iOS将目标C块绑定到C#代码_C#_Ios_Objective C_Xamarin_Xamarin.ios

iOS将目标C块绑定到C#代码

c# ios objective-c xamarin xamarin.ios

iOS将目标C块绑定到C#代码,c#,ios,objective-c,xamarin,xamarin.ios,C#,Ios,Objective C,Xamarin,Xamarin.ios,我正在为以下目标C代码开发一个Xamarin.iOS绑定 @interface Logger : NSObject + (void)setLogBlock:(void (^)(NSString* message, void* argument))logBlock; @end 到目前为止，我有以下代码： // @interface Logger : NSObject [BaseType(typeof(NSObject))] public partial interface Logger {

我正在为以下目标C代码开发一个Xamarin.iOS绑定

@interface Logger : NSObject

+ (void)setLogBlock:(void (^)(NSString* message, void* argument))logBlock;

@end

到目前为止，我有以下代码：

// @interface Logger : NSObject
[BaseType(typeof(NSObject))]
public partial interface Logger
{
    // +(void)setLogBlock:(void (^)(NSString *, void *))logBlock;
    [Static]
    [Export("setLogBlock:")]
    void SetLogBlock(LogDelegate logBlock);
}

// This declares the callback signature for the block:
public delegate void LogDelegate(NSString message, IntPtr arg);

这可以很好地编译，但当我开始在iOS模拟器上使用它时，应用程序崩溃，出现以下崩溃：
