarousel carousel, iCarouselOption option, float value, (deprecated ));

}

如何修复错误并在我的 Xamarin.iOS 项目中使用 iCarousel？这是我与 Xamarin 的第一个项目，如果问题很愚蠢，对不起。

谢谢。

那些看起来不对：

[Export ("id<iCarouselDelegate>")]
IBOutlet Id<iCarouselDelegate> { get; set;  }

[...]

[Export ("IBOutletid<iCarouselDataSource>dataSource")]
nonatomic, ah_weak IBOutletid<iCarouselDataSource>dataSource ();

[...]


[Export ("carouselShouldWrap:__attribute__((deprecated))")]
bool CarouselShouldWrap__attribute__((deprecated)) (iCarousel carousel, (deprecated ));

[Export ("carouselItemWidth:__attribute__((deprecated))")]
float CarouselItemWidth__attribute__((deprecated)) (iCarousel carousel, (deprecated ));

[Export ("carouselOffsetMultiplier:__attribute__((deprecated))")]
float CarouselOffsetMultiplier__attribute__((deprecated)) (iCarousel carousel, (deprecated ));

[Export ("carousel:itemAlphaForOffset:__attribute__((deprecated))")]
float CarouselitemAlphaForOffset__attribute__((deprecated)) (iCarousel carousel, float offset, (deprecated ));

[Export ("carousel:valueForTransformOption:withDefault:__attribute__((deprecated))")]
float CarouselvalueForTransformOptionwithDefault__attribute__((deprecated)) (iCarousel carousel, iCarouselOption option, float value, (deprecated ));

对于已弃用的，请删除它们，您将不需要它们。对于另外两个，首先将它们注释掉，然后修复它们。

还有这样的：

[BaseType (typeof ())]
[Model]
interface iCarouselDelegate {

代表通常是[BaseType (typeof (NSObject)]

无论如何，拥有一个生成器可以帮助您入门，但永远不要期望它会为您完成所有工作。不要不读这篇文章并了解一点 Obj-C的经济性
