Question

我正在尝试在我的Xamarin for iOS项目中使用iOS库iCarousel。我在XCode中创建了静态库，并将其添加到Xamarin iOS Binding项目中。尝试从lib .a文件定义导出。但是我对Objective-C没有任何经验，所以我在iOS Binding Project中的导出声明有困难（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绑定项目后我遇到了很多错误。这是我对C＃的声明。

    float CarouselvalueForTransformOptionwithDefault__attribute__((deprecated)) (iCarousel carousel, iCarouselOption option, float value, (deprecated ));

}

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

感谢。

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，删除它们，您将不需要它们。对于其他2个，首先将它们注释掉，然后修复它们。

也有：

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

代表通常是[BaseType (typeof (NSObject)]

无论如何，拥有一台发电机可以帮助您入门，但绝不会期望它为您完成所有工作。不要经济不读this并了解Obj-C
